Abstract: Heat-sealable packaging film producing a peelable seal, process for the preparation thereof and packages made therefrom or comprising such a film. This film produces such a seal on a wide range of packaging films, including polyester, polyvinyl chloride, polyamide and polyacrylonitrile films owing to:1. its chemical composition which comprises:(a) 55 to 95% by weight of at least one ethylene polymer selected from polyethylene having a density of from 0.91 to 0.93 g/cm.sup.3 and an ethylene-vinyl acetate copolymer containing at most 10% by weight of vinyl acetate,(b) 5 to 30% by weight of polystyrene, and(c) 0 to 20% by weight of a thermoplastic, elastomeric styrene-butadiene-styrene or styrene-isoprene-styrene block copolymer, and2. the fact that that face of the film which is intended to form the peelable seal, has a surface tension of from 35 to 50, preferably of 37 to 45 millinewtons per meter. The film is prepared by extrusion followed by a corona discharge pretreatment of said face.

Abstract: A heat sealable packaging film particularly suitable for producing a peelable seal by heat sealing on polystyrene.For this purpose, the composition of the film comprises:(a) 50 to 70% by weight of at least one ethylene polymer having a melt index of 0.5 to 7 g/10 min and selected from polyethylene having a density of from 0.910 to 0.925 g/cm.sup.3 and an ethylene-vinyl acetate copolymer containing at most 7% by weight of vinyl acetate.(b) 20 to 30% by weight of at least one ethylene-vinyl acetate copolymer containing 20 to 30% by weight of vinyl acetate and having a melt index of 0.5 to 7 g/10 min, and(c) 10 to 20% by weight of a styrene homopolymer having a melt index of 0.5 to 7 g/10 min.Also provided are packages including a container made from polystyrene and a covering film for the said container, which is made from the aforesaid film, laminated or not on other films.

Abstract: A modified regenerated cellulose film comprising regenerated cellulose and certain modified starches is clear and transparent and has substantially the same mechanical and optical properties as conventional unmodified regenerated cellulose films. The modified starches used are starches degraded by oxidation and/or hydrolysis, uncrosslinked ethers or esters of starch or of starches degraded by oxidation and/or hydrolysis or mixtures thereof. The amount of modified starch used represents 1 to 49% by weight, preferably 5 to 30% by weight, based on the total weight of cellulose and modified starch. Methods for the production of said modified regenerated cellulose film either by the viscose process or by the cuprammonium process are also described.
