Not sure if it's polyethylene, but it's about 5-10um thick.
Have already tried this for tesla caps, including many, many layers.
No good I'm afraid - high frequency seems to kill it...

Yes, certainly... however, Caterer's foil (0.3mm thick) is much better.
It's thicker, stronger, smoother and much, much higher quality...
Take a look around for Capril Caterers Foil - found in a few aluminium
shops...
You may like to try the Polythene film (Cromfords) available from Mitre
10, or BBC for around $8 for a 2m x 5m roll - use the clear stuff only.
