An expandable microwave popcorn package which contains a charge of popcorn kernels suitable for preparation in a microwave oven. The package is formed of front and back panels preferably joined together at the top and bottom ends and at the sides by side panels. The back panel includes two or more sections which are joined along slightly overlapping edges and bonded together by a releasable adhesive, thereby forming lap seam(s). Conversion of the package into a serving vessel is made possible by the releasable nature of the adhesive which allows the lap seam(s) to be disengaged after the popping process is complete. Thus the back panel sections can be detached, and possibly removed, to expose the popcorn within the package. Ideally the heat and steam created by the popping process will diminish the bonding strength of the releasable adhesive thereby enhancing the conversion. Separation lines, along which the structural integrity of the package is relatively weak, may also be used in conjunction with a lap seam to enhance the conversion while avoiding manufacturing problems associated with multiple lap seams.

Microwave popcorn preparation and serving package with releasably

An expandable microwave popcorn package which contains a charge of popcorn kernels for preparation in a microwave oven. The package is formed of front and back panels preferably joined together at the top and bottom ends by an adhesive and at the sides by side panels. The back panel includes a pair of separation lines along which the package material is relatively weak such that a portion of the back panel can be torn from the remainder of the package to expose the popcorn within. Separation lines may be formed by weakening a portion of the bag substrate, by reinforcing the adjacent areas, or by a combination of the two. Side panels are folded to form gussets which allow the package to remain flat during storage, to expand to accommodate the popped kernels. A susceptor is also preferably placed on the front panel opposite the back panel to enhance the popping action.

Microwave popcorn serving package

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.
