Document Type and Number:
WIPO Patent Application WO/2017/094564
Kind Code:
A1
Abstract:
The present invention provides a multi-layer structure having: a polyamide layer (A) comprising a composition containing an aliphatic polyamide such as a polyamide including C10-12 lactam-derived constituent units and/or C10-12 aminocarboxylic acid-derived constituent units; and a polyamide layer (B) comprising a composition containing, in a predetermined amount ratio, an aliphatic polyamide such as a polyamide including diamine units including at least 70 mol% of xylylenediamine-derived constituent units and dicarboxylic acid units including at least 70 mol% of C4-12 aliphatic dicarboxylic acid-derived constituent units, or a polyamide including a modified polyolefin and C6-12 lactam-derived constituent units and/or C6-12 aminocarboxylic acid-derived constituent units. According to a preferred embodiment of the present invention, this multi-layer structure has excellent flexibility as well as exceptional chemical resistance and gas barrier performance.
