OVERVIEW:
Sheet Extrusion

Sheet is distinguished from film by its thickness: anything over 0.25-mm is considered sheet. The process closely resembles cast film extrusion. Thinner sheet is typical thermoformed into trays, clam shells, cups or bowls, whereas thick sheet may be used for signage, refrigerator liners and truck bed liners. Common sheet extrusion materials include PET, high-density polyethylene, polystyrene and ABS. Sheet can be produced in either single or multi-layer formats.
