CO-EXTRUDED MASK LAYER

摘要

Co-extruded multilayer sheets that include a mask layer (12) and a polymer layer (14) are described. The mask layer (12) exhibits a low level of adhesion with the polymer layer (14) so it can be removed. The mask layer (12) can adhere to the polymer layer (14) during thermoforming and other secondary processing steps. The multilayer sheets can include any number of additional layers.
