Abstract:
A packaging film or sheet having a styrene-butadiene block copolymer directly melt-bonded to at least one layer of a cyclo-olefin copolymer is disclosed. The films may be made by means of co-extrusion. The packaging film is amenable to thermoforming processes and is particularly suitable for forming blister packaging used in pharmaceutical applications.
