PLASTICS FILM AND BAGS AND SACKS THEREFROM ABSTRACT A thermoplastics bag whose wall has an outer layer and an inner layer, each of which is formed by melt-extrusion from an ethylene polymer, the outer layer containing an isobutylene polymer in an amount sufficient to increase the coefficient of friction. Also a multi-layer film suitable for use in the manufacture of the bag.
