Ynnovation  protective film is made from a new type of self-adhesive polymer material and is produced using a co-extrusion blown molding process. The company is the first in the Chinese market to develop PE self-adhesive co-extruded protective films for products such as electronics, color-coated sheets, and stainless steel. Unlike traditional adhesive-coated protective films, the self-adhesive protective film can be applied to the surface of products without the need for adhesive, thus avoiding the residual glue defects associated with traditional adhesive application processes. Additionally, the self-adhesive co-extruded protective film involves no solvents during production or use, resulting in no volatilization, no odor, stable tackiness, and easy removal. It is an environmentally friendly green film.
