When in use, the release film layer 1 is removed, and then the explosion-proof film is adhered to the inner surface of the glass backboard through the adhesive layer 2. And finally, forming the corresponding pattern on the outer surface of the glass back plate in a laser engraving mode. After the laser penetrates through the glass back plate, the adhesive layer 2 and the base material layer 3, the electroplated layer 4 is carved into a pattern. Such as engraved bar codes, product LOGO, etc. At present, with the increase of consumer groups, the demand of the color value of a product is more and more strict, various color explosion-proof films are pursued by manufacturers, and a common coloring mode is that color master is usually added into glue or color is printed on a base material, so that a composite roller for thermocuring the water-soluble adhesive of the color explosion-proof film and a processing method of the film are provided.
