Abstract

The invention belongs to the technical field of films, and particularly relates to a label film. The PET (polyethylene terephthalate) label film is characterized in that a coating, a PET film, an aluminum layer, an adhesive layer and a substrate are sequentially arranged to form an integrated structure; the coating is formed by mixing matrix resin, an active diluent, deionized water, a defoaming agent, a leveling agent and a wetting dispersant, and comprises the raw materials in parts by weight as follows: 16-70 parts of the matrix resin, 10-55 parts of the active diluent, 9-50 parts of the deionized water, 0.3-0.8 parts of the defoaming agent, 0.4-1 part of the leveling agent and 0.4-1.2 parts of the wetting dispersant; the thickness of the coating is 0.5-1 mu m; the thickness of the PET film is 45-50 mu m; the thickness of the aluminum layer is 401-500 angstroms. The label film has good printing ink adhesion force, and oil fouling produced on the surface of the label film can be prevented.
