In the high-speed world of packaging, the "heat seal and cut" process is where quality is won or lost. If your conveyor belt can't handle the heat or if the plastic film sticks to the surface, your production line grinds to a halt.

Annilte Silicone Conveyor Belts (also known as Silica Belts) are engineered specifically for the packaging industry, providing a reliable, non-stick surface that thrives under extreme thermal stress.

The Heat Challenge: Why Standard Belts Fail

Standard PVC or PU belts often melt or become brittle when exposed to the thermal sealing bars of a bag making machine. Annilte’s specialized Silicone coating can withstand continuous operating temperatures of up to 250°C, ensuring your conveyor remains stable during the most intense production cycles.

Why Packaging Professionals Choose Annilte Silicone Belts?

1. Exceptional Non-Stick Properties

Plastic films like PE, PP, and BoPP become tacky when heated. Annilte’s silicone surface features unique release properties, ensuring that every bag releases cleanly from the belt after sealing. No residue, no jams, and zero downtime.

2. FDA-Grade Food Safety

Many bag-making machines produce packaging for the food and medical industries. Our silicone belts are made from 100% FDA-compliant materials, ensuring that no harmful substances migrate to the packaging material, keeping your products safe and compliant with international standards.

3. High Flexibility and Tensile Strength

Despite their heat resistance, our belts remain highly flexible, allowing them to run smoothly over small-diameter pulleys found in compact packaging machinery. The high-strength polyester or Nomex core ensures minimal stretching, even under 24/7 operation.

4. Precision Customization

We provide custom solutions for all types of packaging equipment:

• Red, White, and Blue Silicone options.
• Different Shore Hardness to match your film type.
• Seamless Loop construction for maximum joint strength.

FAQ: Scaling Your Packaging Production

Q: Does the silicone coating peel off over time?

A: No. Annilte uses an advanced vulcanization bonding process that chemically bonds the silicone to the base fabric, ensuring it won't delaminate even under constant thermal cycling.

Q: Can I get a sample for a heat-seal test?

A: Absolutely. We offer Free Samples for technical testing. We encourage our customers to verify the non-stick and heat-resistance properties in their specific environment before bulk purchasing.
