BIAXIALLY-ORIENTED POLYESTER MATTE LAMINATING FILM AND MANUFACTURING METHOD THEREFOR

摘要

A biaxially-oriented polyester matte laminating film and a manufacturing method therefor. The method for manufacturing the biaxially-oriented polyester matte laminating film comprises: a matte varnish is coated onto a first surface of a bright biaxially-oriented polyester film so as to form a matte coating layer, the bright biaxially-oriented polyester film and the matte coating layer constitute a substrate (1) of the biaxially-oriented polyester matte laminating film; an aqueous solution of polyethyleneimine is coated onto a second surface of the bright biaxially-oriented polyester film so as to form an intermediate layer (2); and, at least one selected from ethylene-vinyl acetate, low-density polyethylene, ethylene-ethyl acrylate, and ethylene-methyl acrylate is compounded onto the intermediate layer (2) by means of an compounding extrusion process so as to form a hot-melt adhesive layer (3).
