Abstract

Packaging material is prepared by coating flat substrates with aqueous dispersions of polymers of vinylidene chloride wherein the aqueous polymer dispersions are mixtures of an aqueous dispersion of 50 to 75 parts by weight of a copolymer A of 85 to 92% by weight of vinylidene chloride and 15 to 8% by weight of an ester of an ethylenically unsaturated carboxylic acid having 3 to 5 carbon atoms with an alcohol containing 1 to 8 carbon atoms and an aqueous dispersion of 25 to 50 parts by weight of a copolymer B of 55 to 67% by weight of butadiene and 33 to 45% by weight of acrylonitrile and/or methacrylonitrile. From 10 to 50% by weight of the ester units of copolymer A may be replaced by units of acrylonitrile, methacrylonitrile and/or vinyl chloride. Up to 20% by weight of the units of butadiene in copolymer B may be replaced by units of one or more esters of ethylenically unsaturated carboxylic acids having 3 to 5 carbon atoms with alcohols containing 1 to 8 carbon atoms. Examples of copolymers are given. The substrate may be fibrous e.g. paper, or films or sheeting of plastics e.g. polyethylene, polypropylene, polystyrene, polyethylene terephthalate, polyvinyl chloride, and metal foils e.g. aluminium foil. The coating may be applied by means of doctor knives, air brushes or rollers, spray, flooding, pouring a dipping means. A further coating containing a copolymer of vinylidene chloride and methyl acrylate may be applied.
