Nowadays, its social development is in the process of continuous progress, everyone's demand for the quality of its products in daily life is continuously improving, and its various new things are also continuously happening. PE protective film looks ordinary, but it also provides great convenience for people's lives.

Performance regulations of PE protective film.

1. The PE protective film is malleable to the surface of the protected raw material.。

2. PE protective film has excellent adhesion properties to the protected raw materials. During the loading, unloading and production of raw materials, the protective film is not easy to get up and fall off.。

3. The PE protective film has good aging resistance and adhesion reliability. After a few days or a long time, the detachment force does not increase significantly, and it is easy to remove. When removed, there are no glue stains on the protected surface. No stains.。

The paste between the PE protective film and the protected product is not firm, and it will fall off during transportation and use. The reason for this problem is the opposite of the previous problem. The big possibility is that the pressure-sensitive adhesive used in the production of the protective film product is not enough. There is also a possibility that the pressure of the mold press used by the user when applying the mold is not enough, or the surface of the profile is not clean, there is dust or paint, etc., which affects the pasting effect of the sensitive adhesive. If this problem occurs, we must take the right medicine for the cause, replace the sensitive adhesive to increase the film pressure, or pay attention to the profile when applying the film. The surface is effectively cleaned to avoid such problems.

The protective film performs well in the middle after being used for a period of time, but the wings are raised at both ends. The main reason for this phenomenon is that the protective film has a large degree of stretching during the pasting process with the protected profile. After the pasting is completed, in case of high temperature environment, unnecessary retraction occurs. This problem mostly occurs in the products of southern customers. Therefore, PE protective film should pay attention to the impact of environmental temperature difference on product use during the production process, and avoid unnecessary surface stretching during the pasting process.

What users report more is the degumming problem of the protective film product. This problem is reflected in the protective film of the profile. When the user tears the protective film off the surface of the profile after the installation and construction of the profile is completed, the viscose expressed by the protective film does not follow the protective film, but remains on the profile product. This is what users do not want to see, because it is very troublesome and requires someone to scrape off the glue from the profile, which is particularly labor-intensive and time-consuming.
