Product Details

01.

Fully automated cutting, bottom sewing and edge-banding - processes laminated or non-laminated PP woven bags with 70-80% 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.

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.
