Hot laminating film is a physical and thermal property that forms a molten state in a high-temperature environment. After cooling treatment, it forms a sealed layer of protective space. The hot lamination film needs to go through both hot and cold processes can be formed and can maintain a stable effect for a long time, but due to the complexity of the process, specialized machines must be used to make it, which is a general method so the cost is relatively high.

Hot laminating film refers to the process of gluing and rewinding plastic film in advance, and then compounding with paper printing. It is first coated by the pre-coated film processing plant according to the use of specifications, format, the adhesive liquid is coated on the film after rewinding for the use of manufacturers to choose, and then with the printed matter composite/laminating/that is, the film is coated with adhesive, and paper printed matter after heating, pressurizing to make it bonded together, forming a paper-plastic product processing technology. The coated printed matter, due to the surface of a thin and transparent film, the surface is smoother and brighter, thereby improving the gloss and fastness of the printed matter, the graphic color is more vivid, full of three-dimensional sense, and it also plays a role in waterproof, anti-fouling, wear resistance, folding resistance, chemical corrosion resistance and so on.
Product Introduction:
1. the coating process does not need to use solvents, eliminate the use and storage of flammable solvents caused by fire hazards, no benzene and other polluting substances and gas emissions, so non-toxic, tasteless, can be in contact with food, in line with food hygiene standards, is in line with the international trend of environmental protection coating (laminating) products.
2. compared with the solvent-based coating process, the use of this product can make the printed matter smooth and bright, bright color. Due to the higher bonding strength, it can effectively prevent the printing in stamping, concave and convex bubbles and film removal, etc., after the film can be UV, hot stamping and other processes, widely used in wine boxes, cosmetics boxes, hand bags and other printed matter packaging.
3.compared with the traditional ordinary film laminating process, the operation is simpler: no gluing, gluing, drying and other procedures, only the hot roller temperature can meet the requirements, no additional equipment, with better film quality, more environmentally friendly, safer, more efficient and other advantages. Material: BOPP base film +EVA adhesive layer
Features: strong softness and flatness, environmental hygiene, low density, good transparency, strong chemical resistance, low temperature overlay, stable ink color after composite. Among them, the light film is transparent and glossy, and the color sense is obviously enhanced after compounding; Matte film can dull and retain color.
Advantages of using Hot laminating film:
1. the coating process does not need to use solvents, non-toxic, tasteless, is environmentally friendly laminating (laminating) products.
2.the use of hot pressing film coating can make the printed matter smooth and bright, bright color. The adhesive strength is higher, effectively prevent the print in stamping, concave and convex bubbles and film off, after the film can be UV, hot stamping, widely used in wine box, cosmetic box, hand bag and other printed matter film.
3. the operation is simpler, no need to adjust glue, glue, drying and other procedures, only the temperature and pressure of the hot roller can meet the requirements, with better film quality, more environmental protection, safer, higher efficiency and other advantages.

Length: 100 to 3000M
Paper Core Diameter: 25.4mm (1 inch), 58mm (2.25inches), 76mm (3 inches)
Application parameters of hot laminating film
Laminating equipment: dry, wet heating laminating machine Heat sealing temperature: 95~105℃ (measured temperature) Heat sealing pressure: 10-20Mpa speed: 8-20 m/min
Instructions For Use
Can be combined in the temperature range of 95~105℃, the final effect is also different by the type of paper.
About 70% of the maximum bond strength can be achieved immediately after the double abdomen, and the maximum bond strength can be reached one week later.
If it is necessary to make a beer line stamping, it is recommended to conduct a small batch test to determine the effect.
Determine the maximum bonding strength before use, because of the combination of different paper ink, the effect is different.
If the ink on the surface of the printed matter is not completely dry, it will cause film stripping. It is recommended to ensure that the ink is completely dry to ensure quality.
The film is bonded at low temperatures during production, so it is not stored at high temperatures or placed horizontally.

If Using:
1. Turn the pressure regulator handle on the box on both sides of the cold press machine, separate the upper and lower two axes, put the picture to be mounted and the cold press film into the two axes at the same time, turn the pressure regulator handle, so that the upper axis moves parallel down, when the pressure regulator handle feels suddenly relaxed, it means that the upper and lower two axes have been in contact, please do not continue to press down. Simply tighten the pressure regulator gently. If the pressure continues, the shaft will be deformed and the operation will fail
2. After the pressure is adjusted, the graph between the two axes and the cold-pressed film are withdrawn from between the two axes. Prepare to press the film.
Cold Laminated Film Common Question Treatment
Question 1. When a large area of the screen has the feeling of "fog"
1. Insufficient film pressure -- adjust the pressure of the cold mounting machine;
2. The two ends of the cold laminating machine are not smooth -- adjust the adjusting screws of the distance between the cold laminating machines to achieve equal distance;
3. Over-photo paper - the surface of the photo paper is uneven, generally about 25 degrees, placed 2-3 hours will automatically disappear, the higher the temperature will disappear faster;
4. Over PP glue --A. hand touch PP glue screen if there is no "rough" feeling, then according to the above method; B. There is a "rough" feeling that requires more PP backing glue;
5. Glue viscosity is not good at low temperature --A. Improve the use of ambient temperature. B. Replace the cold mounting film
Question 2. When there is a "white spot" behind the screen
1. The glue is not sticky enough --A. Increase the ambient temperature,B. Replace the cold mounting film;
2. Thin glue - the general distance is not long, the probability of greater before and after shutdown, generally pull off a few meters;
3.PP adhesive surface hand touch "rough" feeling --A. Replace PP adhesive,B. Or use studio film over the picture;
4. There is dust in the air --A. Purify the operating environment,B. Close the blower or air inlet source;
5. Water droplets (such as saliva) inadvertently splash on the surface of the spray painting --A. Pay attention when operating, especially when speaking, do not face the picture,B. Air temperature in dry environment, such as air conditioning, hot fan or ventilation.
Question 3. When there are "bubbles" immediately after painting
1. The glue does not "mature" -- change the cold mounting film
Question 4. It is fine after painting, but there are "bubbles" after leaving it for a while (or the next day).
1. The glue is not "matured" thoroughly -- open the cold mounting film
Pack and place in the air for 2-5 days to allow the glue to fully "mature" under natural conditions;
2. The picture is not sufficiently dry, especially in winter, because there are antifreeze components in the winter ink, which is not easy to volatilize completely.- Let the picture be fully dry, the general winter time is twice as long as summer and autumn above, and then over the painting (must pay attention to dust);
3. Large area single color such as: all black/all red, etc. --A. Light color,B. Replace ink,C. Fully dry the picture (completely dry),D. heat the picture,E. replace the more viscous cold mounting film, the thinner the better.
4. The ambient temperature is low, so that the cold laminating film surface is too hard -- improve the ambient temperature when using;
5. Cold mounting film is too thick -- replace it with a thin cold mounting film;
6. Roll up immediately after painting, the glue and the picture are not fully integrated - after painting, place it flat for more than 45 minutes and then roll it up.
7. Aging glue -- Replace the cold mounting film.
