Plastics film and bags and sacks therefrom

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 th...
