Hot stamping film refers to a technology that combines laser holographic electrochemical aluminum film with hot stamping technology to form colorful laser holographic logos and three-dimensional pattern anti-counterfeiting logos on the surface of printed matter.
This technology can add laser encryption and back anti-counterfeiting layer for anti-counterfeiting of documents, cards, bills, trademarks, etc.
If this anti-counterfeiting mark is added to the outer packaging of the product. Its anti-counterfeiting strength is unmatched by current single laser holographic anti-counterfeiting marks. In addition, special edition laser holographic electrochemical aluminum films can be produced for products according to the requirements of different users. Because the special edition pattern production includes the specific requirements of the merchants, it is also integrated with the ever-evolving laser holographic technology. Whether it is the anti-counterfeiting supply and marketing method of the special edition, or its decorative effect, it is superior.

The products involved mainly include: car signs, glasses frames, mobile phone case surfaces, stereos, Stationery boxes, various pen holders, etc.
3. Hot stamping foil for fabrics and clothing. Commonly used hot stamping foils on different fabrics, clothing, ready-made clothes, hats, socks, etc. There are also hot stamping foils that are never used for scarves. Hot stamping foil 4. Metal and glass hot stamping foil, commonly used for metal nameplates, nameplates as soon as possible, and hot stamping on the surface of glass cups, glass plates, glass bottles and other materials 5. Leather hot stamping foil, commonly used for PU leather, Genuine leather and more. Products involved include: fashion shoes, handbags, belts, book covers, etc. Structure The structure of hot stamping foil is divided into: base layer, peeling layer, color layer, electroplating layer and glue layer. The first layer: the base layer generally uses a 12μm-25μm thick biaxially stretched polyester film. Its main function is to support the coatings attached to it and facilitate continuous hot stamping during processing. It has properties such as stretch resistance and resistance to instantaneous high temperatures. The second layer: peeling layer is generally coated with organic silicone resin. The main function is to enable the color material, aluminum and adhesive layer to quickly separate from the polyester film after hot stamping and be transferred and bonded to the surface of the object being stamped. The release layer should have good shedding performance, otherwise the hot-stamped images and text will be blurred and blurry, affecting the quality of the hot-stamped products. The third layer: Color layer The main components are film-forming properties, heat resistance, transparency, suitable synthetic resins and dyes. Commonly used resins include polyurethane nitrocellulose, melamine formaldehyde resin, modified rosin resin, etc. During production, the resin and dye are dissolved in organic solvents to form a color paste, which is then coated and dried. It has two main functions: one is to display the color; the other is to protect the aluminum-plated graphics and text stamped on the surface of the item from being oxidized. The colors of electrochemical aluminum foil include golden, orange, gray, red, blue, green, etc. The color of the color layer is given luster after passing through the aluminum plating layer, and the color changes to a certain extent, such as yellow becoming gold after being plated with diamonds, gray becoming silver after being plated with aluminum, etc. The coating requirements for the color layer should be fine and without any small particles to avoid trachoma and the coating should be uniform.
The fourth layer: electroplating layer. Place the film coated with pigments in the vacuum chamber of the vacuum continuous aluminum plating machine. Under a certain degree of vacuum, through resistance heating, the aluminum wire is melted and continuously evaporated onto the color layer of the film. An aluminum plating layer is formed. The main function of the aluminum coating is to reflect light and change the color of the color layer to give it a metallic luster. Fifth layer: The glue layer is generally a fusible thermoplastic resin. Depending on the material being stamped, different resins can be used. The resin is dissolved in an organic solvent or made into an aqueous solution, and is coated on the aluminum layer through a coating machine. After drying, the glue layer is formed, and its main function is to bond the hot stamping material to the object being ironed. When hot stamping, one of the main reasons why the hot stamping does not go well is that the glue layer does not match. Different types of electrochemical aluminum foil should be used for different hot stamping objects. Types of hot stamping foil: 1. Paper hot stamping foil 2. Plastic hot stamping foil 3. Clothing and cloth hot stamping foil 4. Metal and glass hot stamping foil 5. Leather hot stamping foil How to use (1 ) Fabrics are flat ironed. Place the hot stamping paste on the screen printing screen. Use a squeegee to print the hot stamping paste onto the surface of the object (such as cloth, clothing, etc.). After the hot stamping paste dries, buckle the hot stamping paper on the surface of the fabric. 130 ~140℃, pressure 4kg/cm², time 10″ or more, take it out, and tear off the waste film after cooling.
(2) Flat ironing of leather products, the main tool is aluminum or copper hot stamping plate , suitable for hot stamping leather and other products. The pressure is smaller than that of fabric hot stamping, and the hot stamping time is shorter than that of fabric hot stamping. It can be flexibly controlled according to different products.
(3) Ribbon products are hot stamped and commonly used tools. : Silicone wheel, mostly used for hot stamping of trademark webbings
(4) Hot stamping on cloth products, often used for hot stamping on entire rolls of fabrics. The varieties are divided into special hot stamping and general hot stamping based on the hot stamping effect. . The types of hot stamping paper generally include: full transfer film, semi-transfer film, etc. The colors include: single color film, multi-color film, etc.,, Laser hot stamping film is a film delivery method for laser hot stamping film in the hot stamping process. , including the following steps in sequence: (1) Select the appropriate laser hot stamping film; (2) Determine the small step distance, the number of film feeding times for the small step distance, and the value of the large step distance; (3) Set the reference position; (4) Laser The hot stamping film pauses and proceeds to perform hot stamping; (5) After the hot stamping is completed, the film is fed in small steps, and at the same time, the counter accumulates the film feeding action in small steps; (6) The value in the counter is compared with the set small step Compare the distance and the number of times of film feeding to decide to turn to step (4) or step (7). When turning to step (7), the counter is cleared; (7) The laser hot stamping film pauses and advances and hot stamping is performed; (8) Hot stamping After completion, feed the film at a large distance; (9) Adjust the reference position; (10) Cycle through steps (4) to (9). This invention effectively prevents the seams of the laser stamping film from being stamped on the product. The hot stamping paper process uses the principle of hot press transfer to transfer the aluminum layer in anodized aluminum to the surface of the substrate to form a special metallic effect. The main material used for hot stamping is Electrochemical aluminum foil, so hot stamping is also called electrochemical aluminum foil. Electrochemical aluminum foil is usually composed of multiple layers of materials, and the base material is often PE, followed by a separation coating, a color coating, a metal coating (aluminized) and a glue coating. What is commonly used in the printing industry is to hot stamp electrochemical aluminum foil on paper, which is called hot stamping. Hot stamping is a general term for a process. Hot stamping does not mean that the hot stamping paper is gold? There are many kinds of hot stamping paper materials, including gold. , silver, laser gold, laser silver, black, red, green, etc. Note: Hot stamping film uses heat and pressure to transfer your pattern or text to the surface of the stamped material. You need to have a hot stamping machine. Then you need to make a plate (such as a lead plate, copper plate, etc.) with the text or pattern you want and heat it to the required temperature. Then put this product on it and apply appropriate pressure for 0.4-0.7 seconds. The exquisite patterns are vividly visible. It should be noted that when hot stamping different materials, you should choose the appropriate model of product, and select the appropriate temperature, pressure, and hot stamping time to achieve the ideal hot stamping effect. Storage method 1. Temperature 5℃-20℃; 2. Vertical placement is more appropriate; 3. Humidity 30-70%; 4. Moisture-proof and not exposed to sunlight.
