| abstract |
The present invention provides a laminated tube excellent in chemical barrier properties, interlayer adhesion and durability, low temperature impact resistance, and elution resistance of low molecular weight components. A layer containing an aliphatic polyamide (polyamide 11, 12, etc.), a layer containing a polyamide 6/66/12 composition, a layer containing an ethylene / vinyl acetate copolymer saponified product, and a layer containing an aliphatic polyketone. And a layer containing at least one set of polyamide 6/66/12 composition and a layer containing saponified ethylene / vinyl acetate copolymer are disposed adjacent to each other.
