Protective film has brought great convenience to our lives

The role of the polymer protective film is to protect the protected material from harmful gases and microorganisms during transportation, storage and processing. Especially in the bending and stamping process, it can effectively improve the gap between the material and the mold. Lubricity, improve the efficiency of processing operations, ensure the grade of products, reduce the consumption of raw materials, and increase the interests of the enterprise. The polymer protective film is the most common protective film on the market at present, and the remarkable feature of the protective film is that it is relatively hard and more resistant to damage. In addition, even if it is used for a long time, it will not turn yellow like PVC material. In the past, it generally relied on electrostatic adsorption, which was easy to foam and fall, but it can be reused by washing with the fallen water. The current protective film can also be pasted with an adhesive. There are usually two types of adhesion. Acrylic rubber has strong adhesion and silicone rubber has good high temperature resistance. In mass production, it is recommended to use a mechanical coating protective film commonly called a laminator. This is particularly useful if you need to accept protective films on both sides of the paper, because the machine can be applied to both sides at the same time.
