摘要： A co-thermoforming process for forming thermoplastic foam sheet of low density and small cell size. The sheet is formed from multiple webs of thinner gauge polystyrene foam which permits improved control of cell size and resultant functionality of product thermoformed from the sheet. Adhesion of the webs is achieved in the thermoforming process. The co-thermoformed products have improved ductility and surface characteristics.
