Abstract: This invention provides packages and containers produced by a solid state method for the manufacture of foamed polymeric material. The packages are suitable for pre-cooking or sterilization, insulated transport, cooking vessel, reheating, and storage of food. The gas impregnated thermoforming (GIT) process includes interleaving an article of raw polymeric material with a gas channeling means; exposing the article to a non-reacting gas at elevated pressure to achieve a desired concentration of gas within the polymer, thereby forming a partially gas-saturated article, separating it from the gas channeling means, then decompressing, foaming and forming it at a temperature below the material's melt temperature; and finally trimming it to produce a finished foamed polymeric material and recycleable scrap solid state process foamed polymer.

Abstract: A solid state foaming process permits the use of up to 100 % recycled pre- and post-consumer polymer for the manufacture of foamed polymer material and thermoformed foamed polymer articles. The process enables the optional formation of integral unfoamed skins of controllable depth and crystallinity on foamed polymeric materails suitable for a wide variety of applications. Because this process does not alter the underlying chemistry of the material all scrap from the manufacturing process may be reused without additive to form new foamed polymeric materials and articles.

Abstract: A method for debossing a surface of a thermoplastic material to which an ink is selectively applied. The force generated by the ink as it cures and adheres forms a decorative relief in the thermoplastic material's surface producing an article having aesthetic and tactile appeal without having to use a die to deform the surface and without having to apply and cure the ink in a step separate from the deformation of the surface.

Abstract: A solution is proposed for forming a thermoplastic material (116) into a desired shape. A corresponding method comprises increasing the thermoplastic material's degree of crystallinity by infusing the thermoplastic material (116) with a gas for a period, wherein the thermoplastic material (116) includes a core (304) and a surface layer (306a, 306b) adjacent the core (304), and has a threshold degree of crystallinity above which bubbles will not nucleate when the gas-infused thermoplastic material is heated to its glass-transition-temperature, and wherein the increase in the material's degree of crystallinity includes the surface layer's degree of crystallinity being greater than the core's degree of crystallinity, and less than the thermoplastic material's threshold degree of crystallinity; allowing, for a period, gas infused into the thermoplastic material (116) to migrate out of the material (116); nucleating bubbles in the gas-infused thermoplastic material (116) by causing the gas-infused thermoplastic material (116) to reach a temperature that is at least the glass-transition-temperature of the gas-infused thermoplastic material (116); holding, for a period, the temperature that is at least the glass-transition-temperature of the gas-infused thermoplastic material (116) to allow the bubbles to grow in size; reducing the temperature of the gas-infused thermoplastic material (116) to stop the bubbles from growing in size; and thermoforming the thermoplastic material (116) into a shape.
