Abstract
The invention relates to a five-layered, biaxially oriented, shrinkable and sealable tubular film for the packaging and wrapping of meat or meat with bones and to the use thereof. The tubular film of the invention has an inner layer comprised of at least one heat-sealable copolyamide, a polyolefin middle layer, and an outer layer comprised of at least one homopolyamide, and two adhesion-promoting layers between the inner layer and middle layer and between the middle layer and outer layer. Such tubular films are remarkable for their superior seal seam strength and high resistance to puncturing.
