Suitable high temperature processes include cooking food products, such as whole muscle meats, and sterilization of medical instruments. The high temperature bags may be comprised of multilayer films comprising materials that can withstand high temperatures and also have other beneficial properties such as, for example, the ability to be readily heat sealed, durability, no adhesion to food products, and good/improved moisture and gas barrier properties. These high temperature bags can preferably withstand temperatures greater than the boiling point of water, i.e., 212° F., more preferably greater than 300° F. and more even more preferably greater than 350° F. Furthermore, the high temperature bags may be used to freeze and ship products and may be placed directly into a high temperature environment, such as an oven or microwave, in order to cook or sterilize a product contained within the bag.Type: ApplicationFiled: September 18, 2008Publication date: March 26, 2009Applicant: M&Q PACKAGING CORPORATIONInventors: Michael D.

Patent number: 7504158Abstract: A dual ovenable film having a first layer comprising one or more polyamides and a second layer comprising one or more polyamides. The first layer forms the first outer surface of the film. The second layer has a melting point of at least about 210° C. The film is capable of forming a water-containing package by providing two 4 inch by 6 inch sheets of the film each having four perimeter sides, placing the sheets in superimposed, coextensive arrangement having the first layers of the films in contact with each other, and heat sealing three perimeter sides of the sheets together using a ?-inch wide sealing bar at a temperature of 290° F., a dwell time of 0.5 seconds, and a sealing pressure of 40 psig to form an open pouch having heat seals along three of the four perimeter sides. The open pouch can be filled with 100 milliliters of distilled water at a temperature of 73° F.Type: GrantFiled: November 14, 2005Date of Patent: March 17, 2009Assignee: Cryovac, Inc.Inventors: Arthur Leroy Berrier, Cynthia Louise Ebner

Publication number: 20080248268Abstract: The invention relates to a biaxially drawn multilayer tubular film consisting of at least five layers, in which the external and two other layers contain aliphatic (co)-polyamide in a quantity equal to or greater than 50% by weight and are differently assembled. The inventive tubular film is produced by coextrusion and, thereby is seamless. Said tubular film can be used in the form of flood product packagings, in particular as synthetic sausage casing.Type: ApplicationFiled: September 6, 2006Publication date: October 9, 2008Inventors: Ulrich Delius, Bernhard Feron

Publication number: 20080038569Abstract: A composite component such as a seat back for a vehicle comprises a support portion and at least one reinforcing composite layer. The support portion comprises a thermoplastic material and the reinforcing composite layer comprises a polymeric material impregnating a plurality of fibers. The polymeric material of the reinforcing composite layer is integrated with the thermoplastic of the support portion. A method of forming the composite component includes placing the composite layer into a mold, heating the thermoplastic material to a molten state, and disposing the thermoplastic material in the molten state into contact with the composite layer. The method further includes promoting interaction between the thermoplastic material and the polymeric material to integrate the support portion and the reinforcing composite layer. The thermoplastic material supports the reinforcing composite layer and the reinforcing composite layer reinforces the thermoplastic material to prevent failure when subjected to a load.Type: ApplicationFiled: August 10, 2007Publication date: February 14, 2008Inventors: Jonathan A. Evans, Scott C. Schlicker, Marios Lambi
