  • Shrink film containing semi-crystalline polyamide and process for making same
    Patent number: 7687123
    Abstract: 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.

  • Heat shrinkable retortable packaging article and process for preparing retorted packaged product
    Publication number: 20080182051
    Abstract: 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.
