1. Different properties: cold laminating film is made of transparent PVC through adhesive processing. Plastic packaging film needs to be used with the plastic packaging machine for heating. Different thicknesses need to refer to different plastic packaging temperatures, which are related to the pressure and speed of the plastic packaging machine and the thickness of the plastic packaging film. The laminating process of heat-laminating laminating machine is not a new thing, the machine has been widely used in the printing industry.
2. Different features: cold laminating film can increase the texture of the picture, and protect the picture, scratch and water resistance. Before plastic packaging film is used, cut out a suitable plastic packaging paper according to the size of the paper to be plasticized. The heat-laminated film can protect the paper by using the coating film as the cover.
3. The effect is different: After the plastic film is heated, the paper to be plasticized is sealed and wrapped by the plastic paper (because the two opposite surfaces of the plastic paper are glued, they will be bonded after heating), so that it can be waterproof to a certain degree and used for extended use life. The cold lamination film can prevent the screen (printing surface) from being scratched, polluted or wet, and protect the screen.
