<p>PURPOSE:To eliminate an elongation on a printing design with an equal interval part and to obviate wrinkles at the time of laminating by thermally contact- bonding an olefin polymer long printed matter on a specific ethylene copolymer layer, and laminating it at a temperature higher than the thermally contact- bonding temperature and not melting the specific polymer. CONSTITUTION:An ethylene copolymer layer of a long laminated matter made of a layer of olefin polymer and a layer of ethylene copolymer of ethylene having a melting point of 20 deg.C or lower measured by a differential scanning calorimeter from olefin polymer and ethylene unsaturated monomer containing an epoxy group or ethylene polymer of them and vinyl ester and/or unsaturated carboxylic acid ester is heated to 40 - 100 deg.C, a long matter of olefin polymer printed in advance is heated to its temperature range to be thermally contact- bonded to the ethylene copolymer layer, the thermally contact-bonded matter is further thermally press-bonded and laminated at a temperature higher than the thermally contact-bonding temperature and not melting the ethylene copolymer. A printing design has no elongation as compared with an original printing plate long printed matter with an equal interval part, and no wrinkle occurs at the time of laminating.</p> |
