What Are the Types of Protective Film and the Five Major Problems?

1. What are the types of protective film?

There are many types ofprotective films. According to the materials, they are commonly used: PE (polyethylene), PET (polyester film), CPP (polypropylene), PVC (polyvinyl chloride), OPP, etc., the color of PE. Many, the most commonly used are transparent, blue, black and white, milky white, in addition to black, gray, green, yellow, orange, gold, red and so on. Generally, products with smooth surface can choose electrostatic film, low-viscosity PE plain or reticulated film. The rougher the surface, the higher the viscosity of the protective film. For general screen protection, choose PET protective film, various plastic products and plates, and glass surface protection choose PE film. High-gloss plastic surface can use electrostatic film, matte film, and low-viscosity PE film.

Pe Protective Film

Second, the five major problems in the application of protective film?

1. The PE protective film is not firmly adhered to the product being protected, and the phenomenon of peeling occurs during transportation and use. The reason for this problem is exactly the opposite of the previous problem. The biggest possibility is protection The viscosity of the sensitive adhesive used in the production of the film product is insufficient.

2. The peeling of the protective film product is difficult. When the profile product is installed and peeled off, the protective film cannot be effectively peeled. There are two reasons for this. Of course, the protective film is very effective when it is pasted, but it will be very difficult to peel off. This is also the most common problem of protective films produced by some illegal protective film product manufacturers.

3. The protective film performs well in the middle after being used for a period of time, but the two ends are winged up. The main reason for this phenomenon is that the protective film is more stretched during the pasting process with the protected profile. In the case of high temperature, unnecessary shrinkage occurred.

4. The problem of degumming of the protective film product. This problem is reflected most in the protective film of the profile. When the user tears off the protective film from the surface of the profile after the installation and construction of the profile, the adhesive of the protective film does not follow the protective film. , But left on the profile products, which is the last thing users want to see,

5. Although the protective film product can be effectively peeled off, there is a protective film expression on the surface of the profile. This problem often occurs on some low-level protective film products. This is because the protective film is combined with the protected profile when it is In a suitable environment such as sunlight and moisture, a kind of chemical cooperation occurs.
