If you run an automatic zipper bag making machine (slider bag or press-to-close zipper bag machine), you know that the conveyor belt plays a critical role in output quality and uptime. A worn or jointed belt causes bag misalignment, zipper deformation, and frequent stops.
That’s why more production managers in Germany, Italy, and the US are switching to Annilte seamless silicone belts.
The Industry Pain Points You Face
- Belt joints create uneven surfaces → zipper sealing failure
- Sticking problems with hot melted materials → bag rejects
- Frequent belt replacement → high downtime & cost
- Poor heat resistance → belt hardening, cracks
- Inconsistent tension → bag length variation
How Annilte Seamless Silicone Belt Solves These Problems
- Truly seamless – no joint marks, perfectly flat running
- High-temp resistant – stable up to 200°C, no deformation
- Non-stick silicone surface – ideal for hot-melt zipper films
- Fatigue-free – lasts 3–5x longer than jointed PU or rubber belts
- Precise tension stability – consistent bag size, less waste
