It is a precision component composed of a high-strength glass fiber core layer bonded with a specialized food-grade/industrial-grade silicone coating. Its unique material and structural design are engineered to withstand the demanding requirements of heat sealing, cooling, and conveying processes in bag-making machines, serving as the “unsung hero” that ensures smooth production line operation.
Why is a silicone conveyor belt the ideal choice for bag production?
1. Exceptional Friction Drive and Stability
No slippage: The silicone surface delivers an extremely high coefficient of friction, ensuring perfect engagement with drive rollers for precise linear synchronization. This enables more accurate bag length control, fundamentally reducing size errors and scrap caused by slippage.
Exceptional dimensional stability: The integrated glass fiber layer prevents elongation and deformation during prolonged operation. This eliminates the need for frequent tensioning due to belt slack and completely prevents misalignment.
2. Superior Anti-Adhesion and Temperature Resistance
Non-stick surface: The silicone surface repels molten plastic films (e.g., PE, PP during heat sealing), effectively preventing adhesion and residue. This maintains a clean bag surface and reduces downtime for cleaning.
Temperature Tolerance: Maintains stable performance across a wide range from -60°C to 250°C, perfectly adapting to the high temperatures under the sealing blade of bag-making machines and the low temperatures in cooling sections. It will not harden, crack, or deform.
3. Product Protection and Clean Production
Gentle Handling: The soft silicone surface prevents scratching or abrasion of sensitive plastic film bags, ensuring flawless product surfaces.
Anti-static option: Special treatment can impart anti-static properties to the conveyor belt, preventing dust adhesion. This is particularly suitable for producing food bags and medical packaging bags with high cleanliness requirements.
4. Long-lasting Durability, Lower Total Cost of Ownership
Exceptional Wear and Tear Resistance: Compared to PVC or PU belts, silicone belts offer extended service life, withstanding prolonged continuous operation and mechanical abrasion.
Ozone and Aging Resistance: Maintains performance even in harsh industrial environments, reducing replacement frequency and lowering long-term maintenance and spare part costs.
