<p>This invention relates to a multi-layer composite comprising one or more sequences comprising a base layer/tie-layer/EVOH/tie-layer/base layer, said composite having on at least one of its outer surfaces a conductive material either impregnated thereon or applied as a film on said outer surface. The base layer is preferably a polyolefin such as polyethylene. These composites are useful as vapour containment layers for fuel tanks.</p> |
