CA 2134320

A polyolefin muiltilayer laminate in which a first layer (A) made of a cycloolefin-based resin, such as an ethylene/cycloolefin random copolymer resulting from copolymerization of ethylene and a cycloolefin represented by the formula (1) given below, or a cycloolefin-based resin blend and a second layer (B) made of an olefin (co)polymer or a composition containing it are laminated. This laminate can be used as a packaging material which is superior in the interlayer adhesion, shapability, moistureproof property, transparency, flexibility, easiness of hand-cutting, heat-sealability and dead-hold property. Image in which n and q are 0 or l, m is 0 or any positive integer, R1 - R18 and R a and R b denote each H, a halogen atom or a hydrocarbon group, wherein R15 - R18 may form, by combining with each other, a monocyclic or polycyclic ring, which may have double bond(s), and wherein R15 - R16 may have terminal-located alkylidene group.
