The present invention relates to a manufacturing method of an assembly-type box for packaging agricultural and marine products. The manufacturing method comprises: a sheet molding step (S1) for molding a sheet by foaming polypropylene (PP) or chemically cross-linking high-density polyethylene (HDPE); a sheet cutting step (S2) for supplying the sheet to a mold having the fixed shape, and compressing and cutting a body composed of a cover surface in the mold; a coating member molding step (S3) for extrusion molding the outer layer of a film with random polypropylene (RPP), extrusion molding a core layer with the film by missing mLLDPE and the polypropylene (PP), and extrusion molding an inner layer (130) with the film mixed with the random polypropylene (RPP), mLLDPE, and EVA; and a coating step (S4) attached to be integrated with the body and the coating member, for providing a folding blockage protrusion unit in an exposed state. |
