PTFE Sealer belts

PTFE Sealer Belts – PTFE Sealer belts are ideally suited where thermal transfer through the surface of the belt is required in order to seal plastic materials.


Companies manufacturing packets of biscuits or toilet rolls would normally use these belts in order to seal the ends of the packets.

Sealer belts tend to be two belts that run in tandem on the conveyor with a hot-plate that sits in contact with the inside of the belts as they run. The heat transfers through the belts surface to the packet, sealing the plastic wrapping as it conveys it through the machine.

Features / Benefits

The belts run with tracking studs inserted in to one edge of the belt that then locate in to a machined grooves in the rollers of the conveyor. This prevents the belts from tracking off and extends the belts life. Over more recent years as machines have developed we are seeing less and less metal tracking studs being used. Instead belts are being made with a raised edge surface down both outer edges of the belt. this overhangs the roller and keeps the belt in position.

The premium grade PTFE used to manufacture the belts has a non stick, high temperature resistant surface that prevents any molten plastics from building up on the belts surface. We tend to supply these belts our tear resistant product as this can prolong the working life of the belt. The nominal thickness is 0.15mm and has a coated weight of 300 grams per square meter.
