MULTILAYER LAMINATE AND USE

摘要

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 DEG C and RH of 0 %, of not more than 10 cc(STP).mm/m<2>.24hr.atm; said multi-layer laminate having a moisture permeability of not more than 0.2 g.mm/m<2>.24hr.atm and an oxygen permeability of not more than 5 cc(STP).mm/m<2>.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.
