Flexible Converting Architecture

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.

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.

Technical FAQ

Flexible Pouch Auxiliary Equipment — Frequently Asked Questions

Engineering specifications for high-speed film slitting, tension taper regulation, barrier film compatibility, and turnkey plant integration.

1. What core auxiliary equipment is required for an industrial flexible pouch production line?
A complete flexible pouch manufacturing line requires an upstream high-speed film slitting rewinding machine (ONL-SL F1300/F1600) to divide master extruded or printed rolls to precise pouch widths, a multi-layer dry or solventless laminating machine to combine barrier substrate layers, and a downstream pouch making machine (such as the OYANG 650 series) to seal, punch, and cut finished pouches.
2. What flexible packaging film substrates can the ONL-SL slitting machine process?
The ONL-SL series processes a wide variety of polymer and composite films, including biaxially oriented polypropylene (BOPP, pearlized BOPP), polyethylene terephthalate (PET), cast polypropylene (CPP), polyethylene (PE), polyvinyl chloride (PVC), metallized barrier foils (AL), self-adhesive label stock, and release liner papers.
3. What is the minimum slitting width and maximum roll diameter supported by the ONL-SL?
The ONL-SL accommodates a minimum slitting cut width down to 30 mm, making it suitable for narrow zipper strips and adhesive tape rolls, up to a maximum unwinding width of 1600 mm on the F1600 model. The maximum rewind package roll diameter reaches φ600 mm.
4. How does the ONL-SL film slitting rewinding machine maintain tension stability at 400 m/min?
The ONL-SL incorporates a 3-servo synchronous dynamic vector drive architecture paired with active low-friction dancer rollers and magnetic powder/servo brakes. A programmable tension taper curve automatically decreases rewind tension as the roll diameter expands from core Ø76mm to outer Ø600mm, preventing core crushing, web neck-in, and film elongation across thin 12–50 μm films.
5. What is the operational difference between razor blade and circular shear slitting?
Razor blade cutting is engineered for unprinted or plain flexible films like thin BOPP, PET, and PE, offering rapid knife positioning and low setup cost. Circular rotary shear slitting utilizes driven upper and lower dished blades with an 8% peripheral overspeed ratio, producing burr-free edges on thicker composite films, abrasive metallized barrier foils (AL), and release papers without generating dust.
6. How does the ONL-SL slitter interface with OYANG 650-series pouch making machines?
The ONL-SL functions as the upstream preparation center for OYANG 650S, 650SZ, 650SL, and 650QSB pouch making lines. By converting wide jumbo film reels into multiple narrow slit coils calibrated to exact pouch web specifications, it ensures continuous roll-fed conversion without edge curling, lateral skew, or tension dropouts on the pouch line.
7. When is a dry laminating machine required before film slitting and pouch making?
A dry laminating machine is required whenever the final package demands high oxygen or moisture barrier performance that cannot be achieved with a single polymer layer. Common laminated structures include PET/AL/PE for coffee packaging, BOPP/VM-PET/PE for snacks, and BOPA/R-PE for retort pouches. The lamination must cure completely before undergoing slitting on the ONL-SL.
8. What warranty coverage and field service does OYANG provide for flexible pouch auxiliary equipment?
All OYANG flexible pouch auxiliary units include a 1-year comprehensive mechanical warranty from installation sign-off, backed by a starter spare parts kit shipped inside the crate. Technical support is delivered by over 80 bilingual field service engineers and regional service centers in India and Russia, providing on-site commissioning and remote telemetry diagnostics.
