Alternative tapes for an impulse heat sealer that are PTFE free?

I have an impulse heat sealer and would like to know if there are any substitutes to the teflon tape that goes over the heating element. I have a bird and cannot use teflon (ptfe). 

Please don't suggest I get a constant heat sealer or use zip or flap bags.

    It’s probably a pretty unique situation, having a bird that close to a heat sealer. The PTFE tape is just fiberglass tape impregnated with PTFE to reduce friction. You can probably use something like 3M 361 glass tape as an alternative. It has a higher max temp than PTFE impregnated tape, which may be limited due to toxic off-gassing at higher temps.

    Teflon in the tape won't harm your bird.
