Product Description

1.Fully automated cutting, inner liner inserting, and bottom sewing - processes laminated and non-laminated bags with 70-80% labor reduction versus manual operations.
2.Precision-length control: User-friendly touchscreen and servo motor system maintains ±1.5mm accuracy on every bag.
3.Switch seamlessly between cold-cutting (laminated bags) and hot-cutting (non-laminated) in under 1 minute.
4.Hot-cutting seals edges without adhesion for smooth bag opening, while cold cutting delivers clean, fray-resistant edges with zero heat distortion - ensuring consistent performance in both modes.
5.Automatic bottom sewing with dual-mode operation - choose to sew inner & outer bags together for sealed protection, or separately for replaceable liner flexibility.
6.Dual independent deviation correction systems simultaneously maintain precision for both woven fabric and inner liner, ensuring accurate alignment, reducing material waste, and improving production efficiency.
7.Automatic counting and stacking for seamless bag discharge.
8.Electric hoist-fed fabric roll system for effortless operation and labor reduction.
9.Handheld remote allows flexible control near the machine without touching the control panel.
