A container for food includes a paper-based substrate, and at least one grease and moisture resistant coating applied in liquid form to the paper-based substrate. The liquid coating is preferably formed from an aqueous-based dispersion of acrylic-based material. The liquid coating remains resistant to grease and moisture issuing from food at temperatures in the range of about -20.degree. F. to 425.degree. F.

Food trays and the like having press-applied coatings

An expandable collapsed bag, preferably made of paper, suitable for cooking corn in a microwave oven. The bag of the invention has front and back panels and two side panels, each side panel having two or more gussets. These gussets permit relatively free upward movement of the corn and fuller expansion of the bag during cooking. In its collapsed configuration, the back panel is folded to expose a portion of each side panel that forms one gussets. The collapsed bag thereby forms strips extending along each side edge in which the bag is four layers thick. Since a conventionally folded, two gusseted bag has six layers along its edges, the reverse folded bag is thinner and, therefore, advantageous from handling, shipping and storage viewpoints.

Microwavable food package having a bag with reverse folded gussets

A laminate for use in microwave cooking which includes a susceptor formed by depositing a thin layer of microwave-interactive material on a plastic base sheet, and then extrusion bonding that susceptor to a plastic coated paper sheet, without the use of an adhesive.

Microwave package laminate with extrusion bonded susceptor

A perforated susceptor for use in disposable packaging that functions as the cooking container for a microwaveable food product such as popcorn. The susceptor includes a thin layer of microwave-interactive material, such as aluminum with an optical density of about 0.22 to 0.35. This layer is deposited on a substrate of a flexible plastic film. Perforations in the metallic layer are less than 0.060 inches in diameter, do not extend into the substrate, and are arrayed in rows and columns spaced at regular intervals of between 1/16 and 3/16 of an inch, so that the combined surface area of the perforations represents less than 20 percent of the area of the susceptor. The film can be directly bonded, through the perforations, to a sheet that forms part of a package.
