Abstract

The invention provides a single-faced tape with a protective film. The single-faced tape comprises a base film layer, a printing layer, an adhesive layer and a protective film, wherein the base film layer is of a sheet film structure; the printing layer refers to printing ink coating the base film layer; the adhesive layer is adhered onto the printing layer, and comprises a two-layer structure: the first layer is a tackifying adhesive film adhered onto the surface of the printing layer, the tackifying adhesive film is an EVA resin adhesive film in which stearic acid-modified magnesium hydroxide is contained, the second layer is a tackifying resin containing magnesium hydroxide ground grains, and the surface of the first layer is coated with the tackifying resin; the protective film is of a film structure, is adhered onto the surface of the adhesive layer and comprises a first film layer attached onto the surface of the adhesive layer and a second film layer attached to the surface of the first film layer; the first film layer is the EVA resin adhesive film containing stearic acid-modified magnesium hydroxide; the second film layer is a release film. The single-faced tape with the protective film, prepared by a corresponding preparation method, is high in cohesiveness, and the tensile strength and breaking strength can be effectively improved.
