Beschreibung
Zusammenfassung:	Biocompatible laminate structure comprising an alternating stack of layers from polymers A and B or polymer blends AC and BD having the sequence -A-[B-A-] n - or AC-[BD-AC-] n with n from 4 to 36, wherein the layer thickness of layers A or AC and layers B or BD is less than 3 µm, wherein A and B are thermoplastic polymers and C and D are thermoplastic elastomers, at least part of the monomeric building blocks of polymer A, B or A and B are from renewable sources wherein the thermoplastic polymer B has functional barrier properties, wherein the amount of the thermoplastic elastomers C and D in the polymer blends AC and BD is each from 3 to 45 wt.-%, and polymer B and elastomer D are essentially incompatible.
