Abstract: Carton packaging refers to the packaging of products in paper boxes in order to protect the products, facilitate storage and transportation, and promote sales during the circulation process. Carton packaging is the most widely used packaging method. Different from wooden box packaging, woven bag packaging, cloth bag packaging, and plastic box packaging, carton packaging has the characteristics of easy material selection, light weight, easy printing, easy design and molding, and low cost. It is widely used for sales packaging and transportation packaging of goods. Commonly used marks for carton packaging. What are the classifications of cartons

1. Identification mark

(1) A trade mark is a specific mark for the batch of goods, or the code name of an export company or foreign company. . Concise graphics such as triangles, rhombuses, quadrilaterals and circles are mostly used, along with substitute abbreviations.

(2) Product names and trademarks are represented by patterns and text, which must be conspicuous and generally use Chinese and foreign languages.

(3) Destination sign is a place name sign used to indicate the destination of goods. In order to accurately transport goods to their destination, the full name of the place must be written in writing. The loan collection location is usually marked on the upper right corner of the carton.

(4) The item number and quantity mark are used to indicate the item number and quantity of items in the box. Measurement methods include box, single, branch, pair, set, dozen, etc. Generally speaking, the county uses Chinese and foreign languages. Foreign languages ??are often abbreviated because of the long letters. (5) Volume and weight signs indicate the actual outer dimensions (length × width × height) and weight (net weight and total weight) of each carton to facilitate transportation. The department refers to these data to select the mode of transportation and the method of stacking the goods. ·

(6) The manufacturer and country name signs indicate the name of the product's manufacturer. Export products can use "Made in the People's Republic of China" or "Made in China". Some products can indicate the province and city where the product is manufactured. , such as "China, Guangzhou", "-" are marked in both Chinese and foreign languages.

2. Instruction marks

According to the characteristics of the goods, some items are easily broken, damaged and deteriorated. The requirements and precautions for loading, unloading, handling and storage of goods, such as "upwards", "moisture-proof", "handle with care", "sling from here", "center of gravity", "protect from heat" , "anti-freeze", "stack height", etc. Commonly used indicators are as shown in the figure.

1. Definition signs

Usually used as a wrapper or outer protective layer for goods. Used items. The volume of the carton changes depending on the size of the product. The carton usually has "handle with care", "afraid of moisture", "up", "stack limit", "afraid of sunlight", "moisture-proof" and "quality and safety". Various prompts such as "No rolling", "Do not trample", "Pay attention to fire prevention", "Fragile items", "Green environment", "Afraid of heat", "Food", "Prevent odor", etc., protect the contents from harm.

2. Classification standards

According to different paper types, there are corrugated boxes, single-layer cardboard boxes, etc. Commonly used cartons are three-layer and five-layer, and seven-layer is less commonly used. Each layer is divided into lining paper, corrugated paper, Core paper and surface paper. The surface paper includes tea board paper and kraft paper. The core paper is made of corrugated paper. The color and feel of each paper are different, and the corrugated paper produced by different manufacturers also has different corrugated shapes. , the functions of the bonded corrugated board are also different. Even if the same quality of surface paper and lining paper are used, the performance of the formed corrugated board is also different due to the difference in flute shape. See Table 1. Corrugated cardboard made of type A stare blankly has good buffering properties and a certain degree of elasticity. Type C going A while at stiffness and impact resistance are better than type A stare blankly; type B stare blankly has a higher arrangement density. The surface of the corrugated board is flat, the pressure is high, and it is suitable for printing; the E-type flute is thin and dense, which shows its rigidity.

When producing and manufacturing corrugated boxes, it is generally based on cartons. To distinguish the box type.

The box structure of corrugated boxes is commonly used in the international community jointly developed by the European Federation of Corrugated Box Manufacturers (FEFCO) and the Swiss Cardboard Association (ASSCO). Type standard. This standard is approved by the International Corrugated Board Association and is used internationally. According to the international carton box type standard, the carton structure can be divided into two categories: basic type and combined type.

Basic type is the basic box. Type, there are legends in the standard, generally represented by four digits, the first two digits represent the box type, the last two digits represent different carton styles in the same box type, for example: 02 represents a slotted carton; 03 represents a slotted carton. Fitted cartons, etc.

The combined type is a combination of basic types, which is composed of more than two basic box types and is represented by multiple sets of four-digit numbers or codes. For example, the upper flap of a carton can be type 0204, and the bottom flap can be type 0215.

With the popularity of fine goods, there are more and more white cardboard boxes, and this industry is becoming more and more closely related to printing. At the same time, it also promotes the development of computer graphic design.

China's national standard GB6543-86 refers to the international box standard series and stipulates the basic box types of single corrugated cartons and double corrugated cartons for transportation packaging.

However, in the late 1980s, with the changes in distribution channels and market sales forms, a number of non-standard corrugated boxes with novel structures emerged, and with each new structure With the birth of cartons, almost all corresponding fully automatic packaging systems or packaging equipment have come out, which has greatly enriched the application fields of cartons.

3. Other categories

International standard cartons have formed a complete system and regulations. Production companies only need to select materials and process them according to the standards. The emergence of various novel non-standard cartons brings about a revolution in the corrugated carton industry. New non-standard cartons mainly include rolled cartons, separated cartons, triangular prism cartons and large cartons. Roll-wrapped cartons

Roll-wrapped corrugated boxes are somewhat similar to 0210-type boxes. The difference is that in 0210 boxes, the fluting direction is parallel to the width of the cardboard, while in roll-wrapped cartons, the fluting direction is parallel to the length of the cardboard; The connector of the 0210 box is connected to the main box surface, while the roll-wrapped carton is connected to the side box surface; the indentation line of the inner and outer flaps of the 0210 box is in a straight line, but the roll-wrapped carton is different.

In terms of use, it is not like the 0210 type carton, where the entire carton making process is completed in the carton factory, and then the contents are filled into the box after arriving at the user's factory. Instead, it is just the die-cut carton. The carton blank is handed over to the packaging user, who uses an automatic packaging machine to place the contents and then wrap it into boxes.

Compared with standard boxes, the characteristics of roll-wrapped cartons are that they use less material, the cartons and the contents are closely connected, and high-speed automation can be achieved.

Separable cartons

Separable cartons can be divided into two or more during the circulation process, which mainly solves the contradiction between mass production and small batch sales.

Separate cartons can use various auxiliary materials to combine small boxes on the basis of traditional standard box types, or use new molding methods.

New separated cartons generally use a combination of H-shaped middle partitions and rolled cartons.

There are two types of roll-wrapped cartons, N type and F type. Among them, type F is more popular and is mainly used for the outer packaging of shampoo and conditioner in plastic bottles and condiments in glass bottles.

The F-type roll-wrapped carton can decompose the original 20-bottle carton into two 10-bottle cartons. The compressive strength of the packaging is also improved, the cost of packaging materials is reduced, and it has a good promotional function.

Triangular prism type corrugated carton

Triangular prism type corrugated carton is a box body and a corner lining formed on one page. The four corners of the corrugated carton form a triangular prism or right-angled column structure, thereby improving the compressive strength. Increase 20%-50%.

Triangular prism cartons are available in pallet and sealed types, with a variety of box types to choose from. Compared with ordinary corrugated boxes, the compressive strength of triangular prism-type corrugated boxes can be increased by 20%-30% under standard conditions and 40%-60% under high humidity conditions; the box will not bulge and will not bulge under humid conditions. Especially obvious below; from a structural point of view, the corner parts are relatively strong, so the damage rate of the contents is extremely low when falling, impact and vibration; when a load is applied, the carton deforms stably and is not likely to cause stack collapse; the sales of pallet-type triangular column corrugated boxes Good displayability.
