Abstract
A tubular film for encasing food. The tubular film comprises a material which has been regenerated from a viscose solution. The tubular material is longitudinally stretched by from +8 to +40 percent and transversely stretched by from -20 to +40 percent while wet and the stretch is maintained during drying, said transverse stretch and longitudinal stretch being sufficient to obtain a surface area increase of at least 10 percent from the point of regeneration. In general, the tubular material has a wall thickness of from about 60 to about 90 percent of the same tubular material except without the combined stretch. The invention also includes the method for making the tubular material by stretching the regenerated tubular material while wet and maintaining the stretch during drying.
