Japanese Bottom Paper Bag Machines

Japanese bottom paper bag production requires the tube dimensions, crease position and bottom preparation to match the final folding method. CHAMPION configures sheet-fed feeding, pasting and tube forming equipment around the buyer’s sample so downstream bottom work can remain stable and repeatable.

The finished bag sample should show bottom fold direction, gusset, overlap, reinforcement and handle position.
Pre-printed sheet accuracy and paper surface characteristics must be confirmed before selecting feeding and gluing systems.
Production capacity should be evaluated across the complete workflow rather than using only the nominal speed of one machine.

Buyer Questions

What makes a Japanese bottom bag different?

Its bottom folding and closing method differs from common square or V bottom structures, so the tube and crease preparation must match the final bag design.

Can CHAMPION confirm the process from a finished sample?

Yes. A finished bag, unfolded sample or detailed drawing helps engineers confirm feeding, tube forming, gluing and downstream bottom requirements.
