Abstract
A glass protective film includes a base film formed by melting a weak adhesive polymer to be adhered to a glass plate by weak adhesion; a first surface of the base film prepared into a weak adhesive surface, which is a mirror surface; and a second surface thereof prepared into a non-adhesive surface which is a rough bead surface. Beads for preparing the rough bead surface are hexagonal, rectangular or triangular beads or ball beads prepared by cutting a film; and the ceiling reach rate of the beads of the rough bead surface is 30% or more.
Claims4
A glass protective film, comprising:
- a base film with an adhesive surface as a first surface thereof and a rough bead surface as a second surface thereof, wherein the rough bead surface of the second surface of the base film comprises polymer film plate microbeads having a thickness, and all having a same regular shape with a size of 200 to 600 μm, selected from any one of the following cut polymer film microbead shapes:
- hexagonal, rectangular, and triangular, and the polymer film plate microbeads being uniformly distributed with a density of between 0.1 g/m2 to 7 g/m2 on the rough bead surface.
