Zusammenfassung:A tube for a medical container has a tube wall which consists of at least two layers. According to the invention, at least one layer contains a styrene-containing thermoplastic polymer (S-TPE), in particular a styrene-butadiene block copolymer (SBC) or a copolyester, a copolyester ether or a cyclic olefin copolyester. The at least one other layer contains ethylene-vinyl acetate copolymer (EVA), preferably with a vinyl acetate (VA) portion in the ethylene-vinyl acetate copolymer of from 10% to 30%, preferably 14% to 28%. The EVA can be mixed with a thermoplastic polybutene and/or SEBS to improve the tube properties. The tube wall can have a two-layer structure with an inner or an outer layer which contains the S-TPE, copolyester, copolyester ether or cyclic olefin copolyester, or a three-layer structure with an outer and inner layer containing the S-TPE or copolyester or copolyester ether.
