Abstract
A film for use in packaging foodstuffs has a base of transparent regenerated cellulose film coated on one or both surfaces with a transparent heat-sealable coating produced by applying to the base a solution or emulsion of a thermoplastic substance and drying, and the thus coated base is in turn coated with a thin transparent layer produced by the application to the initially coated base of a solid non-toxic surfactant substance in a liquid followed by evaporation of the liquid. The thermoplastic substance may be nitro-cellulose, a vinylidene chloride-acrylonitrile copolymer, or a vinylidene chloride-vinyl acetate copolymer. The surfactant may be ionic or non-ionic. It may be applied to the initially coated film base dissolved and/or dispersed in an organic solvent miscible with water, in water, or in a mixture of water and one or more organic solvents.
