Silicone conveyor belts excel at overcoming various challenges in zipper pouch production with their outstanding performance, offering advantages unmatched by traditional conveyor belts.

 

Exceptional Anti-Adhesion Properties

One of the most common issues in zipper bag production is melted plastic and zipper materials adhering to the conveyor belt surface. Silicone's inherent anti-adhesion properties ensure bags release effortlessly during transport, completely eliminating:

 

Bag tearing or deformation caused by sticking;

Frequent downtime for residue cleanup;

Waste resulting from damaged products.

 

Outstanding High-Temperature Resistance

Zipper bag production involves high-temperature sealing and heat-pressing operations. Silicone conveyor belts can continuously withstand temperatures (often exceeding 200°C) without deformation, cracking, or aging. This thermal stability ensures long-term, stable equipment operation in high-heat environments.

 

Exceptional Durability and Service Life

Silicone material exhibits outstanding resistance to abrasion, tearing, and mechanical stress. Its lifespan significantly exceeds that of PVC and fiber belts, substantially reducing replacement frequency and maintenance costs while minimizing production downtime risks.

 

Precise Grip and Stability

High-quality silicone conveyor belts feature a surface with moderate tackiness, ensuring zipper bags remain securely positioned during sealing and cutting processes to prevent slippage or misalignment. This stability guarantees precise forming and cutting for every bag, significantly reducing defect rates.

 

Easy Cleaning and Maintenance

The smooth, non-porous silicone surface facilitates effortless cleaning. Residues wipe away easily, maintaining a hygienic production environment while meeting stringent sanitation standards for food and medical product packaging.
