Abstract
A laminate suitable for use as wrapping or packaging materials for foods and industrial materials is disclosed, which is produced by laminating a thermoplastic resin composition which comprises (1) 10 to 95 % by weight of an ethylene copolymer composed mainly of units derived from ethylene and units derived from an unsaturated carboxylic acid anhydride and (2) 70 to 5 % by weight of a flexible resin having an MFR (190.degree. C.) of 0.1 to 1,000 g/10 min, to one or more kinds of substrates selected from thermoplastic resins, metals, papers, and fabrics. A process for efficiently producing the laminate is also disclosed.
