The invention relates to a five-layered, biaxially oriented, shrinkable, sealable tubular film for the packaging and wrapping of paste-like foodstuffs, 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 copolyamide and at least one modified polyolefin, a layer of a modified polyolefin, a middle layer comprised of at least one homopolyamide and/or at lest one copolyamide and/or at least one copolymer of ethylene and vinyl alcohol and/or a modified polyolefin, a layer of at least one ethylene-vinyl alcohol copolymer, and an outer layer comprised of at least one polyolefin and/or at least one modified polyolefin. Such tubular films involve a significant improvement in the seal seam strength, in particular at low sealing temperatures, a high impermeability to oxygen and a comparable to markedly higher resistance to puncturing compared to prior art films.
