Flexible Pouch Auxiliary Equipment Line
Engineered to eliminate roll telescoping, web neck-in, and edge curl on delicate barrier webs, OYANG's industrial flexible pouch auxiliary equipment synchronizes high-speed film slitting with multi-layer barrier laminating. Acting as an indispensable pouch making auxiliary machine line, our flagship ONL-SL series film slitting rewinding machine delivers line velocities up to 400 m/min with closed-loop 3-servo vector control and ultrasonic edge detection (±0.1 mm precision). Designed to convert BOPP, PET, barrier aluminum foils, and coextruded films down to 30 mm slit ribbons, this auxiliary family feeds defect-free, perfectly tensioned rolls directly into OYANG 650-series flat-bottom, stand-up doypack, and zipper pouch makers.
Flexible Barrier Pouch Production Sequence
From primary raw film extrusion to hermetically sealed pouches—how OYANG auxiliary systems synchronize across the converting plant.
Flexible Pouch Converting Machinery
Engineered for non-stretch precision across fragile polymer webs, metallized foils, and multi-layer composites.
Primary SlitterHigh-Speed Film & Label Slitting Machine
High-velocity slitter rewinder featuring 3-servo synchronous motor control for BOPP, PET, PVC, barrier aluminum foil, and release paper. Capable of continuous 400 m/min operation with zero web stretching.
Barrier BondingHigh-Speed Dry Laminating Machine
Precision roll-to-roll adhesive dry laminator designed for multi-layer barrier packaging (PET/AL/PE, BOPP/CPP, nylon retort films). Ensures uniform coat weight distribution without micro-tunneling or solvent retention.
Downstream Sync650SZLL Multi-Function Pouch Making Machine
High-speed multi-function pouch converting machine directly fed by the ONL-SL slitter. Operates up to 240 CPM, producing 3-side seal, stand-up doypack, and zipper barrier pouches under servo motion control.
Film Tension Stability & Rotary Shear Tolerance Matrix
In high-speed flexible pouch auxiliary equipment running thin extensible polymers (12 μm PET, 20 μm BOPP, or metalized foil), excessive rewind tension triggers web neck-in, core deformation, and roll dishing. OYANG ensures straight roll edges and dust-free slitting through verified mechanical tolerances machined across Japanese MAZAK and OKUMA five-axis machining centers:
| Auxiliary Subsystem | Engineering Tolerance / Control Spec | Shop-Floor Production Guarantee |
|---|---|---|
| 3-Servo Vector Tension Control | Web elongation < 0.02% across 12–50 μm films | Eliminates roll dishing and telescoping at 400 m/min, preventing register drift during downstream pouch converting. |
| Differential Air Friction Shaft | Segmented slip torque control (±0.05 N·m) | Compensates for multi-slit thickness variations across 1,600 mm widths, ensuring identical tightness on all rewind packages. |
| Rotary Shear Blade Assembly | Driven knife overspeed ratio: 1.08 × vline | Yields clean, dust-free slit edges on abrasive AL foils and thick laminates without micro-burrs or edge fusion. |
| MAZAK Machined Roller Spindles | Total Indicated Runout (TIR) ≤ 0.005 mm | Eliminates web flutter and optical scratches during ultra-high-speed transit, protecting high-barrier surface coatings. |
By coordinating ultrasonic edge guiding (CCD/Ultrasonic EPC ±0.1 mm) with dynamic low-inertia aluminum guide rollers balanced inside our 130,000 m² manufacturing park, OYANG flexible packaging auxiliary lines guarantee pristine reel quality for subsequent pouch forming.
Flexible Pouch Formats Fed by OYANG Auxiliary Slitters
The ONL-SL slitter outputs narrow barrier reels calibrated for high-speed automated forming across all major pouch geometries.
