Problems in the use of PE protective film

- Dec 12, 2020-

1. There is a problem of degumming

When the film is torn from the surface of the profile, the adhesive will remain on the profile product. This phenomenon is very common. If the user has this problem, a clean cloth can be moistened with a small amount of alcohol, and the remaining sensitive adhesive can be wiped repeatedly until all the sensitive adhesive is wiped. However, do not use too much force, so as not to affect the surface of the material.

2. Difficulty in stripping

There are two main reasons. On the one hand, the sensitive adhesive used is not necessarily a special sensitive adhesive; on the other hand, the material used in the protective film master tape is too soft to withstand the pulling force during peeling. In order to solve this kind of problem, we can only start from the root, need to replace the pressure-sensitive adhesive, or replace the master tape material.

3. The problem of not sticking firmly

The main reason for this kind of problem may be insufficient viscosity of the pressure-sensitive adhesive, or the pressure is not up to the standard, and the bonding surface is not clean enough. In this case, the pressure-sensitive adhesive or film pressure needs to be replaced to avoid similar problems.

4. The problem of using the back end to lift

Usually it only appears after the film is stretched excessively and encounters high temperatures. It can be seen that the ambient temperature has a great influence on the quality of the paste. In this case, users are required to avoid placing the profile in a high temperature and humid environment for a long time, and try to place it in a cool and dry place to prevent the problem of rear end tilting.
