1. Cultural special paper

1) Carbonless copy paper (carbonless paper)

Internationally, it is generally believed that the first special paper was produced in 1945 NCR paper was successfully developed by the National Cash Register Company of the United States. This kind of paper is not obviously different from ordinary paper in appearance, but it can be used to copy, producing the same effect as blue carbon paper, and will not stain fingers and clothes, making it more convenient and hygienic. Since no carbon components are used to make this paper, it is named carbonless paper, or carbonless paper for short.

Why should carbonless copy paper be classified as special paper? First of all, paper has a special structure. Carbonless paper is generally divided into upper, middle and lower pages, and each page has three different layers of structure, which is not available in ordinary paper in the past; secondly, the added chemicals are special. For example, carbonless paper requires the preparation of microcapsules and the use of colorless dyes, developers, etc., while ordinary paper only needs to add general chemicals (such as rosin gum, modified starch); third, the processing technology is special. The application process of carbonless paper varies according to different surface layers, requires multiple applications, and the processing technology is relatively difficult. Ordinary paper sometimes does not need to be processed separately; fourth, the application field is special. Carbonless paper is mostly used in financial, aerospace, electronic communications, national defense and military sectors.

2) Special printing paper for books and periodicals

It is generally believed that printing and publishing of books and periodicals is inseparable from offset paper, offset printing paper, coated paper and the like. However, due to the rapid advancement of printing technology and the competition among multiple media, many high-end printing papers (with various names, such as Monken paper, embossed paper, etc.) have become a new choice in the book publishing industry. These special paper products, which are suitable for special printing/packaging, come in many varieties and are quickly entering the book and periodical publishing industry. They break the old monopoly of "printing paper" and the old stereotype of standard formats, allowing special (art) paper to suddenly emerge and change the appearance of books and periodicals. A new look, attracting more readers and collectors.

3) Anti-leak paper

A paper with a specially treated surface developed by a Canadian company. Where confidentiality is required, just use the matching special pen---a scriber to mark it out. The pen's water is transparent and colorless, and it produces a complex pattern when it comes into contact with the paper. The pattern does not hinder the reading of the article, but it will destroy the normal operation of the sensitive components of the copy machine and cause a black band to appear in the confidential area of ??the copied article, thus achieving the purpose of confidentiality.

4) Tamper-proof paper

France has developed a tamper-proof security paper "Secura". It uses advanced compression printing technology. When the pressure generated by the pen tip, dot matrix printer or letterpress printing is applied to the "Secura" paper, it will cause a chemical reaction with the inside of the paper fibers and the back of the paper, which will appear on the back of the paper after one minute. Mark or text pattern. On the front side of the paper, there is a layer of chemical agents that can prevent the document from being painted, rubbed, scratched, scratched and color copied. If organic solvents, redox agents, acids, alkalis and other solvents are used to modify the paper, the preparation will enter the paper fiber and leave a color mark in it. There is also a layer of toner attached to the surface of the paper. If you scratch it with an eraser or a knife, a colored mark will be produced on the surface of the paper and inside the paper fibers.

5) Sounding paper

Japan's Olympus Optical Industry Company has developed a kind of paper that can make sounds. A special scanning pen is used to read the fine-point barcode printed on the paper. You can hear the sound. The company works with publishers to publish books that speak volumes. The book records sound using fine dot barcodes 8.4 mm wide, and with the help of a scanner pen, readers can hear the sound through headphones.

6) Pressure-resistant paper

A kind of paper with strong elasticity and good toughness made by adding synthetic fibers to wood fibers and then undergoing special processing. It can be used to print books, newspapers, magazines, business cards, etc. It is durable.

7) Nano waterproof paper

In daily life, ordinary paper is afraid of water and moisture; although offset printing paper and electrostatic copy paper are waterproof and moisture-proof, they are inconvenient to write on. In addition to maintaining the original writing, copying and other functions of paper, nano-waterproof paper also has special properties that ordinary paper does not have, such as super hydrophobicity and moisture resistance, improving the strength of the printing surface, and reducing the expansion and contraction rate. Since its added cost is only about 10% of the cost of ordinary paper, this nano-waterproof paper has good market potential and can be used to print water-resistant books and periodicals, long-term preservation documents, military maps, etc.

8) Safety thread paper

Safety thread is also called anti-counterfeit thread and Chamberlain thread. It is a thread made of metal or plastic that is added to the paper using a special device during papermaking. An anti-counterfeiting mark at a specific location. With the development of science and technology and the improvement of technology, safety wire technology continues to develop and there are many varieties.

Currently commonly used are: invisible single-color and two-color fluorescent safety threads; thermal safety threads that appear opaque pink at room temperature and display microprinted text on the heated area when the temperature reaches 37°C with a finger. Thread; safety thread printed with UV fluorescent text; safety thread whose color changes with the viewing angle; laser holographic safety thread that can not only change color but also have pattern changing function; metal and magnetic safety thread detected with specific instruments; prevent the use of colored The counterfeit sections of the copy machine are exposed to the window safety line on the paper surface. This safety line, when viewed under the light, is a visible complete or intermittent (window) line embedded in the paper base. The shape of the line can be linear or wavy. Shape, zigzag, etc. When a copy machine is used to copy printed matter using this technology, the exposed metal lines will turn into black intermittent dotted lines; magnetic safety lines made by coating with magnetic paint, applying dyes, local metal plating, mesh holes, etc. . Safety thread paper technology is often used in box packaging materials such as cigarette packs.

9) Anti-copy paper

The so-called anti-copy is to prevent the original from being copied through a copier to produce a product that is exactly the same as the original, thereby preventing it from being forged. The characteristic of anti-copy paper that uses background pattern printing to hide text, patterns, and patterns is that the background pattern is printed on the paper with almost no obstacles when reading or identifying. This is an extremely fine dot pattern or hidden pattern. Text and pattern printing. Once copied, the pattern or hidden text or pattern will appear clearly.

A VIOD marking paper

Contains a substance that prevents color copying. When anti-counterfeiting printed matter such as trademarks is copied with a color copier or scanned with a scanner, it will clearly display "VIOD" ” words, the logo is printed in black and white. This VIOD logo can be used on the packaging of CD-ROMs, computer software, cosmetics, etc.

B Colored anti-copy paper

The principle is to use specific dyes and pigments to color the base paper, and then expose it during copying. Because the text image part and the background have the same absorption, the contrast disappear. When the photoreceptor is exposed, it is almost fully exposed and there is no contrast. The copy becomes completely black and it is impossible to form an image. The disadvantage of this method is that the original is not easily identifiable. The color currently in practical use is reddish brown.

C Photochromic anti-copy paper

The so-called photochromism is that the color of certain properties changes after being exposed to light, and returns to the original color after leaving the light. Photochromic anti-counterfeiting paper is anti-counterfeiting paper containing these substances. This kind of anti-copy paper is a paper base coated with chemically discolored (colored or decolorized) materials, which are excited and discolored by exposure during the copying process, so that there is no difference in contrast between the background part and the image part and cannot be copied. After the original leaves the copier, the background portion returns to its colorless state again.

D Photoluminescence anti-counterfeiting paper

When copying is exposed, it emits light due to light excitation, and the copy becomes white and cannot be copied.

E Fluorescent paper

Uses the paper base to contain fluorescent substances (fluorescent additives are added during the papermaking process or fluorescent fibers are used), and the length of the emission wavelength of the fluorescent substances is used during the copying process. Make the copy completely black or white to prevent copying.

F Diffusion anti-copy paper

This type of anti-copy paper is coated with a layer of material with a small diameter and high emissivity on the surface of the paper base, such as aluminum powder, 10 grains Large-diameter titanium dioxide, glass particles that absorb infrared rays, etc., cover or reduce the contrast between the paper and the image through diffuse emission on the paper surface, making the copy appear black to achieve the purpose of preventing copying.

G polarized anti-copy paper

This kind of anti-copy paper is made of polarizing film and covered on the paper base. It uses the dichroism of light during copying to reduce the number of words and characters. The contrast between the paper and the photosensitive drum causes the copy to appear black.

H Thermochromic anti-copy paper

This kind of anti-copy paper is a paper base coated with a thermochromic material that is colorless at room temperature. When copying, due to The copier generates heat and color, causing the contrast between the image part and the background to disappear and making it impossible to copy. When returned to normal temperature, the color disappears, and the background part, the original, returns to its original colorless state.

Currently used are colorless materials that are achromatic with fluoranine, phenol chromogen, aminophenylmercury dithizone salt, etc.

2. Lifestyle special paper

1) Clothing paper

In the past, "cloth paper" obtained by chemical treatment of raw paper was used as Tablecloths, sheets, hand towels, etc., for one-time use. However, in recent years, calls for protecting resources and the environment have become increasingly louder, and the "single use" view has been regarded as "obsolete". As a result, "clothing paper" was developed abroad. This paper is as flexible as cloth and can be ironed. Paper dresses made of this kind of paper are novel in style and pleasing to the eye. The wedding dress made of costume paper is unique. Since wedding dresses are only worn once at the wedding, it is more economical to make them out of paper.

2) Water-soluble paper (water-soluble paper)

Water-soluble paper can completely dissolve by itself after being soaked in water for one or two minutes. If stirred or washed, it will dissolve faster. This kind of paper was originally developed in the United States in response to the special requirements of the federal security department. It was kept secret for a long time, so its scope of use was very narrow, and it was not allowed to expand propaganda at will. However, scientific knowledge is constantly spreading, so various water-soluble papers later appeared.

The appearance of this kind of paper is similar to that of ordinary paper, and the production process is basically the same. However, the selection of raw materials and post-processing technology are different. During papermaking, the requirements for pulp dispersion, web evenness and decylinding are high. The carboxymethylcellulose sodium salt contained in water-soluble paper is at least two-thirds, and the other third is pulp and additives. The pulp is beaten and mixed with carboxymethylcellulose sodium salt. After adjustment, it is sent to the paper machine for papermaking. The paper needs to be processed to turn it into a soluble chemical structure, and finally it is cut and packaged. From post-processing to packaging, all operations are strictly prohibited from involving water to ensure the quality of the finished paper. This kind of water-soluble paper can be used for writing and printing. When necessary, flush the paper into the toilet and the paper will disappear without a trace. It can be used to package medicines or condiments and can be used directly without opening it. It can also be processed into women's cosmetics. Paper is very popular among consumers.

3) Vacuum cleaner bagging paper

It is used for vacuum cleaners to collect dust. It is a one-time use and is consumed in large quantities in Europe, America and developed countries. The paper is generally composed of two or three layers, and the product quality requirements are relatively high. The paper needs to be loose and breathable to facilitate the exhaust of the vacuum cleaner, and it also needs to have high burst resistance and tensile strength. Domestic paper-making enterprises can modify small paper machines to produce vacuum cleaner bagging paper. After producing the base paper, they can then process and make bags themselves, and then export it with professional vacuum cleaner suppliers.

Characterized by stable quality and high level of industrialization. Papermaking companies can transform 1092mm rotary screen paper machines for production. Paper rope paper comes in many colors and has strong toughness and tensile properties. There are now finished paper samples for manufacturers to choose from.

5) Lampshade paper

It is mainly used to produce lampshade materials for mid-to-high-end lighting, and there are many varieties. The highest-end ones include imitation parchment paper, which has simulated bloodshot, wrinkled, and leathery textures of varying thicknesses; mid-range papers have silk textures and thick and thin linen textures; and there are also handmade papers with added decorations such as flowers and leaves. Taste. These copying effects are all intended to increase the antique, artistic, and abstract feel of the lighting under soft light, so as to improve the artistic taste and commercial value of the lighting. The manufacturing technology of lampshade paper mainly relies on technical means such as raw material ratio and manufacturing process to increase strength, and even increase flame retardant properties, with rich variations. Such products need to be combined with art, and it is possible to produce multiple varieties and small batches of art special papers.

6) Cloth-replacing paper

In fiber raw materials, some wet strength agents are added to synthetic paper, which can be used to make disposable clothes, bed sheets, tablecloths, hand towels and other special products, which is hygienic , and convenient.

7) Washi paper

The "Wahi paper" developed in Japan has low basis weight, wet strength, high elongation, soft paper, resistance to scrubbing, and can be cut into narrow pieces. It is mainly used for pressure-sensitive collagen paper, artificial flower paper and disposable wet towel base paper. Especially when used as raw materials for towels and bath towels, good results have been achieved. Compared with other materials, towels and bath towels produced with "Washi" have strong unevenness and good scrubbing effect. The paper is soft when exposed to water, does not hurt the skin, has moderate irritation and friction, especially its water absorption, water permeability and speed. It has excellent drying properties and is very suitable for bath towels, making it a popular new product on the market.

8) Paper for textile materials

In recent years, Japan has used paper as a textile raw material based on the production and development of "Waji" paper, and has gone through processing techniques such as dyeing and twisting. Paper threads of varying thicknesses are formed, which are successfully used in the production of textiles. At present, the paper used for textile materials is developing towards thin wires (narrow strips of paper), such as 10mm, 6mm, and 4mm wide paper tubes. The narrower the paper, the finer the twist, and the higher the strength requirements. The types of textiles that can be produced The more. High-end T-shirts produced with fine paper threads and twisted silk threads are already on the Japanese market. Their air permeability, sweat absorption and quick-drying properties are much better than cotton fabrics. The production is difficult and has high technical content.

3) Special paper for construction and building materials

1) Construction paper

The special paper used in construction can be exemplified by the "paper construction" selected at the Sydney Olympics. "For example. The gypsum cardboard, tar paper, wallpaper board, etc. used in the past cannot compare with today's new construction paper in terms of strength, stiffness, or waterproof performance. In addition to plant fiber paper, new construction paper also uses polymer compounds.

2) Composite floor wear-resistant layer paper

In recent years, my country has introduced a large number of composite flooring production lines. The demand for composite floor surface wear-resistant paper is increasing, and the wear-resistant paper quantity At 30--60g/m2, the width of the roll paper is about 1300mm. The paper has high tensile strength and good wettability. The raw material is long fiber, which has good body absorption when laminated with other resin materials during compounding. Composite flooring has gradually become a new type of flooring products and requires the cooperation of professional material supporting manufacturers for production. As the usage of composite flooring increases, wear-resistant paper has greater added value and profit margins. Now is a good time to develop wear-resistant paper.

3) Colored cotton brick lining paper

Colored cotton brick is a new type of building decoration material that makes various buildings look more magnificent. Decorative lining paper bonded with colored shaft cotton bricks can improve the production efficiency of cotton bricks and also facilitate construction on construction sites. This kind of lining paper looks the same as ordinary paper in appearance, but its physical indicators are relatively special. It requires a certain dry and warm strength and good water absorption performance.

4) Paper steel

Paper steel is a contemporary high-tech achievement. It is a new building material made by mixing extremely fine metal wires and fibers into paper pulp and using papermaking methods. , also known as metal fiber paper. The thin one is only a few tenths of a millimeter, as thin as paper, but has the same strength as steel; the thick one can be made of several layers of thin paper steel sheets bonded with synthetic resin, with a thickness of 2-3 cm. Paper steel can be made into plates, or stamped and rolled into grooved, corrugated and various special-shaped materials.

As soon as paper steel came out, it showed strong vitality and broad prospects. It plays a wide range of roles in industry, agriculture, construction, national defense and military industry, daily life and other fields. It has been used abroad to manufacture cars, train carriages and aircraft fuselage inner wall materials. Lightweight houses made of paper steel can be assembled and transported, and are suitable for temporary workshops, classrooms and camping houses. The United States has used paper steel to construct a paper bridge with a span of 15 meters and a bridge deck of about 3 meters wide. It can not only pass pedestrians, but also small tractors and 2.5-ton jeeps, and can be disassembled and assembled at any time. All the paper and steel materials used to build a bridge can be transported away in a Jiefang brand car, so it is suitable for military use. Thin paper steel is as light and soft as gauze and plastic cloth, and can be made into daily necessities such as tablecloths, curtains, sheets, etc.; thicker paper steel can be stamped into various utensils, such as bowls, basins, boxes, etc. All plastic products can be replaced with paper steel and will not age. Paper steel can also replace wood to make cabinets, wardrobes, boxes and other furniture.

Japan has developed non-combustible paper using calcium silicate as raw material, which can be used as wallpaper and heat-resistant filler. During production, silicic acid powder and lime water undergo a thermal reaction to extract fibrous calcium silicate, and then add glass fiber and paper reinforcement. Non-combustible paper can replace asbestos materials whose use is restricted due to environmental concerns.

6) Furniture paper and paper furniture

Paper furniture first appeared in the 1920s. Paper furniture uses paper as the main raw material. The paper is first treated with waterproofing, and then wrapped into thin threads with yarn. Then these "paper threads" are woven into "paper cloth" using a textile machine. When weaving cloth, the key step is to weave stainless steel wire into the weft thread so that it can withstand greater pressure. The woven "paper cloth" is cut and matched with frames of different materials. The edges are collected with perfect weaving techniques, then painted and then glued to become a piece of furniture that is both beautiful and practical.

The material of paper furniture is taken from special paper fiber. This paper fiber is light and tough, not afraid of moisture, does not hide dirt, is waterproof, insect-proof, sun-proof, anti-corrosion, mildew-proof, and not brittle. ation and other advantages. The visual sense is that the colors are gorgeous and plump, the touch is smooth and delicate, no matter high heat or cold, wet or dry, it will not fade, not crack, and is not afraid of various outdoor environments in the open air.

The breathability of paper chairs is good, and the thermal conductivity of paper is similar to that of wood, making it cool but not stuffy when used in summer; when used in winter, the body does not feel cold, and it can also be used with chairs It is more convenient to use the pad.

Paper furniture comes in a variety of colors and can be combined with different home spaces to create a variety of home environments. In addition, for paper furniture, you can often change their cloth covers to make them changeable and look new.

4) Packaging special paper

1) Stretch paper

Japan has successfully developed a paper that uses all wood and pulp as raw materials without adding any synthetic resin. Stretch paper that can be directly pressed into packaging containers. This kind of paper is 5 to 10 times more stretchable than ordinary paper. If a special metal mold is used, it can be directly pressed into paper packaging containers of various shapes. The paper packaging container is as strong as plastic packaging containers and can be used to package daily necessities and food. Not only is the production cost very low, but it can also be recycled and is expected to replace plastic packaging containers.

2) "Npimold Paper" deep stamping paper

Japanese Nippon Paper Company has developed a deep stamping paper completely made of natural fibers and named "Npimold Paper". The stretchability is 5-10 times that of ordinary paper. This kind of stamping paper can suppress text, patterns and three sets of curved surfaces during molding, similar to the processing of plastic products. Smoothing the convex image can achieve better sealing. The product can be produced using current plastic product equipment and molded according to the design plan. Since there is no need to heat and soften before processing, production efficiency can be improved and energy can be saved.

3) Paper grain bags

Traditional flour packaging bags are still unsatisfactory in terms of strength, moisture-proof performance and other aspects. At present, the basic test of high-gram weight chicken skin paper used to make large and small flour packaging bags has been successful. This kind of white chicken skin paper produced using imported bleached softwood pulp has high whiteness, no fluorescence, strong tensile strength, and meets hygienic requirements. The paste bottom bag made with it adopts the trapezoidal bonding method. Each layer is bonded independently, and the layers are bonded together with dots of paste to make it stronger.

Compared with ordinary paper bags, this new type of paper bag is 1.5 times stronger. A four-layer paper bag filled with 25 kilograms was dropped freely 15 times from a height of 1.5 meters without breaking the bag. This kind of paper bag itself is hygroscopic. Under the same conditions, the shelf life of flour packaged in paper bags is 2-3 months longer than that in cloth bags. Another feature is that it is non-toxic, odorless, pollution-free and meets food hygiene standards.

The advantages of paper grain bags such as hygiene, quality preservation function and strong elasticity have added strong market vitality to them. We should develop such products as soon as possible and occupy the market share as soon as possible. , has become a new topic for people in the paper industry to think about.

4) Special food packaging paper

A solar thermal insulation paper

is a paper developed in the United States that can convert solar energy into thermal energy. It acts like a solar collector. If you use it to package food and place it in a place exposed to sunlight, it will continue to collect heat, and the food can be heated and kept warm. The heat will not dissipate until the paper is opened.

B Far-infrared packaging corrugated paper

The far-infrared packaging corrugated paper developed in Japan can be processed into packaging boxes and used to package fruits, which can extend the retention period of the activated state of water molecules in the fruits. As a result, the shelf life of fruits is more than twice that of ordinary corrugated boxes. This kind of paper is made of corrugated paper made of 100% natural pulp. It is first coated with a layer of ceramic that can release far-infrared rays, and then a layer of polyethylene film is coated on top of the ceramic to prevent the ceramic from falling off.

C Edible antiseptic paper

Japan has developed a kind of antiseptic paper that can be used for food packaging. Its production process is: first immerse the base paper in an ethanol solution containing 20% ??succinic acid, 33% sodium succinate and 0.07% sorbic acid, and then dry it. Food packaged with marinade in this paper can be stored at a high temperature of 38°C for 3 weeks without deterioration.

D dehydration function packaging paper

Japan has developed a packaging paper that has dehydration function without heating or additives. This kind of paper chooses a semi-permeable membrane that can permeate water as the surface material, and places high-osmotic pressure substances and polymer water-absorbing agents on the inside. Since the osmotic pressure difference of the water in the food in the liquid state can move to the high osmotic pressure substance through the semi-permeable membrane, these water molecules are fixed by the polymer water-absorbing agent. This wrapping paper will not destroy food tissue cells. It absorbs water along the intercellular space. It can not only absorb moisture on the surface of the food, but also absorb moisture deep inside. It also has the function of absorbing water at low temperatures. This kind of wrapping paper can inhibit the activity of enzymes, prevent protein decomposition, and reduce microbial reproduction, thereby maintaining the freshness of food, concentrating umami ingredients, removing moisture, and improving toughness.

E Okara paper

is made from waste tofu dregs into water-soluble paper, which can be widely used for packaging of instant noodles, condiments, barbecue, cakes, and fruits. Its preparation method is: add fatty acid and protein acid to tofu residue, let it decompose, then wash it with warm water, dry the finished fiber, and then add yam, taro, dextrin, oligosaccharide, polypropylene glycol and other binding agents to make it. made.

F pomace paper

Japanese Takasaki Paper Company has developed a method to produce pomace paper using apple pomace discarded from the food industry. The production method is simple: remove the seeds from the pomace and Pound it into pulp and add an appropriate amount of wood fiber to make it. This kind of pomace paper breaks down easily after use and can be burned or composted. It can also be recycled and remade into paper, making it less likely to pollute the environment.

G Special laminated paper packaging

The Italian Unifill company cooperates with Nippon Paper to launch two types of easy-to-peel shell-shaped paper in the Japanese food industry Packaged cheese. This kind of paper packaging using special coating technology pioneered by Unifil is favored by the Japanese.

H Vegetable Paper

Vegetable paper was first developed in Japan and is also called paper vegetable.

The most unique characteristic of vegetable food is that it is rich in dietary fiber, multiple vitamins and minerals. Dietary fiber is quite stable during processing, so the processed paper vegetable products have very little nutritional loss and the product has a small water content (approximately 10%) for easy transportation and storage. It not only increases the added value of vegetables, but more importantly, solves the problem that vegetables are perishable and difficult to store.

The research on vegetable paper products has opened up a new way for the deep processing of agricultural and sideline products, and has important practical significance for promoting agriculture and agricultural product processing.

Paper dishes can be used in many fields such as convenient snack foods and edible packaging. There are two types of edible paper. One is to use vegetables as the main raw material, beat the vegetables, and dry them after forming. The other is to refine starch and sugar, then add other food additives, and use a process similar to the papermaking process. Method shaping. From the perspective of application and development prospects, green products using vegetables as raw materials have greater potential. As far as the production process is concerned, there are two main methods. The first method is the compression molding method, which lays the slurry flat on the forming plate and bakes it twice. The other method is the roll molding method, in which the slurry is passed through two counter-rotating machines. Press roller, directly press into paper shape, slice and shape and then dry to obtain the finished product.

At present, only Japan has produced vegetable paper on a certain scale in the world. The processing technology and equipment have entered the fourth generation, and the maximum daily output can reach 30,000 sheets per production line per day.
