Problem 1: The adhesion between the PE protective film and the protected product is not strong, and it will fall off during transportation and use. The most likely cause of this problem is the pressure-sensitive adhesive used in the production of the protective film product. If the degree is not enough, there is another possibility that the pressure of the press molding machine used by the user is not enough when the user is performing the mold, or the surface of the profile is not clean, there is dust or paint, etc., which affects the paste effect of the sensitive adhesive! If this problem occurs, it is necessary to address the cause, prescribe the right medicine, replace the sensitive adhesive to 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 such problems.

Problem 2: The protective film performs well in the middle after using it for a period of time, but the two ends are winged. The main reason for this phenomenon is that the protective film stretches to a large extent during the pasting process with the protected profile. In the future, in the high temperature environment, unnecessary shrinkage occurred. This problem mostly occurred in the products of southern customers. Therefore, the PE protective film should pay attention to the impact of the environmental temperature difference on the use of the product during the pasting process. Avoid unnecessary surface stretching.

Question 3: The problem that users complain most is the degumming problem of protective film products. 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 of the profile, the adhesive performance of the protective film It does not follow the protective film, but remains on the profile product. This is the last thing users want to see, because it is very troublesome and requires someone to scrape the glue off the profile, which is particularly labor-intensive and time-consuming. There are many possibilities for the problem. The most likely one 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 off, the external tension is greater than the internal stress, 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, but 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.

Problem 4: The protective film product is difficult to peel off. When the profile product is installed and peeled off, the protective film cannot be peeled off effectively. There are two possible reasons. One is that the sensitive adhesive used in the protective film product is not a special sensitive adhesive for the protective film. In this case, the protective film is of course very effective when it is pasted, but it will be very difficult to peel off. This is also the most common problem with the protective film produced by some illegal protective film product manufacturers. There is also a possibility The material used in the protective film master tape is too soft to withstand the tensile force during peeling, and breakage occurs during peeling, which is a very headache for users.

Question 5: Although PE protective film products can be effectively peeled off, there are protective film performance words remaining on the surface of the profile. This problem often occurs on some low-grade protective film products. This is because the protective film is combined with the profile to be protected. When there is a suitable environment such as sunlight and water, a chemical reaction occurs
