With this process, a sheet of plastic is heated and then either draped (thermoforming) or drawn by vacuum (vacuum forming) over a male or female profile to produce a three-dimensional shape. Large surface areas can be produced, and tools are relatively inexpensive to manufacture.
Example products include shower trays, disposable confectionery trays, clamshells, plant trays, disposable cups and decorative wall panels.
