A recyclable cushioning material for packaging obtained by forming a cushioning material for packaging used to protect articles supplied for physical distribution from being impacted with one sheet of corrugated fiberboard and a method and device for manufacturing the cushioning material, wherein a plurality of cutting lines (11 to 21) are formed in one sheet of corrugated fiberboard (10) in parallel with each other in the direction perpendicular to a direction in which the pleats of the corrugated fiberboard extend and a plurality of connection parts (25) are formed intermittently on each of these cutting lines so that a plurality of unit corrugated fiberboard (41 to 52) can be folded up alternately each other, openings (30 to 33) including the cutting lines are formed in the plurality of unit fiberboard (46 to 52) located on the inner side, and zig-zag foldings at the cutting lines (11 to 21) in which hump-folds and trough-folds are formed alternately each other are performed simultaneously by a zig-zag folding device (70), and the pleats are glued with gluing nozzles (82, 83) and pressed by a cylinder (87) so as to connect and stack the unit corrugated fiberboard (41 to 52) to each other, whereby the cushioning bodies for packaging (57 to 60) formed of a corrugated fiberboard stacked body having an article supporting part (55) can be assembled automatically.
A cushioning material for packaging comprising a corrugated fiberboard laminated body formed by mutually oppositely folding, and laminating and joining a plurality of unit corrugated fiberboard (41-52), the plurality of unit corrugated fiberboard being formed with a blank (10) made of a sheet of corrugated fiberboard, the blank having a plurality of parallel folding lines for partitioningthe sheet of corrugated fiberboard into a plurality of unit corrugated fiberboard and openings (30-33) for receiving an article, the plurality of unit corrugated fiberboard being inter-coupled through the folding lines,
A manufacturing method of a cushioning material for packaging comprising the steps of:
A manufacturing device of a cushioning material for packaging for manufacturing the cushioning material for packaging from a blank made of a sheet of corrugated fiberboard including a plurality of parallel folding lines for partitioning a plurality of unit corrugated fiberboard and openings for receiving an article, said manufacturing device comprising:
