PE protective film, about this kind of protective film, how should we treat it? Although PE protective film has many advantages, there is no perfect thing in the world, so for PE protective film, is there any defect? This is also what we are puzzled about, so it leads to the main content of the article, which is the quality problems of PE protective film.


Problem 1: the PE protective film is not firmly pasted between the protected products, which causes the PE protective film to fall off during the transportation or use of the protected products.



There are two reasons. One is that the viscosity of the sensitive adhesive used in the production process of PE protective film is not enough, so the degree of adhesion is not enough; the other is that the pressure of the film press is not enough, or the surface to be pasted is not cleaned, thus affecting the pasting effect. Therefore, the solution is to change the sensitive adhesive, increase the pressure of the film, and clean the surface thoroughly and effectively.


Problem 2: after the protective film is used for a period of time, the two ends of the protective film are warped.



The reason is that the protective film has a great stretch in the process of pasting with the surface to be pasted. After sticking it, it will be retracted in high temperature environment. Therefore, in the process of pasting, it is necessary to avoid unnecessary stretching and pay attention to the environmental temperature difference when using.


Problem 3: degumming of protective film.



When the protective film is torn off, the adhesive is not torn off together, but left on the surface to be pasted. The reason is that the pressure glue used for the protective film does not meet the requirements, and the viscosity is too sticky. The solution is to use the pressure glue that meets the specified requirements, so that its viscosity is moderate. Once this happens, we can dip a small amount of alcohol into a clean cloth and wipe the surface repeatedly with light force until it is cleaned.


Problem 4: Although PE protective film can effectively peel off the surface, it is not clean and has residues.



This phenomenon often occurs in low-grade protective film products, because the protective film combines with the protected object. At present, there is no good solution to avoid this phenomeno.
