Protective film has now become a common material in daily life. From cars to mobile phones, there is a thin film attached to it. It protects the surface of objects and prevents objects from being transported and stored. The surface is scratched and corroded during the process, which guarantees the original smoothness of the object to a certain extent. The protective film is divided into PP material, PVC material, AR material, OPP material and PE material according to the material. Protective film is more common in daily life, such as newspapers, magazines and other printed materials that we come into contact with every day, furniture such as dining tables and desks, kitchen supplies such as stainless steel cabinets, decoration materials such as marble and flooring, and some fresh food Wait for the surface of the item.


PP material appeared on the market in the early days. Because it has no adsorption capacity and requires glue to stick it, it is easy to leave traces of glue and is gradually eliminated by the market. PVC material, its characteristic is that the material feels soft, but the material is relatively thick, the light transmission is poor, and the color will turn yellow after using it for a long time. AR material is a synthetic material with strong resistance to friction and scratching, and it does not need to be glued. PE material, soft material with certain elasticity and stretchability, good light transmittance, and more beautiful. Depending on the material, the purpose is different. For example, PE material is mainly used for aluminum plates, films, glass plates in the printing industry, hardware industry, wire and cable industry, and some semi-finished products that need to be rolled and packaged. AR material is mainly used for screen protection.





However, some protective films will have problems such as residual glue and degumming during use. There may be several reasons for their occurrence: the surface of the film is not cleaned. We require that the surface of the object before the film is free of chemical residues such as grease. If these chemical residues are not cleaned up, they will easily react with the glue and cause degumming. In addition, the improper ratio of glue used or the quality is not good enough to easily cause the problem of residual glue and degumming of the protective film.


The degumming and residual glue of the protective film have always been a problem that plagues everyone, so how can we solve it? The residual glue of the protective film has a great relationship with the peeling force of the protective film. Generally speaking, the adhesion is proportional to the peeling strength of the protective film. The stronger the viscosity, the worse the peeling strength; in addition, the quality of the adhesive The worse, the worse the peel strength. We usually increase the adhesion additives when applying the film, or replace the glue to reduce the appearance of residual glue. The degumming is mostly because the pressure glue used in the protective film product is too sticky, which is easy to cause degumming when the product is peeled off. Our users can wipe with alcohol and wipe off the pressure glue.
