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: A pair of parallel elongated flexible panel portions embracingly receive a pair of flat matchbook bundles therebetween with the bundles arranged with the end ends of the bundles spaced apart and the base ends of the bundles extending in opposite directions, the bundle base ends being secured between corresponding ends of the panels. The head ends of the bundles are spaced apart sufficiently to enable the longitudinal midportions of the panels to be appreciably bowed away from each other and opposite marginal edges of the midportions of the panel members have outwardly opening notches formed therein.
