The problem of shedding of PET protective film during use

PET protective film is currently the most common protective film on the market. It has a relatively hard texture and is relatively scratch-resistant. And it will not turn yellow and oily like PVC materials after long-term use. Therefore, it is widely used in digital product protection, automobiles, etc. , mobile phones and other fields.
So, do you know how to solve the shedding problem of PET protective film during use?
During transportation and use, the adhesion between the PET protective film and the product to be protected is not firm and may fall off. This is due to the insufficient viscosity of the sensitive adhesive used in the production of PET protective film products. Another possibility is that the pressure of the compression molding machine used by the user is not enough when the mold is attached, or the surface of the profile is not clean and dusty. Or paint, etc., which affect the sticking effect of sensitive glue. If this problem occurs, it is necessary to address the cause, prescribe the right medicine, replace the sensitive glue, increase the pressure of the film, or pay attention to effectively cleaning the surface of the profile when the film is applied, so as to avoid such problems. Good stability, the viscosity is not easy to change after high and low temperature, no bubbles in appearance, easy to shear and punch without leaving glue residue.
