摘要：
Multilayer laminates formed from at least two layers. The first layer being a flexible blow moldable thermoplastic polyamide composition and the second layer being a vinyl alcohol composition. These laminates can withstand high temperatures for extended periods of time, possess low temperature impact strength, and have resistance to permeation of fuel compositions. These laminates are especially suited for fuel tanks for motor vehicles.
