Abstract

A coated film comprises an oriented film of stereoregular polypropylene having an adherent coating comprising a copolymer of ethylene and an unsaturated ester of a carboxylic acid having only one unsaturated group and being copolymerizable with ethylene in the presence of initiates capable of generating free radicals. Suitable esters are those of the formula RCOOR1 wherein R is a saturated or cyclic hydrocarbon group optionally bearing halogen and/or alkoxy substituents or a hydrogen atom or an alkoxy group and R1 is an alkenyl radical having a terminal >C=CH2 grouping, and those of the formula R2COOR3 wherein R2 is an alkenyl radical such that R2COOH is an acrylic or substituted acrylic acid and R3 is a saturated or cyclic hydrocarbon group optionally bearing halogen and/or alkoxy substituents. Prior to coating the polypropylene film may be subjected to pre-treatment to cause surface oxidation by any of the known methods (subjection to corona discharge being preferred). The coating may also comprise pigments, dyes, plasticizers, tachifiers, slip agents, anti-blocking agents and anti-static agents and may be applied as a solution or dispersion, e.g. by spraying, brushing, rolling or dipping, or as a hot melt or as a cast film. The coated films may be laminated to other films of the same or different material using the coating as adhesive (see Division B5). Specification 715,914 is referred to.
