<p>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 the use thereof. Said tubular film comprises an inner layer made from at least one heat-sealable co-polyamide, a middle polyolefin layer and an outer layer made from at least one homo-polyamide and two bonding layers between the inner and middle layers and the middle and outer layers.
