Now introduce the common problems and solutions during the use of PET protective film:

1. In the process of transportation and use, the PET protective film and the product to be protected are not firmly pasted and fall off. , This is because the viscosity of the sensitive adhesive used in the production of PET protective film products is not enough. There is also a possibility that the pressure of the press molding machine used by the user is not enough when the mold is applied, or the surface of the profile is not clean. Dust or paint, etc., affect the paste effect of the sensitive adhesive! If this problem occurs, you must address the cause, prescribe 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 applying the film to avoid this The emergence of similar problems.

Good stability, viscosity is not easy to change after high and low temperature, no bubbles in appearance, easy to cut and punch without leaving glue residue.

2. After a period of use, the PET protective film will wing on both ends. The main reason for this phenomenon is that the protective film stretches to a large extent during the pasting process with the profile to be protected. In the environment, unnecessary shrinkage has occurred. This problem mostly occurs in the products of southern customers. Therefore, in the production process of PET protective film, you should pay attention to the impact of environmental temperature differences on the use of products, and avoid unnecessary use during the pasting process. Surface stretch.

3. PET protective film will have degumming problem. This problem is most reflected in the profile protective film. When the user tears off the protective film from the surface of the profile after the installation and construction of the profile, the adhesive performance of the protective film does not follow the protection The film is left on the profile product. This is the last thing users want to see, because it is very troublesome and requires someone to cut the glue off the profile, which is particularly labor-intensive and time-consuming. There are many possibilities for this problem. The most likely reason is that the pressure glue used for the protective film product does not meet the requirements, that is, it is too sticky. When the PE protective film product is peeled, the external tension is greater than the internal female force, and it remains on the profile. If the user has this kind of problem, he can use a clean cloth dipped in a little alcohol to wipe the remaining sensitive adhesive repeatedly until the sensitive adhesive is wiped clean. However, it should be noted that you must not too much during the wipe. Use force, otherwise it may affect the finish of the profile product.
