When you find that there is dust on the surface of the protective film, do not wash it with water, otherwise it will affect its adhesion, as long as it is treated with dry paper towels. Under normal circumstances, oil stains are the biggest opponent of the protective film. Once the oil stains are occupied, the protective film will not only lose its material, but also cannot protect the objects. Therefore, the pollution of oil stains must be absolutely prohibited.


Some protective films need to be isolated from the outside world when they are in use. This can be easily done with adhesive tape. Unless there are special materials on the surface of the protective film itself, only simple maintenance is enough.


When the user tears off the protective film from the surface of the profile after the installation and construction of the profile, the adhesive on the surface of the protective film does not follow the protective film, but remains on the profile product, which is the last thing the user wants to see. Because this is very troublesome, someone needs to scrape the glue off the profile. It takes a lot of work and time. There are many possibilities for this problem. The most likely is that the pressure glue used for the protective film product does not meet the regulations, that is, Too sticky, when the protective film product is peeled off, the external tension is greater than the internal stress, and it remains on the profile.





The protective film performs well in the middle after a period of use, 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 profile to be protected. In the high temperature environment, unnecessary shrinkage appears. This problem mostly occurs in the products of customers in the south. 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.


The adhesion between the protective film and the protected product is not strong, and the phenomenon of falling off occurs during transportation and use. The reason for this problem is the opposite of the previous one. The greatest possibility is that the protective film product is used when it is produced. The viscosity of the sensitive adhesive is not enough. Another possibility is 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, there is dust or paint, etc., which affects the adhesive effect of the sensitive adhesive. ! If this problem arises, 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 the occurrence of such problems.


If you encounter this kind of problem, you can use a clean cloth dipped in a little alcohol, and repeatedly wipe the remaining sensitive adhesive until the sensitive adhesive is wiped clean, but it is important to note that you should never wipe the adhesive. Too much force, otherwise it may affect the finish of the profile product.
