Abstract: A battery separator of a cellulosic nonwoven substrate coated on at least one surface with a cellulose film and process for making such separator by contacting a nonwoven cellulosic textile substrate with a cellulose or cellulose derivative solution on at least one side of said substrate; converting the solution to a solid cellulose or cellulose derivative having a degree of polymerization of at least 500, preferably at least 600, to form a coated substrate; washing and drying the coated substrate to provide a battery separator having a absorption rate of at least 6 mm/5 min. and a 30% KOH absorption of at least 200 g/m.sup.2.

Abstract: Heat-shrinkable films suitable for packaging food articles such as frozen poultry, primal meat cuts, and processed meat products. In one embodiment, the film may be a biaxially stretched monolayer film of a very low density polyethylene copolymer. In another embodiment, the film may be a biaxially stretched multilayer film comprising a first outer layer of an ethylene-vinyl acetate copolymer, a core layer of a barrier film such as a polyvinylidene chloride copolymer or an ethylene-vinyl alcohol copolymer, and a second outer layer comprising a blend of an ethylene-vinyl acetate copolymer and a very low density polyethylene copolymer. The multilayer film is preferably made by coextrusion of the layers. The films are fabricated into bags useful for the aforementioned purposes. The bags have improved toughness.
