During the investigation, users of PE protective film have reported numerous quality issues with the film to us, hoping for timely resolution of these concerns. However, each user encounters different problems with PE protective film, and targeted analysis is required before formulating solutions.
Issue with Poor Adhesion of PE Protective Film
The most likely cause of such issues is the insufficient adhesion of the pressure-sensitive adhesive in the PE protective film, or insufficient pressure reaching the standard, inadequate cleanliness of the adhesive surface, etc. To address these, the higher-level solution is to replace the pressure-sensitive adhesive or adjust the film pressure, thereby preventing similar issues from recurring.
2. Issue of PE protective film curling at both ends in later stages of use
Generally, issues with excessive stretching of PE protective film only arise after exposure to high temperatures, highlighting the significant impact of environmental temperature on the quality of PE protective film adhesion.
Issue with PE Protective Film Adhesion
This is a common issue manifestation, meaning that when the protective film is peeled off from the profile surface, adhesive residue from the film remains on the profile product.
If users encounter this issue, they can use a clean cloth dipped in a small amount of alcohol to repeatedly wipe away the residual adhesive until it is completely clean. However, they should not apply too much force to avoid affecting the surface of the material.
Issue with Difficulty in Stripping PE Protective Film
This issue stems from two main causes: one is that the adhesive used may not be suitable for the protective film, and the other is that the material of the protective film's backing tape is too soft, unable to withstand the tension during peeling. To resolve this, a fundamental approach is required, either by replacing the pressure-sensitive adhesive or by changing the material of the protective film backing tape.
