Advantages & Features
- Patented Crease-Free (Waistline-Free) Forming — Unlike conventional paper bags that leave visible waistlines, ZW-A11 produces clean, smooth bag bodies for a premium retail appearance.
- Adjustable Single-Rail Gripper Conveying (Patent ZL 202521479010.8) — Suspended transport with grippers whose spacing auto-adjusts to sheet width, compact in footprint and stable across varying bag sizes.
- Reinforced Rope-Threading with Folding Edge (Patent ZL 202521479018.4) — The rope is bonded on both faces to the folding flap and bag body, significantly increasing handle and bag load-bearing strength.
- Inline Rope Quality Inspection (Patent ZL 202521479019.9) — Each threaded rope is scanned in real time; defective bags are automatically diverted from downstream folding, ensuring consistent output quality.
- One-Piece Local Folding & Gluing (Patent ZL 202521479004.2) — Automated mouth-folding and gluing eliminates manual operation and guarantees uniform fold quality.
- Belt-Driven Mouth-Insertion Bonding (Patent ZL 202521479003.8) — Friction-belt mechanism precisely inserts the inner side flap into the outer pocket for a clean, secure mouth seal.
- Trace-Free Intelligent Bag Folder (Patent ZL 202520425742.2) — Converts dynamic folding into static folding, avoiding friction marks and producing a flawlessly flat, attractive M-bottom bag — no manual adjustment required.
