PTFE bag sealing belts

SKU: BEL005

PTFE bag sealing belts are ideally for applications where thermal transfer through the belt surface is required to seal plastic bags.

High volume bag manufacturing systems often use these types of belts running as a pair creating a clamping effect on the bag. These belts can also be found on air fill or air cushioning packaging machines as a means of allowing continuous heat sealing to take place without molten plastic sticking to the belt.

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 sealing the plastic bag as it conveys it through the machine.

Constructed with two layers of PTFE coated glass cloth laminated together they benefit from being free of any step at the joint area that could leave a mark.

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 belt's surface.
