Abstract: Compositions and packaging films are provided having a blend of an amorphous nylon copolymer, a low temperature polyamide, and a high temperature polyamide. The compositions can be used in making heat shrinkable films and food packages having desirable levels of free shrink.

Abstract: Heat shrinkable, oxygen barrier, packaging films, methods of packaging and packages are provided having a myoglobin blooming agent to provide, promote, enhance or maintain a desirable coloration on the surface of a myoglobin-containing meat product.

Abstract: A method of distributing or commercializing fresh meat having the general steps of butchering a slaughtered animal into a plurality of retail cuts; packaging the retail cuts into a plurality of articles wherein each article comprises a polymeric oxygen barrier film having a transparent portion in contact with at least a portion of the fresh meat product; transporting the packaged article to a retail outlet, wherein the packaged article is adapted for retail display and sale without removing the polymeric film and wherein the fresh meat product has a desirable appearance especially a desirable red color e.g. having an “a*” value of at least about 15 for the fresh beef product or of at least about 6 for a fresh pork or fresh poultry product and the color is maintained for at least five days and up to four weeks or more after display.

Abstract: A heat-shrinkable film suitable for forming an easy opening cook-in bag is provided. The film comprises at least five layers, including an inner layer, an inner frangible layer, a barrier layer, an outer frangible layer, and an outer layer. The film is capable of being formed into a bag comprising a lap seal, a top end seal, and a bottom end seal, wherein the seals are heat sealed to a closed condition to contain and protect a product disposed therein. The lap seal, top end seal, and bottom end seal each are able to remain sealed during cook-in conditions. Additionally, the lap seal, top end seal, and bottom end seal each are peelable and easily openable by application of force.

Abstract: A coextruded heat-shrinkable, biaxially-oriented multilayered packaging film comprising a first layer, a second polymer layer, a third polymer layer, and a fourth polymer layer wherein the first polymer layer comprises a first ethylene/?-olefin copolymer preferably, an ethylene/?-olefin copolymer having an ?-olefin comprising 4–8 pendant carbon atoms, a melting point of less than 105° C., a molecular weight distribution Mw/Mn of from 1–2.7, a melt index of from 6.5–34 g/10 min. at 190° C., and is present in the first layer is an amount of from 50–100%, based on the total weight of said first layer. The second layer comprises a second ethylene/?-olefin copolymer having a melt index of from 0.85–6.0 g/10 min.

Abstract: Multilayer thermoformable structures for packaging film applications. The multilayer structures having at least a first layer of polyester, a second layer of a first adhesive and a third layer of a nylon blend formed into a flexible non-oriented film by coextrusion.

Abstract: An easy opening heat-shrinkable bag adapted to be heat sealed to a closed condition to contain and protect a product disposed therein, whereby, at least one heat seal is peelable and readily openable by application of force.

Abstract: An individual end-sealed packaging receptacle, such as a bag, formed from a sheet of heat-shrinkable film having a first edge and an opposing second edge. The packaging receptacle includes a first seal bonding the first edge and second edge to define a tube member having a first bag wall, a second bag wall, first and second opposing lay-flat bag edges, an end and an open mouth. The packaging receptacle includes a second seal through the first and second bag walls, extending laterally across the width of both the first and second walls and thereby closing the end. A method of forming a individual, end-sealed, heat-shrinkable packaging receptacle is also disclosed.
