Abstract

The present invention provides a multi-layer laminate comprising:
(A) a layer formed from an ethylene/cycloolefin random copolymer which is a copolymer of ethylene and a cycloolefin represented by a specific formula (e. g., tetracyclododecene), or a layer formed from a cycloolefin resin which is a graft modified product of the ethylene/cycloolefin random copolymer, or a layer formed from a cycloolefin resin composition comprising the cycloolefin resin and a polyolefin, and (B) a polymer layer having an oxygen permeability, as measured at 23 °C and RH of 0 %, of not more than 10 cc(STP)×mm/m2×24hr×atm; said multi-layer laminate having a moisture permeability of not more than 0.2 g×mm/m2×24hr×atm and an oxygen permeability of not more than 5 cc(STP)×mm/m2×24hr×atm. This multi-layer laminate has excellent gas-barrier properties and high rigidity. The present invention also provides a packaging material and a film using the multi-layer laminate.
