If you operate a bag making machine—whether for zipper bags, side-seal bags, or form-fill-seal applications—you know the frustration all too well. Melted plastic sticking to the belt. Frequent cleaning stops that kill your OEE. Inconsistent seals that lead to bag rejects and customer complaints. Belt tracking issues that cause misalignment and jams.These aren't just minor annoyances. They're profit killers.
At Annilte, we've spent 17 years engineering solutions for these exact problems. Our seamless silicone conveyor belts are purpose-built for the extreme demands of bag making machinery—and they're trusted by 18 Fortune 500 companies and over 20,000 customers worldwide .
The Industry Pain Points You Face Every Day
| Problem | Impact on Your Production |
|---|---|
| Jointed belts create uneven surfaces | Bumps cause sealing failure, bag misalignment, and zipper deformation |
| Molten plastic sticks to the belt | Frequent cleaning stops, bag rejects, and contamination |
| Poor heat resistance | Belt hardening, cracking, and premature failure under sealing temperatures |
| Inconsistent tension | Bag length variation and registration errors on printed film |
| Frequent belt replacement | High downtime and maintenance costs |
How Annilte Seamless Silicone Belts Solve These Problems
1. Truly Seamless—No Joint Marks, Perfectly Flat Running
Unlike spliced belts that create a "bump" with every rotation, our seamless molded construction ensures a perfectly smooth surface. This eliminates vibration and joint marks, giving you consistent seal quality and precise bag length every time .
2. Unmatched Heat Resistance—Up to 300°C
Standard rubber or PVC belts degrade at 80–100°C. Annilte silicone belts maintain their integrity at continuous temperatures from -60°C to 260°C, with instantaneous tolerance up to 300°C—far exceeding the sealing demands of bag machines .
3. True Non-Stick Performance
Our food-grade silicone surface has an inherent release property. Molten polyethylene, adhesives, and residues simply peel off—with a residual rate of less than 0.1% . This means:
- 70–80% reduction in cleaning downtime
- Zero contamination on your finished bags
- Cleaner, more professional seals
4. Built to Last—3–5x Longer Than Standard Belts
Our belts feature a reinforced fiberglass core and full-thickness silicone compound—not just a thin surface coating that wears off. Customers report 40–60% longer service life compared to previous belts, drastically reducing replacement frequency and costs .
5. Precision Tracking for Registration Accuracy
Dimensional stability ensures your belt runs true without wandering—critical for pre-printed film where print-to-seal registration must be perfect . We can also customize with V-guides for exact OEM fit.
