PVC film popular science hot stamping film.

The hot stamping film of PVC film is also called anodized aluminum (the name of anodized aluminum is more used in the printing industry), which is a hot stamping made by adding a layer of metal foil to the film base by coating and vacuum evaporation. material. The thickness of anodized aluminum is generally (12, 16, 18, 20) μm, 500-1500mm wide. The electrochemical aluminum foil is made by coating the release layer and the color layer on the film sheet, then coating the glue layer by vacuum aluminum plating, and finally through the rewinding of the finished product. The domestic electrochemical aluminum foil is generally 4~5 layers. In China, 16μm thick biaxially stretched polyester film is generally used; the main function is to support the coating attached to the top and facilitate continuous movement during hot stamping. This means that the base film layer cannot be deformed due to temperature rise during the hot stamping process, and should have high strength, tensile strength, and high temperature resistance.

Generally, it is mainly coated with silicone resin. The main component of the second release layer in the anodized aluminum foil is silicone resin. Its main function is to make the color, aluminum, and adhesive layer quickly release after hot stamping, whether it is heating or pressing The film is transferred and bonded on the surface of the hot-stamped object, which means that there is a release layer in the electrochemical aluminum and the composition, and a chemical substance (silicone resin) is contained in the release layer. The main purpose is to help the material transfer well, and the finished hot stamping materials that we have made are mainly used to stamp all kinds of hot stamping materials on various items, and achieve printing on them. Effect. The main component in the base film layer is (polyester film). It is mainly used to prevent the stretching and change during the hot stamping process, so that the hot stamping process is intact. The slightest change will not occur due to high temperature. And high strength, high temperature resistance, tensile strength and other properties. The release layer must have better release performance, otherwise it will make the image and text after the hot stamping blurred, showing the bottom of the flower, and affecting the quality of the hot stamping product.
