What problems will occur in the use of protective film?

- Jul 10, 2020-

Issue 1: The PE protective film is not firmly attached to the protected product

The phenomenon of shedding 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 adhesive used in the production of protective film products is not enough; there is another possibility that the user The pressure of the molding machine used when applying the mold is not enough, or the surface of the profile is not clean, there is dust or paint, etc., which affects the paste effect of the sensitive adhesive! If this problem occurs, it is necessary to address the cause, take the right medicine, replace the sensitive adhesive, 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.

Problem 2: Difficult peeling of PE protective film products

After the profile product is installed and peeled off, the protective film cannot be effectively peeled off. The reasons are two possibilities. First, the sensitive adhesive used in the protective film product is not a special sensitive adhesive for the protective film. If so, when the protective film is pasted 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 used in the protective film itself is too soft. , It can't bear the pulling force during peeling, and it breaks during peeling, which is a problem that makes users very headache.

Problem three: PE protective film performs well in the middle after a period of use, but the two ends are winged

The main reason for this phenomenon is that the protective film is stretched to a large extent during the pasting process of the protected profile. After the post is applied, it will encounter unnecessary retraction in high temperature environments. This problem occurs mostly in For the products of customers in the south, the PE protective film should pay attention to the impact of the environmental temperature difference on the product use during the production process, and avoid unnecessary surface stretching during the pasting process.

Question 4: The most reflected by users is the degumming of PE protective film products

This problem is most reflected in the profile protection film. When the user tears the protection film off from the profile surface after the profile installation is completed, the viscose expressed by the protection film does not follow the protection film, but remains on the profile product This is the last thing users want to see, because it is very troublesome and requires someone to remove these glues from the profile, which takes a lot of time and labor.https://www.pe-protectionfilm.com/
