Product descriptions from the supplier
1.Fully automated cutting, inner liner inserting, bottom sewing and top hemming - processes laminated and non-laminated bags with 75-85% labor reduction versus manual operations.
This device features fully automated ultrasonic sealing, folding the woven bag's edge inward as it welds the inner film to the outer woven material in one continuous motion.
3.Precision-length control: User-friendly touchscreen and servo motor system maintains ±1.5mm accuracy on every bag.
4.Switch seamlessly between cold-cutting (laminated bags) and hot-cutting (non-laminated) in under 1 minute.
Hot cutting bonds edge seams without sticking, enabling easy bag opening, whereas cold cutting produces neat, frayed-resistant finishes with no thermal warping—maintaining reliable results across both methods.
6.Automatic bottom sewing with dual-mode operation - choose to sew inner & outer bags together for sealed protection, or separately for replaceable liner flexibility.
Two separate, self-operating correction mechanisms work together to preserve accuracy for both the woven fabric and the inner layer, guaranteeing proper positioning, cutting down on raw material loss, and boosting overall output performance.
8.Automatic counting and stacking for seamless bag discharge.
9.Electric hoist-fed fabric roll system for effortless operation and labor reduction.
10.Handheld remote allows flexible control near the machine without touching the control panel.
