Patent number: 11279116Abstract: A zeolite formulation has been identified that is to be included in an arrangement of barrier layers allowing for the entrapment of volatile organoleptic compound (VOCs), in particular, odor causing VOCs, between the barrier layers in order to contain the release of these compounds. The entrapment technique allows for extended time to adsorb, absorb or react such VOCs before they can be absorbed by the product surrounded by the packaging. A zeolite formulation of an odor scavenger layer not having any VOC barrier layers within the film is also disclosed having the capability to contain the release of hydrogen sulfide over a period of at least 20 days.Type: GrantFiled: April 27, 2017Date of Patent: March 22, 2022Assignee: Cryovac, LLCInventors: Larry B.

Patent number: 9452592Abstract: The present invention is directed to a multilayer film having an active oxygen barrier layer that comprises an oxygen scavenging composition that is a blend of a thermoplastic resin (A) having carbon-carbon double bonds substantially in its main chain, a transition metal salt (B), and an oxygen barrier polymer (C) having oxygen barrier properties that can be further enhanced by exposing the composition to a source of ionizing radiation e.g., electron beam radiation. Irradiation improves the oxygen scavenging abilities of the oxygen scavenging composition so that oxygen can be intercepted and scavenged as it passes through the film. The resulting irradiated multilayer film has improved active barrier properties in comparison to the same film prior to irradiation. As result, the multilayer film of the present invention can be used in packaging applications to help maintain a low oxygen atmosphere in the interior of a package.Type: GrantFiled: August 28, 2007Date of Patent: September 27, 2016Assignee: Cryovac, Inc.Inventors: Scott Beckwith, Frank Bryan Edwards, Janet Rivett, Cynthia Louise Ebner, Thomas Kennedy, Rachel McDowell, Drew V.

Publication number: 20140314920Abstract: The present invention provides a multilayer film having an active oxygen barrier multilayer core comprising at least one of 1) an active oxygen barrier layer is sandwiched between two passive oxygen barrier layers, or 2) a passive oxygen barrier layer is sandwiched between two active oxygen barrier layers. In one embodiment, the active barrier layer comprises a composition that is a blend of a thermoplastic resin (A) having carbon-carbon double bonds substantially in its main chain, a transition metal salt (B), and an oxygen barrier polymer (C). In some embodiments the active barrier layer may also include a compatibilizer (D). The passive oxygen barrier layers help to maintain the oxygen barrier properties of the multilayer film after the oxygen absorbing capacity of the active barrier layer has been exhausted. As a result, the useful shelf life of the film can be extended.Type: ApplicationFiled: July 1, 2014Publication date: October 23, 2014Inventors: Scott Beckwith, Frank Bryan Edwards, Janet Rivett, Cynthia Louise Ebner, Thomas Kennedy, Rachel McDowell, Drew V.
