Product Details

01.

Fully automated cutting, inner liner inserting and bottom sewing - processes laminated and non-laminated bags with 70-80% labor reduction versus manual operations.

02.

Automatic bottom sewing with dual-mode operation - choose to sew inner & outer bags together for sealed protection, or separately for replaceable liner flexibility.

03.

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.

04.

Precision-length control: User-friendly touchscreen and servo motor system maintains ±1.5mm accuracy on every bag.

05.

Switch seamlessly between cold-cutting (laminated bags) and hot-cutting (non-laminated) in under 1 minute.

06.

Hot cutting seals edges without adhesion for a smooth bag opening, while cold cutting provides clean, fray-resistant edges with no heat distortion, ensuring consistent performance in both modes.
