What tape should I use for seal bars on a double chamber machine?

The Teflon cover tape we recommend is a zone tape, that has adhesive on each side and no adhesive in the middle. 

This zone tape allows air to create a gap between the heating element and Teflon tape, to prevent from over heating. 

The part number for our Teflon cover tape is KR9909999.

The insulater tape we recommend placing beneath the cut and seal wires on the bar itself. 

The part number for our Teflon insulate tape is KR990998.
