Product Description

1. Fully automated cutting with integrated bottom sewing - processes both laminated and non-laminated bags with 50% 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 deviation correction system - ensures precise production, reduces material waste, and enhances overall efficiency and product quality.
6. Automatic counting and stacking for seamless bag discharge.
7. Electric hoist-fed fabric roll system for effortless operation and labor reduction.
8. Handheld remote allows flexible control near the machine without touching the control panel.
