Sized for the FR-900 band sealer, this pack of 10 brown PTFE Teflon belts serves as replacement sealing and conveyor belts for continuous band sealing machines. The belts are thin brown endless loops bundled with a yellow tie. They carry the bag through the sealing section of the FR-900, and the heat-resistant PTFE belt material suits the continuous contact with the heating blocks during bag and pouch sealing.
