This integrated packaging line consists of ZRB-500G Full-Automatic Sleeve Wrapper and DRS-4522 Intelligent Visible Variable-Frequency Heat Shrink Tunnel, seamlessly connected to deliver a complete unmanned packaging solution covering automatic feeding, sleeve film wrapping, pulse cold sealing & cutting, continuous heat shrinking, and precise discharging. No manual transfer or intermediate operation is required during the whole process.

Compatible with PVC and POF heat shrink films, the line reaches a maximum packaging speed of 28 packs per minute, delivering neat sealing edges and uniform wrinkle-free shrinking results. It is widely applied for single or multi-pack shrink wrapping of adhesive tapes, daily chemicals, food, cosmetics, gifts, toys and other products.

Automatic feeding → Product positioning & alignment → Automatic sleeve film wrapping → Pulse cold knife sealing & cutting → Automatic transfer to shrink tunnel → Uniform hot air circulation shrinking → Precise discharging → Finished packs

Fully continuous automatic operation without manual intervention between processes.

• Pulse Cold Sealing Technology: 500mm effective width pulse cold sealing cutter, no preheating required, instant start-up, low energy consumption, delivers smooth, scorch-free sealing edges without film sticking.
• One-Button Size Adjustment: DC motor driven width/diameter adjustment with precise positioning, fits products of Ø40-160mm diameter and 40-350mm width, supports single/multi-piece packaging; one-button specification changeover without manual debugging.
• High-Speed Stable Performance: Max speed 28 pcs/min; full steel frame ensures stable, low-vibration long-time operation.
• Precise Conveying: Automatic conveyor feeding, split design for easy logistics and installation; storage-type film feeding system prevents film misalignment; precise discharge positioning ensures tight packs without loosening.
• Exclusive Anti-Adhesion Design for Tapes: Special separation structure completely eliminates adhesion between tape rolls, ensures smooth pushing without jamming.
• Seamless Integration: Directly connects with rear shrink tunnel, also compatible with automatic slitting machines for fully unmanned operation.

• Energy-Saving Insulation: High-temperature resistant rock wool insulation layer reduces heat loss and keeps low surface temperature; stainless steel heating tubes ensure extra-long service life.
• Uniform Hot Air Circulation: Custom air duct system with dual high-power imported motors delivers adjustable, even air volume inside the tunnel, ensures uniform heating, no cold spots or wrinkles, film tightly fits products.
• Durable Construction: Outer panels: bent carbon steel with plastic-sprayed finish; inner panels: hydraulically formed galvanized steel, heat-resistant, corrosion-resistant and easy to clean.
• Intelligent Visible Control: Observation window + variable-frequency speed control (0-15m/min adjustable) for real-time shrinking status monitoring; chain rod conveyor with max 30kg load capacity runs smoothly without slipping.
• Safety Protection: Equipped with phase failure/sequence protector and constant temperature controller for low-failure stable running.

1. Labor Saving: Automatic connection between sealing and shrinking processes saves 2-3 operators per line by eliminating manual transfer and arranging.
2. Matched High Efficiency: Front sealing speed (max 28 pcs/min) perfectly matches rear conveyor speed (0-15m/min adjustable), no stacking or jamming, stable running speed 23-28 pcs/min.
3. Consistent Packaging Quality: Linked parameter control delivers uniform neat packs, avoids film offset and loose packs caused by manual transfer.
4. Easy Operation: Centralized parameter control, one-button synchronized size changeover for both units, no separate debugging required, easy for new operators.
5. Reliable Durability: Core components from famous brands (Schneider, IDEC, Taiwan Yangming, NSK/HRB bearings, etc.) and full steel frame ensure low failure rate and long service life.
6. Flexible Installation: Split design of sealer, conveyor and shrink tunnel for convenient transportation and workshop layout adjustment.
