Yes it can be glued with difficulty. A PHD student I lodged with at
Uni had
to make chemical preparation apparatus out of polythene due to the
strange
chemicals he was working with (?). Problem with polythene is it is
"oily"
and most glues won't stick.

He assembled is apparatus either by friction welding, rotate one
piece in
fast and force onto other piece

or hot air gun and plastic rod

or finally etching surface with chromic acid (nasty stuff) to produce
a
"crust" which can then be glued.


nice explanation of best methods there. The usual home method is by
melting it, either with a heat sealer or for heavier lumps, a heated
pin.
