Perfect logic, but the fact remains that there isn't a glue for
poly[ethyl]ene, which isn't a million miles different from ptfe,
the
non-stick frying-pan stuff. It's always joined by welding. The
problem is, I think, that the adhesives on gaffer tape and
such-like,
while they will stick well to polythene till they dry out a few
years
later, can't be applied in amateur conditions.

Yup -but we are talking about repair -not construction.
A repair using the proper tape will outlast the useful life of the
poly sheet.
imho !

Yes, that's quite right; but I was only answering the question about
why we can't get an adhesive which would work for polythene.
