High-Temperature Resistant Silicone Conveyor Belt for Bag Making Machines | Annilte


At Annilte, we specialize in manufacturing high-performance silicone conveyor belts for bag machines. Our belts are engineered to meet the rigorous demands of modern bag production, ensuring you get a perfect seal every time.

Why Silicone? The Critical Advantage for Bag Making

When running a bag machine, particularly during the heat sealing process, standard PVC or rubber belts simply fail. Here is why silicone is the industry standard:

  • Exceptional Heat Resistance: Bag making machines require sealing jaws to operate at high temperatures (often 150°C to 250°C+). Annilte silicone belts maintain their integrity, resisting hardening and cracking even under continuous high heat .
  • Non-Stick Surface: One of the biggest pain points in bag production is melted plastic sticking to the belt. Our silicone material has natural release properties, preventing residue build-up and ensuring clean, professional seals.
  • Food Grade Compliance: If you are producing bags for food packaging, hygiene is paramount. Our silicone belts are made from FDA-approved, odorless, and tasteless materials, making them safe for direct contact with consumables .

Solving Industry Pain Points: The Annilte Difference

We understand the specific challenges faced by operators of bag making machines. Here is how Annilte addresses them:

1. The Pain: Frequent Belt Replacement Due to Edge Wear
Many bag machines involve sharp sealing knives or serrated cutters. If your belt wears out at the edges quickly, it disrupts production.

  • Annilte Solution: Our belts feature a high-density woven structure combined with a specialized silicone coating. This provides superior cut and tear resistance, extending the lifespan of your belt significantly compared to standard options.

2. The Pain: Belt Tracking Issues (Slippage and Misalignment)
If your belt wanders left or right, it causes misfeeds and jams.

  • Annilte Solution: We ensure precise tolerances in manufacturing. Our belts offer excellent dimensional stability and can be customized with V-guides or reinforced with Kevlar cords to maintain perfect tracking on high-speed machines.

3. The Pain: Seam Marks on Finished Bags
For aesthetic quality, a seamless belt is often required to prevent bump marks during sealing.

  • Annilte Solution: We offer endless (seamless) silicone belts manufactured through a cold bonding process. This creates a smooth, flat surface that ensures no impression is left on your delicate film .

Compatibility with Leading Bag Machine Brands

Your machinery is an investment. Annilte belts are designed to be the perfect retrofit or OEM replacement for a wide range of international and domestic bag machines. We are the preferred choice for operators of:

  • Japanese Machines: Newlong (NPI), Totani
  • Taiwanese Machines: Chyi Yang, H.S. Industries (HSI)
  • European Machines: Holweg Weber, Leetro
  • Chinese Machines: Ruian Zhengxin, Wenzhou Qiangxin, and various local manufacturers.

No matter the model, we can customize the belt dimensions (thickness, length, width) to meet your exact specifications.
