Abstract: The method of forming a microwaveable package, generally from a plurality of liners of material, and incorporating a heat-assist layer preferably intermediately of the liners of material, which said heat assist material comprising powdered carbon, that is originally applied to the inner surface of one of the intended liners, and in register at that location where the layer is desired within the formed microwave package. The material may be imprinted by a gravure or other roller application onto the inner surface of one of said liners of material, or adhesive applied or added onto that adhesive that laminates the liners together, in order to assure that proper and convenient registration of the layer within the laminate material, and provide for its location within the formed package preferably at a lower position where the food or other product is arranged, during microwaving, to attain that necessary heat assist desired from its addition.

Abstract: A microwaveable food container is provided with an accessory which contains a heat assist to facilitate heating of the food. The accessory is secured to the container along two opposite edges of the accessory and is provided with perforations which allow the metallized heat assist to be easily removed. The remaining portion of the container may therefore be recycled.

Abstract: A method of treating yard waste includes introducing yard waste into a chamber wherein the yard waste is impinged by high pressure jet of liquid; the liquid from a group of rotating nozzles. The pressurized liquid stream breaks down the yard waste to create a greater surface area for biological microorganisms to attack, thereby speeding up the decomposition of the waste.

Abstract: A microwavable food product package comprises two separate parts: a bag in which the food is packaged, and an accessory which is placed over a face or wall of the bag. The accessory has a fully metalized surface with a pattern of metal free areas formed in the metallization. The pattern is formed to resemble the break-up or fretting of a continuous unbroken layer of metal when it is heated by microwave energy. The pattern may be formed as a plurality of rows of S's which criss-cross he accessory, or it may be a tight grid pattern of thin lines of unmetalized areas.

Abstract: A microwavable food product package comprises two separate parts: a container in which the food is packaged, and a sleeve which fits around the container. The sleeve includes selected areas upon which microwave interactive material (a metal layer) is printed. The sleeve is fitted over the food package such that the interactive material is in line with the food contained in the package. The metal layer, in line with the food, assists in the heating of the food.

Abstract: A microwave package for packaging a combination of products and ingredients, including a package formed as a bag and constructed of paper, polymer film, or the like, having collapsible gussets formed at each side, a first product chamber formed internally at a lower location of the package, at least a pair of heat seals formed upwardly of the bag, and one or more upper chambers formed therein for holding of seasoning and flavoring ingredients within said upper chambers, while a food product, or the like, to be cooked as arranged within the lower formed chamber, so that during microwaving, said seals are strategically broken due to generated heat and pressure to provide for a deposition of the flavoring onto the cooked or cooking food product to provide a readily servable food fully seasoned upon conclusion of its microwave cooking.

Abstract: An improved microwavable package of laminar construction, having its inner layer constructed of a film whose inherent seal strength is sufficiently high that the inside of the package need not have extraneous reinforcement to maintain its integrity filling, storage, distribution and cooking. The microwavable package is ventable and easily opened by virture of a strip of heat sealable adhesive coated along its top edge immediately inside the opening of the bag and having a seal strength less than that of the package formed seals, to mask the package's normal seal strength.

Abstract: A multi-layered packaging material and method of making same, for use in wrapping, packaging and shipping articles, is disclosed. The multi-layered packaging material includes a flexible layer of food grade paper material having a predetermined width, a strip layer of microwave coupling material which becomes hot in a microwave oven when exposed to microwave energy and having a substantially smaller width than the flexible layer, and a masking layer of food grade paper material having a dimensional size only slightly larger than the strip layer. The layers are adhesively bonded and laminated together with the overlapping edges of the strip layer being adhesively bonded to the flexible layer.

Abstract: A microwavable package incorporating controlled venting, including a bag formed of a series of walls, the front, back, side gusseted, and bottom walls, with the walls being of the type formed of a series of laminates constructed of at least a pair of laminar materials, forming at least an inner and outer layer for the structured bag, a vent chamber provided between select of said laminates to afford a controlled venting of the cooking generated pressure and steam from the interior of the bag to its exterior during a cooking process, at least one vent passage provided through the inner laminar material within the region of the disposed vent chamber, said vent chamber extending to the exterior of the bag, whereby during the heating of an item within the bag its generated pressure and steam enters into the vent chamber by way of the vent passage and is released exteriorly of the bag during cooking, while maintaining the integrity of the package and its upper seal during the process.

Abstract: A microwavable package, comprising a folded package for use in holding a variety of cookable items, such as popcorn, other food products, or other substances, all to be heated within a microwave oven, the package being formed of a polymer material, comprising one or more liners of such laminated material, with the package being formed into the tubular configuration, and having a paper or paper-like web of material located and adhesively secured within its manufacturer's joint; the formed tubular like material is then folded at its bottom segments, adhered temporarily through the usage of a hot melt of other adhesive, and having a paper or paper like seal applied thereover, to form a fully integrated and foldable package which is capable of functioning and maintaining its structural integrity even when exposed to the energy of a microwave oven.

Abstract: A microwave package for packaging a combination of products and ingredients, including a package formed as a bag and constructed of paper, polymer film, or the like, having collapsable gussets formed at each side, a first product chamber formed internally at a lower location of the package, at least a pair of heat seals formed upwardly of the bag, and one or more upper chambers formed therein for holding of seasoning and flavoring ingredients within said upper chambers, while a food product, or the like, to be cooked as arranged within the lower formed chamber, so that during microwaving, said seals are strategically broken due to generated heat and pressure to provide for a deposition of the flavoring onto the cooked or cooking food product to provide a readily servable food fully seasoned upon conclusion of its microwave cooking.
