STERILISIERBARE, MEHRSCHICHTIGE KUNSTSTOFFMATERIALIEN FUER MEDIZINISCHE GEFAESSE.

摘要

Flexible container has a body section of plastics film having at least two layers, with one, inner, layer formed of a selected, crosslinkable material free of leachable plasticiser and a second outer layer formed of material which is substantially non crosslinkable and has a higher meltinq point than the first layer. The body section is irradiated to achieve a selected level of crosslinking and heat resistance in the first layer. The container is sterilised before use. Pref. inner layer is of poly(ethylene vinyl acetate) containing 10 to 35 wt.% vinylacetate units and the outler layer is of polyethylene, polypropylene or copolymers, blends, or alloys.
