Verpackung für zu sterilisierende Artikel

摘要

Packaging for articles to be sterilized consists of an, optionally deep-drawn, plastic sheeting that forms a cover and a length of paper that forms the package backing, the paper being peelably sealed with the sheeting, where the plastic sheeting (4) is a multilayer sheeting whose side facing the paper (6) is a copolymer consisting of at least one a) ethylene polymer and one ethylene vinyl acetate copolymer as well as b) a styrene homopolymer and/or c) a rubber-like polymer. Constituent a) amounts to 55-95 wt. % as a polyethylene polymer with a density of 0.91 to 0.93 g/ccm and a melt index of 0.5 to 7.0 g/10 min. and the ethylene vinyl acetate copolymer has at most 10 wt. % acetate. The styrene homopolymer b) amounts to 0 to 30 wt. %. Constituent c) is present as an elastomeric thermoplastic styrene-butadiene-styrene block copolymer or a styrene-isoprene-styrene block copolymer amounting to 0 to 20 wt. % and/or a polybutytlene or polyisobutylene polymer amounting to 0 to 30 wt. %. The paper for the package backing is a paper treated with plastics, with a mean gas permeability of at least 0.50 mu m/Pa.s. The plastic sheeting is sealed with the paper web.
