A film includes a core layer including a homogeneous random alpha-olefin / cyclic olefin copolymer; and first and second outer layers including an olefinic polymer; the film having Young's modulus between about 50,000 and about 200,000 psi, free shrink between about 10% and about 80% at 240° F., and shrink tension of less than about 400 psi, or a shrink force of between about 20 and about 180 grams, at 240° F. First and second intermediate layers including an ethylene copolymer having a melt index less than about 2 g / 10 minutes can be optionally included. Alternatively, a film includes a core layer including an ethylene copolymer having melt index less than about 2 g / 10 minutes; first and second intermediate layers including a homogeneous random alpha-olefin / cyclic olefin copolymer; and first and second outer layers including an olefinic polymer; the film having properties as disclosed above.

A prefilled syringe and syringe assembly having a syringe and a tip cap are produced from materials that do not interfere with the substance contained in the syringe and enable long term storage. The tip cap is made from a blend of a cyclic olefin polymer or copolymer and a thermoplastic elastomer. The thermoplastic elastomer is blended with the cyclic olefin copolymer in an amount so that the normally stiff and hard cyclic olefin copolymer is flexible and resilient to effectively seal and couple to the tip of a prefilled syringe.
