PROBLEM TO BE SOLVED: To prevent cargos from collapsing by sliding when stacking rice bags in a multiple stages by processing print showing surfaces applied to outer surfaces of rice bags of polyethylene film and providing a settling feeling, a texture feeling, and a high quality feeling.SOLUTION: An elongate tube body (1) is shaped of a polyethylene film, a substrate printing layer (3) is formed in a front surface part (2') including a side surface part (2n') of a flat body (2) constituted by forming the tube body flat, a brand and an area of production of a product are shown in the substrate printing layer, and a mat coating layer (4) is formed in the substrate printing layer (3), an indication based on JAS and an indication based on a PL law are printed in a rear surface of the flat body, the flat tube body (2) is cut in a predetermined length in a longitudinal direction, and a unit bag body (A) is shaped after forming the mat coat layer (4) in the substrate printing layer (3). |
