Abstract: A microwave susceptible insulated packaging material includes a thermal insulating layer, which may be a fiberfill batt. The insulating layer is laminated to at least one layer of a co-extruded film which has been coated on one surface with a microwave susceptible material, such as aluminum or aluminum coated with a food-safe contacting polymer sealant. The packaging material can be used to form a container, such as a pouch, or as a label or as a lining for a container. The packaging material may be coated also with a printable coating material.

Abstract: The present invention relates generally to packaging materials which enhance food freshness, particularly for foods having a high fat content. The packaging materials of the present invention comprise an aldehyde scavenger, such as, polyethylene imine, and optionally, an oxygen scavenger.

Abstract: The present invention relates generally to compositions of polyalkylene imine ("PAI"), particularly polyethylene imine ("PEI") and polyester polymer(s) (including copolymers and derivatives thereof); such compositions can be used in producing films or devices which are capable of scavenging unwanted aldehydes. More specifically, the preferred compositions of the present invention comprise a PAI substantially discontinuous phase and a polyester or copolyester substantially continuous phase in a weight ratio of PAI to polyester polymer of about 0.001-30:100 which optionally also includes a binding agent.

Abstract: The present invention relates generally to recycled plastics which exhibit noxious odors. More specifically, the present invention is directed to a method of reducing unwanted odors in such recycled plastics by incorporating a polyalkylene imine ("PAI"), more preferably polyethylene imine ("PEI").

Abstract: The present invention relates generally to compositions of polyalkylene imine ("PAI"), particularly polyethylene imine ("PEI") and polyolefin polymer (including copolymers and derivatives thereof); such compositions can be used in producing packaging films for oil containing foods, whereby the film is capable of scavenging unwanted aldehydes from the food product. The preferred compositions comprise a PAI substantially discontinuous phase and a olefinic polymer (including copolymers or derivatives thereof) substantially continuous phase in a weight ratio of PAI to olefinic polymer of about 0.001-30:100 which optionally also includes a binding agent.

Abstract: Method of making tablets for active ingredient delivery by compressing a mixture of active ingredient and granular, high viscosity, fully hydrolyzed polyvinyl alcohol or copolymer of vinyl alcohol with methyl acrylate or methyl methacrylate. By use of a crystalline, heat treated polymer, a tablet providing quick active ingredient release is obtained. By using an amorphous, non-heat treated polymer a tablet providing prolonged active ingredient release is obtained. By using blends of crystalline and amorphous polymers, tablets having a range of active ingredient release characteristics can be obtained. The granular, high viscosity, fully hydrolyzed polymers provide flowability, compressibility and processing versatility advantages over conventional tablet binders.

Abstract: A method comprising forming a water-in-oil emulsion of an aqueous phase comprising discrete water-insoluble particles an an aqueous solution of a water-soluble polymerizable monomer, polymerizing said monomer, phase-inverting the water-in-oil emulsion to an oil-in-water emulsion, removing the oil phase from the phase-inverted emulsion to form an aqueous latex, adding to the latex an ethylenically unsaturated polymerizable second monomer, and polymerizing said second monomer to produce hydrophobic resin-encapsulated water-insoluble particles; and the resulting encapsulated particles.
