Problem analysis and solution of PE heat shrinkable film

During the investigation, PE heat shrinkable film manufacturers have received many problems related to the quality of the shrinkable film. It is expected that these problems will be solved in time. Each user encounters various PE heat shrinkable film problems, and target analysis is required to formulate a plan. 1. The safety problem of PE heat shrinkable film sticking is mainly caused by insufficient viscosity of the viscous agent of the PE protective film, insufficient pressure, and insufficient cleanliness of the sticking surface. According to this situation, you can replace the pressure-sensitive adhesive or apply film pressure to avoid similar problems. 2. The problem of warpage at both ends of the PE heat shrinkable film in the later period of use. Usually, high temperature will only be encountered when the PE protective film is increased too much, so you can see that the ambient temperature has a great influence on the bonding quality of the PE protective film . 3. The problem of degumming of PE heat shrinkable film is a very common problem. In other words, when the protective film is pulled away from the contoured surface, the glue represented by the protective film will remain on the contoured product. If this kind of problem occurs, put a little wine on a clean cloth and wipe off the remaining rubber. Don't use too much force, so as not to affect the material surface.
