METHOD FOR LASER-MARKING LAMINATE FOR LID, LAMINATE FOR DISTRIBUTION PACKAGE LID AND DISTRIBUTION PACKAGE WITH MARKING

PROBLEM TO BE SOLVED: To provide a distribution package which is not exposed out of an outer surface of a distribution packaging bag, in which printed letters of a commodity name, a manufacturer symbol, a manufacture date or the like are not erased by external friction and which does not comes into direct contact with foods or the like as a packaged matter and further which facilitates reading. SOLUTION: The distribution package has a hard lid body which has a folding line having a half cut section formed from a surface side at a surface center part and a protrusion forming a discharge port when bent and a flexible container body which has a pocket for housing contents and a peripheral part of the flexible container body is welded to a rear surface of the hard lid body. The hard lid body is a hard composite laminate formed by laminating at least a surface layer, a hard intermediate layer and a seal layer at a rear surface of the hard lid body. The laminate and the distribution package are subjected to laser marking where a resin colored by pigment in the hard intermediate layer is turned black by carbonization caused by irradiation with laser beams and in this laser marking method, a font where a place of carbonization blackening is not irradiated again with laser beams is used.
