PROBLEM TO BE SOLVED: To realize a returnable package which can be reused by easily repairing a damage if the damage is partial. SOLUTION: This returnable package 1 is constituted of a molding 10 for which a thermoplastic resin 3 is mixed in a main raw material of a paper-based raw material 2. For the molded body 10, the thermoplastic resin 3 is uniformly mixed so that the thermoplastic resin 3 may be softened by being heat-pressed later, and may be re-hardened by natural cooling. Thus, if a damage is partial, this returnable package 1 can easily be repaired by heat-pressing the damaged location 5. COPYRIGHT: (C)2007,JPO&INPIT
