UNIDIRECTIONALLY-ORIENTED FILMS COMPRISING THERMOPLASTIC POLYESTERS

摘要

The invention relates to an unidirectionally-oriented film comprising a thermoplastic polyester and a polycarbonate. The unidirectionally-oriented film may further comprise an anti-blocking agent and/or a slip agent. Depending on its width, the films of the invention may be used for food packaging; it may be used for strapping cartons, boxes, pallets, textile bales; and it may be used for woven tape fabric. The fabric woven from films of the invention may be used for making sacks, flexible intermediate bulk containers, hot fill jumbo bags for materials such as bitumen, PVC coated fabrics for flex signage, carpet backing, geo textiles, geogrids, metallised fabrics, and self-reinforced composites.
