Abstract: A protective film includes a non-adhesion layer and adhesion layer, and the non-adhesion layer further includes a surface layer and middle layer, where the surface layer of the non-adhesion layer is formed from a blend of Homo-polypropylene(H-PP) and low density polyethylene(LDPE), the middle layer of the non-adhesion layer is formed from a blend of high density Polyethylene(HDPE) and LDPE among Polyethylene series, and the adhesion layer is formed from thermoplastic elastomer added with low hardness plastic material, allowing the protective film of the present invention not to yield melting and thus sticking issues easily, and ensuring that the protective film has a good attachment and unwinding nature on application.
