Patent number: 5345069Abstract: A gas-flushed microwavable easy-to-open food package is provided which is resistant to impact under temperatures at or below freezing and which is comprised of a flexible lidding film having oxygen-barrier properties hermetically and peelably sealed to a food compartment formed from a polypropylene copolymer material. The lidding film is preferably comprised of oriented polyester, and the food product compartment further comprises a peelable oxygen, barrier film, preferably formed of ethylene vinyl acetate, PVDC and a peelable polyethylene layer. The package is designed to contain a perishable food product, such as a wiener in a bun or other proteinaceous-farinaceous food combinations, and is preferably entirely or partially transparent so as to allow the consumer to readily observe the condition of the food product before purchase.Type: GrantFiled: September 17, 1991Date of Patent: September 6, 1994Assignee: Oscar Mayer Foods CorporationInventor: Paul E.

Patent number: 5167974Abstract: A package is provided for enclosing a proteinaceous product under vacuumized and hermetically sealed conditions. The package has a peelable hermetic reclosure and a body member of semi-rigid preformed plastic with a first planar marginal portion and a central portion shaped to provide a packaging chamber. The package also has a flexible dimensionally stable base member having a corresponding second planar marginal portion and a central portion to provide a closure for said packaging chamber. The two planar marginal portions are adhered together face-to-face by an adhesive to provide at least a portion of the hermetic seal wherein said adhesive is a high molecular weight pressure sensitive hot-melt adhesive having a viscosity of between about 5,000 and about 100,000 centipoise at 300.degree. F. and said adhesive provides a peelable hermetic reclosure.Type: GrantFiled: December 4, 1991Date of Patent: December 1, 1992Assignee: Oscar Mayer Foods CorporationInventors: Paul E.

Patent number: 4866911Abstract: A continuous method of enclosing a proteinaceous product in a vacuumized and hermetically sealed package having a peelable hermetic reclosure and having a body member of semi-rigid preformed plastic with a first planar marginal portion and a central portion shaped to provide a packaging chamber. The package also has a flexible dimensionally stable base member having a corresponding second planar marginal portion and a central portion to provide a closure for said packaging chamber. The method requires placing a sufficient quantity of proteinaceous product in the central portion of the body member to substantially fill the central portion when the package is completed, positioning the first planar marginal portion face-to-face to the corresponding second planar marginal portion, vacuumizing the assembly, and hermetically sealing the package.Type: GrantFiled: November 30, 1987Date of Patent: September 19, 1989Assignee: Oscar Mayer Foods CorporationInventors: Paul E. Grindrod, Ray H. Griesbach, Darrell G. Cornish

Patent number: 4273815Abstract: A laminated film for packaging use which film has at least one lamina of a crystalline flexible polyvinylidene chloride film adhered to a lamina of chlorinated polyethylene film, the chlorinated polyethylene film having a chlorine of concentration of up to approximately 60%, by weight, with the particular chlorine concentration of from 30% to 50%, by weight, being preferred. The laminated film being formed by contacting a polyvinylidene chloride film while in a supercooled noncrystalline state with a chlorinated ethylene film and thereafter effecting crystallization of the polyvinylidene chloride film with substantially random crystal distribution throughout, such as, by heating the thus formed laminate to the crystallization temperature of the polyvinylidene chloride.Type: GrantFiled: March 16, 1972Date of Patent: June 16, 1981Assignee: Oscar Mayer & Co.
