Bag Making Operations TRIZ Cases

Separating gas filling and sealing into distinct stations reduces dwell time at each step, enhancing production capacity of the filling machine.

A film guide device suspends flexible web material between blade pairs to align side seals for accurate separation.

Sealing assembly fixes belt-shaped material before cutting to prevent tension-induced breakage in high-speed packaging lines.

Simultaneous welding and cutting via a servo-driven mechanism resolves sequential process bottlenecks to boost production throughput.

Composite multi-layer films absorb gas molecules to maintain freshness while minimizing plastic usage.

Liquid directing structures guide fluids away from vulnerable bag corners toward an absorbent insert, reducing leakage risks in thin film packaging.

A former with insert reduces wrinkles and tears by providing a smooth surface for packaging material flow.

Applying hot melt adhesive strips to tubular woven structures reinforces bag mouths, eliminating costly post-production overlocking steps.
