<p>The invention relates to a five-layered, biaxially-oriented, shrinkable, sealable tubular film for the packaging and wrapping of paste-like foodstuffs, meat and meat with bones and use thereof. Said tubular film comprises an inner layer made from at least one co-polyamide and at least one amorphous polyamide and/or at least one homo-polyamide and/or at least one modified polyolefin, a layer of a modified polyolefin, a middle layer made from at least one homo-polyamide and/or at lest one co-polyamide and/or at least one co-polymer of ethylene with vinyl alcohol and/or a modified polyolefin, a layer of at least one ethylene/vinyl alcohol co-polymer and an outer layer made from at least one polyolefin and/or at least one modified polyolefin. Such tubular films have a significant improvement in the resistance of the sealed join, in particular at low sealing temperatures, a high impermeability to oxygen and a comparable to clearly greater resistance to puncturing, relative to conventional films.</p> |
