Product DNA: Unbreakable Seals at Speed

Shanghai Guangzhi’s Model Band Sealer revolutionizes high-volume bag sealing with continuous-motion technology. Engineered for LDPE, PP, aluminum foil, and multi-layer laminates (50-500mm width), it achieves factory-hardened seals at 100+ bags/hour – ideal for granular foods, pet kibble, powders, and industrial chemicals requiring hermetic closure.

Continuous Band Sealer

Engineered for Demanding Lines

1. Precision Thermal Control

  • Dual PID Zones (±1°C accuracy): Separate control for top/bottom belts

  • Temp Range: 30-250°C (handles heat-sensitive films to thick laminates)

  • Cooling Zone: Compressed air jets set molten seals in 0.8 seconds

2. Teflon-Reinforced Durability

  • Heavy-Duty Belts: Teflon®-coated glass fiber belts (10x longer life)

  • Zero Film Tear: Spring-loaded tension control & belt tracking

3. Production-Proof Performance

  • Seal Strength: 20N/15mm (exceeds ASTM F2029)

  • In-Line Speed Sync: 0.5-15 m/min adjustable to conveyor lines

  • 24/7 Readiness: Dust-proof motors & overload protection
