  • Patent number: 10487189
    Abstract: A method of making a foam uses the following steps. A mixture is created having a polymerizable condensation polymer and a blowing agent. The polymerizable condensation polymer has hydroxy acid units and unsaturated di-functional units. The unsaturated di-functional units are unsaturated dicarboxylic acid units or unsaturated di-alcohol units. The mixture is expanded to create a froth. The polymerizable condensation polymer in the froth is reacted to create the foam.

  • Publication number: 20190134958
    Abstract: 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.

  • Patent number: 9452592
    Abstract: 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.

  • Patent number: 8911843
    Abstract: One embodiment of the present invention provides a partly-biodegradable system, which comprises a non-biodegradable portion and a biodegradable portion wherein the non-biodegradable portion is easily separated from the biodegradable portion for disposal of the system. In certain embodiments, the system further comprises a cover layer of non-biodegradable film which adheres to the first non-biodegradable portion to form a sealed compartment for food or drink reservation.

  • Publication number: 20140314920
    Abstract: 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.

  • Publication number: 20140186644
    Abstract: Some embodiments of the invention generally relate to a moisture barrier coating that is biodegradable and compostable. Some embodiments also relate to a coating that is dual ovenable. Such coatings may be used to increase moisture resistance and provide non-stick or release characteristics when applied to biodegradable and compostable disposable food packaging and food service items. In some embodiments, a plasticizer or an amide wax are added to a cellulose-ester, shellac, and rosin based coating to increase moisture resistance and reduce brittleness. In other embodiments, phospholipids or medium-chain triglycerides or increased levels of amide wax may be added to the either of the embodiments above to provide enhanced release characteristics.

  • Patent number: 8568808
    Abstract: An intercalated layered silicate comprises a layered silicate and an intercalating agent sorbed between the silicate layers of the layered silicate. The amount of intercalating agent is effective to provide an average interlayer spacing between the silicate layers of at least about 20 ?. The intercalating agent has a formula selected from formulas I through VII described herein. The intercalated layered silicate may be exfoliated by mixing it with a matrix medium and adding sufficient energy to form a dispersed-particle composition. A packaging film, such as a food packaging film, may comprise the dispersed-particle composition.

  • Publication number: 20100255162
    Abstract: The presently disclosed subject matter is directed to a system and method that allows on-demand oxygen generation within a package. Particularly, the disclosed package incorporates a mass of an oxygen generating material within the interior or exterior of the package. The oxygen generating material is contained by some means, for example, in a cartridge, pouch, sachet, or other similar article separate from a packaged product. For applications with fresh red meat, at the time the package is ready for display, oxygen generation is initiated to increase the oxygen concentration within the package interior, thereby allowing blooming of the red meat.
