PURPOSE:To obtain a satisfactory adhering strength for a metal deposited face by forming a specific ethylene.ethylene unsaturated carboxylic acid.ethylene unsaturated carboxylic acid ester copolymer layer on the metal deposited face of a metal deposited polypropylene film. CONSTITUTION:Ethylene unsaturated carboxylic acid content of ethylene.ethylene unsaturated carboxylic acid.ethylene unsaturated carboxylic acid ester copolymer must be 2 - 8wt.%, and ethylene unsaturated carboxylic acid content must be 5 - 25wt.%. The melt flowrate of the copolymer (190 deg.C, 2,160g load) must be in a range of 5 - 50dg/min. A packaging multilayer film can be manufactured by extrusion laminating the copolymer on the deposited metal face of the metal deposited polypropylene film. |
