    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.

    Abstract: A container for holding and heating food includes a plurality of cavities each disposed in a body of a wall, each having an opening through an interior surface of the wall, and each operable to hold moisture and to release the moisture through the opening when the body of the wall is warm. The body of the wall is disposed between the interior surface of the wall, which contacts the food when the container holds the food and the food is being heated, and the exterior surface of the wall, which is exposed to the environment surrounding the container.

    Abstract: A method for infusing gas into a thermoplastic material includes positioning a sheet of a thermoplastic material into a vertical or substantially vertical position; positioning a sheet of a gas-permeable material into a vertical or substantially vertical position; and winding together the positioned sheet of thermoplastic material sheet and the positioned sheet of gas-permeable material to form a roll of the thermoplastic material interleaved with the gas-permeable material, the interleaved roll having a longitudinal axis oriented in a vertical or substantially vertical position. The method also includes exposing the interleaved roll to an atmosphere of a gas pressurized to infuse the thermoplastic material with the gas, while the longitudinal axis of the interleaved roll is oriented in a vertical or substantially vertical position; and then unwinding the gas-infused interleaved roll, while the longitudinal axis of the interleaved roll remains in a vertical or substantially vertical position.
