Designed to eliminate the severe bottlenecks of manual sheet-fed printing—such as web drift, inconsistent ink laydown, and ink chipping—OYANG's roll-to-roll screen printing machine series delivers continuous automated converting up to 3,000 m/h. Engineered for high-volume nonwoven packaging, this fully automatic screen printing machine line (ONL-12010 series) integrates ±75 mm electronic ultrasonic edge-guiding, pneumatic constant-pressure squeegee controls, and inline high-power infrared flash-curing tunnels to ensure thick, 100% opaque ink deposits on 45–100 g/m² polypropylene nonwoven webs with zero ink set-off before bag conversion.
Manual or semi-automatic sheet-fed screen printing methods suffer from erratic ink viscosity shifts, low speeds (< 300 bags/h), inconsistent operator pressure, and extreme fabric waste during manual positioning. On flexible spunbond nonwoven webs, uncontrolled fabric wandering leads to immediate registration loss across multi-color print designs.
OYANG ONL-12010 roll-to-roll screen printing machinery integrates an electronic edge guide system with ±75 mm dynamic travel, pneumatic friction brakes, and servo-synchronized reciprocating squeegees. Heavy-duty modular infrared and hot-air drying chambers flash-cure thick ink deposits within seconds, eliminating wet-ink set-off before roll rewind.
Choose between single-pass mono-color printing or inline dual-pass two-color printing engineered specifically for packaging bag webs.
Industrial roll-to-roll single color screen printing machine configured with 1 printing station and 1 hot-air infrared drying module. Operates at up to 3,000 m/h for high-throughput single-color supermarket bags and promotional sacks.
Fully automatic double color screen printing press configured with 2 printing units and 2 high-capacity infrared drying chambers in tandem. Completes dual-color registration in one automated pass at speeds up to 2,200 m/h.
Observe high-speed screen ink laydown, automatic edge guide tracking, and tunnel drying on roll-fed nonwoven substrates.

State-of-the-art sensors, edge guiders, and motion controls ensure zero fabric deviation during continuous converting.
Equipped with high-sensitivity ultrasonic/optical sensors maintaining ±75 mm correction accuracy. Actively eliminates lateral web wander at line speeds up to 3,000 m/h.
Real-time optical print mark registration monitors pattern alignment and ink coverage uniformity, instantly detecting misprints before fabric enters downstream bag makers.
Industrial PLC system precisely coordinates feed dancer rollers, squeegee stroke cycles, temperature profiles, and automatic rewinder tension curves through an intuitive HMI.
Evaluate ink deposit thickness, color saturation, and tooling overheads to select the optimum printing system for nonwoven bags.
| Technology | Optimal Applications | Wet Ink Thickness | Color Saturation | Fit for Nonwoven Bags |
|---|---|---|---|---|
| Screen Printing | Bold logos, solid text, promotional graphics | 10–30 μm (Thickest) | Maximum Opacity (100% cover on dark fabric) | Industry standard for D-cut, loop handle, and ultrasonic nonwoven box bags. |
| Flexographic Printing | Continuous web graphics, repeating patterns | 1.5–3.5 μm | Moderate Opacity | Excellent for high-speed multi-color (4–6 colors) long runs on paper and film. |
| Rotogravure Printing | Photographic image flexible packaging film | 1.0–2.5 μm | High Fidelity Gradients | Best for BOPP/PET film laminations, but plate cylinder cost is high for simple nonwoven logos. |
| Digital Inkjet | Variable data, low-volume custom samples | 0.5–1.5 μm | Variable (Requires primer) | Ideal for ultra-short runs; however, ink consumable cost is prohibitive for mass retail bags. |
Printed nonwoven rolls are directly converted on OYANG automatic nonwoven bag machines with zero ink chipping.
In an automatic screen printing machine, depositing thick ink films (10–30 μm) onto porous nonwoven fabric requires balancing downward hydraulic shear against fabric capillary strike-through. OYANG eliminates saw-toothed edges and fabric strike-through through closed-loop mechanical tolerances verified across Japanese CNC-ground guide ways:
| Deposition Subsystem | Engineering Tolerance & Settings | Shop-Floor Quality Impact |
|---|---|---|
| Squeegee Attack Angle (α) | 65°–75° Adjustable (75 Shore A Polyurethane) | Maintains hydrodynamic shear without blade flexing, guaranteeing sharp text edges down to 6 pt. |
| Pneumatic Squeegee Pressure | Constant-pressure closed loop (≤ ±0.1 bar) | Eliminates pinholes on textured nonwovens while preventing strike-through on lightweight 45 g/m² webs. |
| Off-Contact Distance (Snap-off) | 2.5–4.5 mm (Micrometer calibrated) | Provides instantaneous screen peel behind the squeegee line, eliminating web stickiness and ink ghosting. |
| Dual IR Hot-Air Drying Tunnel | Zone-controlled 60°C–90°C forced recirculation | Flash-cures thick ink films in under 4 seconds at 3,000 m/h, ensuring zero block-marking during rewinding. |
By coordinating linear servo traverse motion with rigid CNC machined carriage beams, squeegee deflection is held under 0.03 mm across the full 1,200 mm printing span, delivering 100% ink opacity across 24-hour nonwoven packaging runs.
