The first is in the field of anodized aluminum hot stamping. As a special printing process that does not use ink, it uses a certain pressure and temperature to achieve its purpose. Therefore, it is necessary to install a high temperature resistant protective film (also known as a printed protective film) on the template and top of the hot stamping machine. Make the print and hot stamping foil squeeze each other in a short time.


In order to improve the packaging effect and barrier performance, achieve complementary performance and meet the needs of sealing, spray-painted composite films are often used as packaging materials, and the composite films here are actually high-temperature resistant protective films. At the same time, a high temperature resistant protective film is also used in the vacuum aluminum plating film. Only a very thin layer of metallic aluminum is vapor-deposited on the surface to form a vacuum aluminized film, which gives the film surface a metallic luster and greatly improves its barrier properties.






We are also familiar with card protective film, which is also made of high temperature protective film as the base material, and is extruded and coated with a layer of heat-sealable hot melt adhesive. High temperature protective film is widely used in the protection of various documents including ID cards, archives, photos and other surfaces.


At present, the high-temperature resistant protective film can also be used in the production of laser holographic anti-counterfeiting film in daily life, and a pattern logo that can be displayed by laser can be printed on the surface. The logo is mainly used for anti-counterfeiting on various items, so as to avoid counterfeiting effect.
