The reason for this problem is just the opposite of the previous one. The biggest possibility is the viscosity of the sensitive adhesive used in the production of the polymer protective film product. Not enough, there is another possibility that the pressure of the press molding machine used by the user is not enough when performing the stamping, or the surface of the profile is not clean, there is dust or paint, etc., which affects the adhesive effect of the sensitive adhesive. In order to save this problem, you can use a clean cloth dipped in a little alcohol, and repeatedly wipe the remaining sensitive adhesive until the sensitive adhesive is wiped clean. However, you should pay attention not to use too much force when you wipe the adhesive. , Otherwise it may affect the finish of the profile product.
