What are some common quality problems with PE protective films?

Polyethylene (PE) protective films are widely used in various applications that provide more protection to surfaces. Although the quality of PE protective films is improving, some of them may face certain issues. Therefore, industries should know some common quality problems of PE protective films with attention to detail. This will help to overcome them effectively during the installation process. Moreover, users can avoid unwanted issues to ensure the best results and experience peace of mind.

How to know some common quality problems with PE protective films?

1. Adhesive residue

It is one of the most common quality problems faced by users after purchasing PE protective films. The issue often occurs on profile protective films when a user removes them from the profile after the installation, and the adhesive residue will remain on the profile product for a long time. Removing the adhesive residue needs special measures, which is time-consuming, and several factors are responsible for the problem. However, the major reason is that the PSA (pressure-sensitive adhesive) used in the film doesn’t meet the specifications.

2. Difficulty peeling off the protective films

Users may face difficulties peeling off the protective films after installing them on a profile product. The problem occurs due to two possibilities. First, the pressure-sensitive adhesives in PE protective films are not properly designed for them. Secondly, the material used in the protective film master tapes is soft enough to withstand peeling.

3. Adhesion issue that results in detachment

Sometimes, PE protective films can lead to detachment when they do not adhere properly to a protected product. This happens due to the lower viscosity of pressure-sensitive adhesives used in PE protective films. The films need enough pressure, and the problem occurs when users don’t apply the right pressure. Furthermore, a profile surface should be free from dust and other contaminants because they will affect the bonding process.

4. Both ends of the protective films are tilted

The user should ensure that they don’t stretch PE protective films extensively while installing them on a protected profile. This is because it will lead to shrinkage, and the issue occurs in subtropical regions that have high-temperature environments after the installation process. An industry should pay attention to the impact of environmental factors to avoid unnecessary surface stretching.

5. Protective film degumming problem

Degumming is another common problem faced by users after installing protective films on a profile. It happens when the peeled-off PE protective films are left on the product. The reason for the issue is that the pressure glue used for the films does not meet the standards. Those who face the problem should use a clean cloth with a dip in a little alcohol to help remove the remaining sensitive adhesives. On the other hand, users shouldn’t apply too much force while wiping them off.

Where to buy the best PE protective films?

Industries should pick a reputed manufacturer when they want to buy the best PE protective films. They should read reviews of PE protective film manufacturers online to select the right one that satisfies their needs.
