Extruded Sheet

Extruded Sheet ProcessThe extrusion of copolyester sheet process involves the extrusion of molten polymers through a flat die to form a thick film. This film is "pinned" to the surface of a chill roll with another roll to ensure proper clarity and gauge control. A series of 2 to 3 rolls are use to quench the molten polymer immediately creating a very clear sheet with thicknesses greater than 10 mils.
