FORMABLE FILM FOR COLD-FORM, BLISTER-TYPE PHARMACEUTICAL PACKAGING

摘要

Cold-formable film composite structures useful for pharmaceutical blister packaging may be constructed from a first polyester surface layer that has a low extractables level, an aluminum layer adhered to the first surface layer, and an additional layer adhered to the aluminum layer. A second surface layer may be adhered to the additional layer. Blister packs may be prepared from such composite structures by cold-forming the structures such that the first polyester surface layer is inside the blister, facing the pharmaceutical. The use of a low-extractables material on the inside surface of the blister minimizes the potential for contamination of the pharmaceutical within the package.
