Abstract: 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.

Abstract: The invention relates to a coextruded, multilayered, biaxially oriented and weldable flat film for the production of welded tubular films and to the use thereof for wrapping and packaging foodstuffs. The inventive flat film has two weldable surface layers made of at least one copolyamide and at least one amorphous polyamide and/or at least one homopolyamide and/or at least one modified polyolefin.

Abstract: The invention relates to a biaxial stretch tubular film with five layers and which may be shrunk and sealed, for the packaging and covering of meat, meat with bones or paste-like foodstuffs and use thereof. Said tubular film comprises an inner layer made from a hot-sealing polyolefin and/or modified polyolefin, a core layer made from polyolefin and an outer layer made from at least one polyamide, whereby a further layer made from polyolefin and/or modified polyolefin is arranged between the inner layer and the core layer and between the core layer and the outer layer.

Abstract: The invention relates to a biaxial stretch tubular film with at least five layers and which may be shrunk and sealed, for the packaging and covering of meat, meat with bones or paste-like foodstuffs and use thereof. Said tubular film has the first four layers thereof, counting from the inside out, made from at least one polyolefin and/or modified polyolefin. A layer or several layers follow on said layers which are made from polyvinylidene chloride copolymer and/or polyamide and/or ethylene vinyl alcohol copolymer and/or polyolefin and/or modified polyolefin.

Abstract: The invention relates to laminated, multilayered and weldable flat film for the production of welded tubular films and to the use thereof for wrapping and packaging foodstuffs. The inventive flat film has two weldable surface layers made of at least one copolyamide and at least one amorphous polyamide and/or at least one homopolyamide and/or at least one modified polyolefin, and is produced by laminating at least two single-layered or multilayered and optionally biaxially oriented flat films.

The inventive flat film has two weldable surface layers made of at least one copolyamide and at least one amorphous polyamide and/or at least one homopolyamide and/or at least one modified polyolefin.

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.
