Patent number: 6231905Abstract: A packaging system and method utilizes a modified atmosphere package including a first package and a second package. The first package includes a non-barrier portion substantially permeable to oxygen, while the second package is substantially impermeable to oxygen. After a food product such as raw meat is placed within the first package, the first package is sealed and then inserted into the second package without sealing the second package so as to create a pocket between the first and second packages. The system and method first employ an oxygen reduction technique such as evacuation, gas flushing, and/or scavenging to quickly reduce the oxygen level in the pocket to a first non-zero level, and then employ an activated oxygen scavenger to further reduce the oxygen level to zero percent after the package is sealed. The oxygen scavenger is activated with an oxygen uptake accelerator to increase the rate at which the oxygen is absorbed.Type: GrantFiled: October 8, 1998Date of Patent: May 15, 2001Inventors: Gary R. DelDuca, Alan E. Deyo, Vinod K. Luthra, Wen P. Wu

Patent number: 6183790Abstract: A modified atmosphere packaging method creates a modified atmosphere in a package including an inner package and an outer package. The inner package is composed at least partially of a polymeric material substantially permeable to oxygen, while the outer package is composed of a polymeric material substantially impermeable to oxygen. After a food product such as raw meat is placed within the inner package, the inner package is flushed with a desired mixture of gases to substantially remove oxygen from the inner package. The flushed inner package is then sealed and inserted into the outer package without sealing the outer package. Next, the outer package is flushed with the desired mixture of gases to substantially remove oxygen from the outer package. After flushing the outer package, the outer package is sealed. An oxygen scavenger is provided in the package to substantially absorb any residual oxygen within the package.Type: GrantFiled: August 27, 1999Date of Patent: February 6, 2001Assignee: Pactiv CorporationInventors: Gary R. DelDuca, Alan E. Deyo, Vinod K. Luthra, Wen P. Wu

Patent number: 6132781Abstract: A modified atmosphere package includes first and second compartments separated by a partition member that is substantially permeable to oxygen. The first compartment contains an oxygen scavenger activated with an oxygen scavenger accelerator. The second compartment contains a retail cut of raw meat. Various techniques are employed to rapidly reduce the oxygen level in the second compartment below pigment sensitive levels so that the growth of metmyoglobin is inhibited. Some of these techniques increase the flow of oxygen from the second compartment to the first compartment through the partition member, while other techniques directly absorb oxygen within the second compartment by locating a second oxygen scavenger within the second compartment.Type: GrantFiled: December 17, 1999Date of Patent: October 17, 2000Assignee: Pactiv CorporationInventors: Daniel G. Carr, Glenn C. Castner, Gary R. DelDuca, Rollie H. DeMay, Alan E. Deyo, Stephen L. Goulette, Darryl P. Hansen, Vinod K. Luthra, Allen J. Norby, Robert A. Sloan, Jill F. Thompson
