How about aluminum 'duct' tape for shielding? What are the differences compared to copper tape?
It works ok (skin depth isn't much different), but the real issue is that usually, the adhesive is not conductive.? Folks use this to make toroids for Tesla Coils, but in that application, the HV punches right through the adhesive. And, the fact that aluminum has an insulating surface film makes it tough to make good seams. However, if you do a rolled & crimped seam (hard to draw with text), it can work ok (because that makes the "slit" very long).
I've not had good luck at UHF and up, and haven't tried at lower frequencies.
The real problem is the aluminum oxide film, though.

Self-adhesive copper foil may be alternative that offers better shielding. I have used it on many plastic enclosures. I can solder bridge between sheets to cover areas wider than 4 inches.
