PTP or blister packaging articles and packaging material therefor

摘要

A sheet or film for PTP or blister package having excellent moisture resistance and transparency and readily prepared by vacuum or pneumatic forming comprises a layer made of at least one non-crystalline polyolefin resin selected from (A-a) a cycloolefin random copolymer which is made from ethylene and a cycloolefin having a specified general formula and has an intrinsic viscosity [ eta ] of 0.01 - 10 dl/g determined in decalin at 135 DEG C and a softening temperature (TMA) of 50 - 200 DEG C, (A-b) a (co)polymer, obtained by a ring-opening polymerization of the cycloolefin or a hydrogenation product thereof, which has an intrinsic viscosity [ eta ] of 0.01 - 10 dl/g determined in decalin at 135 DEG C and a softening temperature (TMA) of 50 - 200 DEG C, and (A-c) a graft-modified product of said cycloolefin random copolymer (A-a) or said ring-opening (co)polymer or its hydrogenation product (A-b).
