Estimating the term…
The invention relates to a multilayered, biaxially oriented, shrinkable and sealable tubular film for the packaging and wrapping of meat, meat with bones, and paste-like foodstuffs and to the use thereof. The inventive, preferably five-layered, tubular film has an inner layer comprised of at least one copolyamide and at least one amorphous polyamide and/or at least one homopolyamide and/or at least one modified polyolefin, a middle polyolefin layer, and an outer layer comprised of at least one homopolyamide and/or at least one copolyamide and/or at least one copolymer of ethylene-vinyl alcohol and/or a modified polyolefin. Two adhesion-promoting layers are situated between the inner layer and middle layer and between the middle layer and outer layer. The film according to the invention has significantly increased seal seam strength even at low sealing temperatures and high resistance to puncturing.
A multilayered, preferably five-layered, biaxially oriented, shrinkable, sealable tubular film for the packaging and wrapping of meat, meat with bones, or paste-like foodstuffs, characterized in that the tubular film is constituted of an inner layer comprised of at least one copolyamide and at least one amorphous polyamide and/or at least one homopolyamide and/or at least one modified polyolefin, a middle polyolefin layer, and an outer layer comprised of at least one homopolyamide and/or at least one copolyamide and/or at least one copolymer of ethylene-vinyl alcohol and/or a modified polyolefin, and two adhesion-promoting layers which preferably consist of the same material and are situated between the inner layer and middle layer and between the middle layer and outer layer.
