PROBLEM TO BE SOLVED: To provide a packaging structure and a packaging method for lithographic printing blocks which can package a loading bundle of a large number of the lithographic printing blocks with a simple structure, and easily package and unpackage the loading bundle. SOLUTION: The loading bundle 12 with the lithographic printing blocks and slip sheets alternately loaded is placed on a pedestal 18 with a protective sheet 22 and a shrink film 38 placed thereon, and the protective sheet 22 is placed on a top surface. A light-shielding and humidity-proof material 16 is wound so as to cover the whole side of the loading bundle 12 and the protective sheet 22, the shrink film 38 is further arranged on the side surface and the top surface, heated in a heating box 50, and then, cooled at room temperature. The shrink film 38 is shrunk, and the light-shielded loading bundle 58, the protective sheet 22 and the light-shielding humidity-proof material 16 are bundled. A conventional corrugated fiberboard or an end plate can be dispensed with, and the packaging structure 30 is simplified, and at least a part of the packaging work can be automated using a packaging machine. |
