摘要： A multilayer, heat-shrinkable film contains at least one semi-crystalline polyamide selected from the group consisting of polyamide 6, polyamide 66, polyamide 6/66, and polyamide 6/12. The film may have a total semi-crystalline polyamide content of at least 35 volume percent, based on total film volume, and a total free shrink at 185° F. of at least 35 percent. The film may have an FTIR Transmission Absorbance A1199/A1170 ratio of up to 1.65. The film may be a retortable film, capable of being used in a process for preparing a retorted packaged product. A process for making a heat-shrinkable annular film containing the semi-crystalline polyamide comprises extruding an annular extrudate downward from an annular die, quenching the annular extrudate by applying a quenching liquid to the annular extrudate, reheating the extrudate to an orientation temperature, and orienting the reheated annular extrudate while the reheated annular extrudate is in the solid state, the orientation being carried out with a total orientation factor of at least 2, to produce a film having a total free shrink at 185° F. of at least 10 percent.

摘要： A retortable packaging article is made from a heat-shrinkable film having at least three layers. The first layer serves as an inside layer of the packaging article, and contains a polyolefin having a melting point of at least 241° F., and/or a polyamide copolymer having a melting point of from 275° F. to 428° F. The first layer of the film is heat sealed to itself. The second layer is an inner film layer containing at least one semi-crystalline polyamide that makes up at least 65 weight percent of the second layer. The third layer serves as an outside layer of the packaging article, and comprises at least one member selected from the group consisting of (i) a polyolefin having a melting point of at least 241° F., and (ii) a polyamide copolymer having a melting point of from 275° F. to 428° F. The film exhibits a total free shrink at 185° F. of at least 20 percent. At least one semi-crystalline polyamide makes up at least 35 volume percent of the multilayer film. A process for preparing a retorted packaged product utilizes the retortable packaging article.

摘要： The presently disclosed subject matter is directed to a package comprising a lower film that contains at least first and second compartments separated by a partition. The first compartment can substantially contain a food product and the second compartment can substantially contain a pouch. Specifically, the pouch comprises at least one rupturable seal and houses one or more food additives. An upper film is sealed to the lower film about the perimeter of the package via outer perimeter seal. In addition, the package comprises at least one inner perimeter seal that cooperates with the pouch rupturable seals and functions to isolate the first and second compartments until it is desired to intermix the food additive and the food product.
