Now in the market, the role of PE protective film has been widely known, which mainly plays a very good protective role in the production and transportation of products. Therefore, it is widely used in various electronic products, hardware machinery, wire and cable industries. However, in practical application, due to different manufacturers, differences in product quality or incorrect use methods, PE protective film often has some problems. Xiaobian briefly introduces the five problems existing in PE protective film.

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

Falling off occurs during transportation and use. The reason for this problem is just the opposite. The biggest possibility is that the sensitive adhesive viscosity used in the production of protective film products is not enough; Another possibility is that the pressure of the die press used by the user when pasting the mold is not enough, or the surface of the profile is not clean, there is dust or paint, which affects the pasting effect of the sensitive adhesive! If this problem occurs, it is necessary to apply the right medicine to the case, replace the sensitive adhesive, increase the film pressure, or pay attention to the effective cleaning of the surface of the profile when applying the film, so as to avoid such problems.

Problem 2: difficult stripping of PE protective film products

When the profile products are stripped after installation, the protective film cannot be effectively stripped. There are two possibilities. One is that the sensitive adhesive used in the protective film products is not the special sensitive adhesive for the protective film. If so, the protective film has a very good effect when pasting, but it will be very difficult when stripping. This is also the most common problem of the protective film produced by some illegal protective film manufacturers, Another possibility is that the material used in the protective film itself is too soft to bear the tensile force during stripping, and there is fracture during stripping, which is a headache for users.

Problem 3: PE protective film performs well in the middle after being used for a period of time, but the wings rise at both ends

The main reason for this problem is that there is too much temperature difference between the product and the environment during the production process. Therefore, the main reason for this problem is that the product is not necessary to protect the environment during the stretching process. This problem should be avoided in the process of drawing and pasting the PE film.

Question 4: the most common problem reported by users is the degumming of PE protective film products

This problem is most reflected in the profile protective film. When the user tears the protective film off the profile surface after the installation and construction of the profile, the adhesive represented by the protective film does not follow the protective film, but remains on the profile products, which is the last thing the user wants to see, because it is very troublesome and requires a special person to cut these glue off the profile, which is particularly labor-consuming and time-consuming.
