- Material: PO / PE film, 7–15dm (0.07–0.15 mm) — roll-fed
- Control System: Servo-driven tension control with precise heat-sealing
- Total Power: 30 kW (average) · Power Supply: 380V 3P 50/60HZ
Advantages & Features
- Patented Crease-Free (Waistline-Free) Forming Technology (Patent ZL 202521479001.6) – Breaking away from the inevitable waistline creases found in conventional paper bag production, the ZW-A11 adopts an innovative forming process that delivers perfectly smooth and flat bag bodies, free from any pressing marks. This significantly enhances the visual quality of the finished product, meeting the high-end retail packaging standards.
- Adjustable Single-Rail Gripper Conveying System (Patent ZL 202521479010.8) – Featuring a suspended gripper transport mechanism with automatic pitch adjustment according to sheet width, this system requires no manual intervention. It offers a compact footprint, stable operation, and is compatible with a wide range of bag sizes for high-speed production.
- Reinforced Rope-Threading with Folding Edge Bonding Technology (Patent ZL 202521479018.4) – The handle rope is securely bonded to both the folding flap and the bag body through a double-sided adhesion process, greatly enhancing the connection strength between the handle and the bag. This effectively increases load-bearing capacity, ensuring safety and durability during use.
- Inline Rope Quality Inspection System (Patent ZL 202521479019.9) – Each threaded rope is scanned in real-time during production, with defective bags automatically detected and rejected before entering subsequent folding processes. This prevents faulty products from progressing downstream, guarantees consistent output quality, and reduces manual inspection costs.
- One-Piece Local Folding & Gluing Unit (Patent ZL 202521479004.2) – The mouth-folding and gluing processes are integrated into a single station, enabling fully automatic one-step forming without manual assistance. This ensures uniform and neat folds with precise glue application, effectively improving production efficiency and product quality.
- Belt-Driven Mouth-Insertion Bonding Mechanism (Patent ZL 202521479003.8) – Utilizing a friction-belt drive system, this mechanism precisely inserts the inner side flap into the outer pocket, achieving a firm and flush seal. The resulting mouth closure is clean, secure, and free from misalignment or gap issues.
- Trace-Free Intelligent Bag Folding Unit (Patent ZL 202520425742.2) – By converting traditional dynamic folding into a static forming process, this technology completely eliminates scratches and creases caused by friction during bottom folding. The finished M-bottom is flawlessly flat and attractive, requiring no manual adjustment and enabling true “one-click size change” with “zero-trace folding.”
