ABSTRACT:
A multi-layer laminated structure comprising a polycarbonate or thermoplastic polyester layer having adjacently adhered thereto a layer comprised of a modified olefin polymer having a stiffness modulus of from 100 to 3,000 Kg/cm.sup.2 and a degree of crystallinity of not more than 33%, in which an unsaturated carboxylic acid or the derivative thereof is grafted to at least a part of a polymer consisting of a hydrocarbon. The laminated structure is excellent in moisture impermeability, oxygen barrier property, adhesion durability under a high temperature and high humidity condition, moldability, processability, and the like, and is useful as a packaging material.
