Analysis and solutions of various problems of PE protective film

During the investigation, the users of PE protective film reported to us a lot of quality problems about the protective film, and we hope that these problems can be solved in time. However, the problems of PE protective film encountered by each user are different, and a plan can only be formulated after a targeted analysis. 1. The problem of poor adhesion of PE protective film This problem is likely to be that the pressure-sensitive adhesive of the PE protective film is not viscous enough, or the pressure is not up to the standard, the cleanliness of the pasting surface is not enough, and so on. According to these circumstances, the higher solution is to replace the pressure-sensitive adhesive or film pressure to avoid similar problems. 2. The problem of warping at both ends of the PE protective film in the later stage of use generally occurs only when the PE protective film is stretched too much and encounters high temperatures. It can be seen that the environmental temperature has a great influence on the quality of the PE protective film pasting. of. 3. The problem of difficult peeling of PE protective film There are two reasons for this problem. On the one hand, the sensitive adhesive used may not be a special sensitive adhesive for protective film. On the other hand, the material used for the protective film master tape is too soft to withstand peeling. If you want to solve it, you can only start from the root, either replace the pressure-sensitive adhesive, or replace the material of the protective film master tape. 4. PE protective film degumming problem This is a very common problem, that is to say, when the protective film is torn off from the surface of the profile, the viscose of the protective film remains on the profile product. If the user has this kind of problem, you can use a clean cloth to dip a little alcohol and wipe the residual sensitive adhesive repeatedly until the sensitive adhesive is wiped clean. But don't use too much force, so as not to affect the surface of the material. The above is the content explained today, I hope it can help you.
