Two films firms are offering blister film alternatives to the standard polyvinylidene dichloride-coated PVC used in pharmaceutical packaging.
Tekni-Films said it introduced Novinex, coextruded barrier films containing cyclic olefin-based resins, touting them as vinyl-, halogen- and plasticizer-free.
Competitor Rexam Pharmaceutical Packaging said it is developing film based on cyclic olefin copolymers with protective outer layers of polypropylene.
Tekni-Films of Somerville, N.J., said Novinex provides moisture barrier equal to PVDC while providing safety and environmental advantages. They are coextruded films and are less likely than laminates to become contaminated while cavities are made during thermoforming, according to Tekni-Films. It said Novinex processes easily and doesn´t crack during thermoforming.
Rexam´s Integra Pharm C has stiffness and thermoforming properties as good or better than PVDC-coated PVC, claimed the Mundelein, Ill., company. It too is coextruded and contains no chlorine or fluorine in its materials. Its barrier matches PVDC-coated PVC but it is less dense than conventional constructions.
