What bag types can this machine produce?

The flat bag making machine produces flat bags, bottom-seal bags, and side-seal bags – used for shopping bags, garbage bags, produce bags, and general-purpose packaging bags.

What is the maximum film thickness?

Standard models handle up to 0.15mm film thickness. Heavy-duty models handle up to 0.25mm for industrial-grade flat bags.

Can it produce multiple lanes simultaneously?

Yes. Multi-lane configurations allow simultaneous production of multiple bags in parallel – significantly increasing output for high-volume orders.

What is the sealing technology?

Our machines feature multi-zone temperature control (±1°C) with impulse or continuous sealing – ensuring strong, leak-proof seals with clean, aesthetic appearance.

Does it have automatic stacking?

Yes. The machine features automatic counting and stacking – bags are neatly stacked and layered by preset quantity, ready for packaging without manual sorting.
