MOISTURE-RESISTANT,COATED THERMOPLASTIC FILM HAVING ENHANCED ADHESION TO INKS AND METALLIC LAYERS

摘要

A primer coated thermoplastic film is described comprising an oriented thermoplastic film and a primer coating on at least one side of said film. The primer coating is a moisture resistant coating applied to said film by sequentially coating said film with at least two aqueous solutions, one of which contains a precursor A and the other solution containing precursor B, such that A and B react to form a composition upon said film which is less water-soluble than either A or B.
