Poor quality of PET protective film can cause some situations. For example, the pressure-sensitive adhesive used in the protective film does not meet the requirements. It fails to meet the technical requirements in terms of formula and process implementation. Make the peeling force greater than the cohesive force; the corona strength of the base material used in the protective film does not meet the requirements. Generally, the surface tension of the substrate is required to be between 3840dyn. If it is too small, the peeling force of the protective film will be greater than the adhesive force and cause degumming. If this kind of problem occurs, it is recommended that the profile manufacturer do the following: Use a clean cloth dipped in an appropriate amount of organic solvents such as ethanol, ethyl ester, toluene, etc. to wipe. This sometimes brings about a problem, that is, the surface finish of the profile will be damaged to a certain extent after wiping with a solvent. Remedy: You can wipe it several times with a soft dry cloth to restore the finish.
