Can Kombucha leather be heat-sealed?

Hey guys,

I’ve been seeing a lot of small studios that work with kombucha leather in specific make packaging that is heat sealed, like regular packaging plastics.

Does anyone here know how this works?
I tried heat-sealing a very thin, dry SCOBY sheet that was treated with a bit of beeswax + coconut oil. There were very slight burn lines but no heat seal.
Is there some additional post-processing done to dry SCOBYs to allow edges to be heat-sealed? Is there a specific heat setting or type of sealer needed for this?

I assume studios don’t share their exact processes because of IP or R&D rights but if this is information people are generally aware of and don’t mind sharing, please do!
