Product Details

01.

Fully automated cutting, inner liner inserting, bottom sewing and edge-banding - processes laminated PP woven bags with 75-85% labor reduction versus manual operations.

02.

It enhances seam sealing by applying an adhesive tape (hot-melt or cold glue) over stitched seams, with optional heating for thermal-bonding tapes.

03.

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

04.

Cold cutting provides clean, fray-resistant edges with no heat distortion, ensuring consistent performance.

05.

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

06.

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.
