Film laminate, useful for packaging liquid medical products, especially water-based parenteral fluid or liquid lipophilic emulsion, has 3 or more layers based on polypropylene with no yield after sterilization with superheated steam

摘要

Film laminate, which can be heated in an autoclave and is free from polyvinyl chloride, has = 3 (outside, inside and middle) layers, each containing 60-100 wt.% polypropylene and 40-0 wt.% thermoplastic elastomer, has no measurable yield to DIN EN ISO 517-2 to -3 after sterilization with superheated steam at 121 deg C or over in the hot water spraying process. Film laminate, which can be heated in an autoclave and is free from polyvinyl chloride, especially for packaging liquid medical products, which has = 3 (outside, inside and middle) layers, each containing 60-100 wt.% polypropylene and 40-0 wt.% thermoplastic elastomer, has no measurable yield to DIN EN ISO 517-2 to -3 after sterilization with superheated steam at 121 deg C or over in the hot water spraying process. An Independent claim is also included for the production of the film laminate by co-extrusion or lamination of the layers.
