Rather than roll the dice on yet another Chinese vendor… I'm taking a different tack.
I've acquired a roll of 0.3mm PVC.

It's a 3½m roll of the stuff, 1370mm wide. Should be enough.
There are five possible ways I can join pieces of it:
- sew it, then use seam sealer (as suggested by @ai6yr@m.ai6yr.org)
- glue it / chemical welding (what I was thinking of initially)
- thermal welding
- ultrasonic welding
- RF welding
Whilst I have devices that can put 100W of RF anywhere between 1.8MHz and 29MHz… I don't think my radio finals will take too kindly to this sort of abuse… and a RF welding rig is likely well outside my price range.
Ultrasonic rigs are up around the AU$700+ mark… pricey for a one-off.
Thermal welding rigs need to get to 300°C… soldering iron territory. I have an old Jaycar one that has temperature control and a somewhat buggered tip. Might be an option here.
I'll try a small sample of material and see what works.

Plastic bag sealer.

(Can't verify quality or electrical safety of this one. Seems very cheap)
Back in 1990 was part of the Young Archivers program. About 25 students from various a schools, were teamed up with a company for guidance and you would run your own company, sell shares, make a product etc.
Someone had the idea of turning excess plastic our host company had lots of, into plastic punchos. Like the thin disposable ones, but thicker.
Used a thermal bag sealer for straight sides, but the hoods were curves. I think we sewed them together.
