  • Patent number: 8993944
    Abstract: Packaging and a dessert food product combines a hot portion and a cold portion. In one embodiment, the dessert combines hot pie with a topping of ice cream in a single package. In one aspect of the invention, the microwaveable food product and package incorporates a food package that simultaneously includes various susceptor films that allow for differential heating of food. The susceptor film(s) shield the cold-portion food products from being heated in the microwave while they provide even heating of the hot portion of the product. The packaging provides a quick, convenient and tasty dessert with minimal effort. In another aspect of the present invention, the pie and ice cream formulation has been optimized to maintain superior flavor and texture properties after freezing and microwave reheating.

  • Patent number: 8658952
    Abstract: A microwave heating construct comprises a first panel and a second panel, each comprising a microwave energy interactive material. The panels are partially joined to one another in an opposed, facing relationship such that an unjoined area is defined between the first panel and the second panel. The unjoined area is in communication with an open peripheral edge of the construct. The first panel includes an aperture in communication with the unjoined area between the first panel and the second panel.

  • Patent number: 8642145
    Abstract: A method reclaims metalized polymer film or mixtures containing metal and/or metal alloys into a metal-containing, polymeric film. The resulting film structure has better oxygen and moisture barrier properties when metalized than plain metalized polymer films. The polymer to be reclaimed, originates in sheet form, and is densified, as by shredding, pelletizing and/or re-extruding into fine particulate form such as chips or pellets. The reclaimed polymeric film can be used, in a range of concentrations, to produce biaxially oriented polyester film for metalizing.

  • Publication number: 20140021198
    Abstract: A microwave packaging material including a plurality of susceptors is disclosed. Each susceptor includes a plastic film or polymer with a metal layer on one surface of the plastic film and a paper adhered to the plastic film opposite the metal layer. A patterned adhesive is bonded between a first susceptor layer and a second susceptor layer in a pattern bond creating sealed air pockets. A paper board substrate is adhered using an adhesive in a bond pattern to one of the susceptor layers facing the metal of the respective susceptor layer to provide the microwave packing material rigidity. Upon exposure to microwave energy in a microwave oven, moisture is trapped between the paper board substrate and the susceptor layer creating a vapor pressure that causes the sealed air pockets to form expanded air pockets.

  • Patent number: 8629380
    Abstract: A thermally insulated susceptor structure includes a dimensionally stable corrugated base, a first susceptor, and a second susceptor. At least one of the first susceptor and second susceptor may circumscribe one or more microwave energy transparent areas that allow the transmission of microwave energy through the respective susceptor and/or create localized fields that enhance heating, browning and/or crisping of an adjacent food item.

  • Patent number: 8610039
    Abstract: A vent assembly includes a bag construction configured to contain a food product such as a popcorn charge. The bag construction is formed of at least one sheet of polyester film material and configured to expand from a collapsed configuration to an expanded configuration when the food product is heated in a microwave oven. The vent assembly includes a first portion of the bag construction and a second portion of the bag construction that is configured to be folded against the first portion. The second portion includes a venting structure formed in the sheet of polyester material. An adhesive is applied to at least one of the first portion or the second portion. The adhesive is configured to adhere the first portion to the second portion so that the vent is at least partially sealed while the bag construction is in the collapsed configuration and to release the first portion from the second portion as the bag construction expands to the expanded configuration to allow the vent to at least partially open.
