Abstract
The present invention provides a laminate for automobile parts having a layer A made from a polyamide resin composition containing 70-99 wt % of (a) a specific polyamide polymer, and 1-30 wt % of (b-1) an ethylene copolymer containing an epoxy group and/or (b-2) an ethylene copolymer modified by an acid anhydride, and a layer B made from a resin composition containing (c-1) a polyethylene resin modified by an acid anhydride and/or (c-2) a polyethylene resin containing an epoxy group, wherein the layer A and the layer B are heat-sealed, except when (1) the layer A contains (b-1) alone as the ethylene copolymer and the layer B contains (c-2) alone as the polyethylene resin; and when (2) the layer A contains (b-2) alone as the ethylene copolymer and the layer B contains (c-1) alone as the polyethylene resin. The laminate of the present invention is superior in strength, stiffness and gasoline barrier property that the automobile parts are required to have.
