UV invisible fluorescent anti-counterfeiting film refers to the process of pre-gluing and rewinding the plastic film, and then compounding it with paper printing.
First, the pre-coating film processing plant will apply the glue on the film and rewind the film according to the specifications and format used by the pre-coating film processing plant.
Laminating is the processing technology of coating plastic film with adhesive and bonding it with paper printed matter after heating and pressing to form a paper-plastic composite product.
Under ordinary light, the coated printed matter has a thin and transparent plastic film on the surface, and the surface is smoother and brighter, thereby improving the gloss and fastness of the printed matter, and the graphics and text colors are more vivid and three-dimensional.
At the same time, it also plays a role in waterproof, anti-fouling, abrasion resistance, folding resistance, and chemical corrosion resistance.
Under UV light, it can be displayed in different colors, which has the effect of anti-counterfeiting. You can choose multiple colors.
Product Name: UV Invisible Security Film
Film thickness: 0.01-0.02mm
Properties: Good light resistance
Process:
⑴The thickness of the film is between 0.01-0.02mm. After corona or other treatments, the surface tension should reach 4.0 x 10-2N/m in order to have better wetting performance and adhesion performance.
⑵The treatment effect of the film corona treatment surface is uniform, the higher the transparency, the better, to ensure the best clarity of the printed matter covered.
⑶The film should have good light resistance, not easy to change color under long-term exposure to light, and keep the geometric size
Stable.
⑷The film should be in contact with solvents, adhesives, inks and other chemical substances, and the film should have a certain degree of chemical stability.
⑸ The appearance of the film should be smooth, without unevenness and wrinkles, without bubbles, shrinkage, pitting and other defects.
The UV invisible fluorescent anti-counterfeiting film is composed of a substrate and an adhesive layer. The substrate is usually a polyester (PET) film and a biaxially oriented polypropylene (BOPP) film. BOPP film has the characteristics of high transparency, good brightness, non-toxic and odorless, water resistance, heat resistance, low price, and soft texture. It is an ideal material in the laminating process. Its thickness is about 12-20um. Therefore, from the cost of materials Considering the processing technology, most of the pre-coated film substrates use BOPP film.
