What will happen to the protective film in use?

Nowadays, the role of PE protective film has been widely known. It mainly protects the product during the production and transportation of the product. Therefore, it is widely used in various electronic products, hardware machinery, wire and cable industries. However, in actual applications, due to different manufacturers, product quality differences, or incorrect usage methods, PE protective films often have some problems. Briefly introduce the five major problems of PE protective film.

Problem 1: Adhesion between PE protective film and the protected product is not firm

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 that the viscosity of the sensitive adhesive used in the production of the protective film product is not enough; there is also a possibility that the user When applying the die, the pressure of the stamping machine is not enough, or the surface of the profile is not clean, dust or paint, etc., which affects the adhesive effect of the adhesive! If this problem occurs, it is necessary to address the cause, prescribe the right medicine, and replace the sensitive Glue, increase the pressure of the film, or pay attention to the effective cleaning of the surface of the profile when filming to avoid such problems.

Question 2: Peeling of PE protective film products is difficult

When the profile product is installed and peeled off, the protective film cannot be effectively peeled. There are two reasons for this. One is that the sensitive adhesive used in the protective film product is not a special sensitive adhesive for the protective film. If this is the case, the protective film Of course, the effect is very good, 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. There is also a possibility that the material of the protective film itself is too soft Can not withstand the pulling force during peeling, and the phenomenon of breakage occurs during peeling, which is a very headache for users.

Question 3: After a period of use, the PE protective film performs well in the middle, but the wings end up

The main reason for this phenomenon is that the protective film has a large degree of stretching during the bonding process with the protected profile. After it is attached, it encounters an unnecessary shrinkage phenomenon in a high temperature environment. This problem often occurs in For the products of customers in the south, PE protective film should pay attention to the impact of environmental temperature differences on the use of the product during the production process, and avoid unnecessary surface stretching during the pasting process.

Question 4: The most frequently reported problem is the degumming of PE protective film products.

This problem is reflected most in the protective film of the profile. When the user tears the protective film from the surface of the profile after the installation and construction of the profile is completed, the adhesive of the protective film does not follow the protective film, but remains on the profile product. This is the last thing users want to see, because it's very troublesome and requires someone to remove these glues from the profile, which is very labor-intensive and time-consuming.
