How can I best glue to polythene?
The polythene in question is dense and is taken from the nozzle of a
bottle. I need to glue it into place.
Of course I will key the polythene with many scatches but I need a
glue which will stick to it.
Will Araladite stick to polythene?
Will superglue stick to polythene?
More like least-worst, as in nothing is really good.
I have experienced the "hot melt" glues including/and the glues used in
glue guns to have some (but short of full) ability to stick to
polyethylene and the similar polypropylene.
Epoxy sometimes has ability to stick to (and with much less than normal
full ability) to polyethylene, and I suspect only that good to some grades
of polyethylene - there are different grades of polyethylene.
Please consider similarity of polyethylene to the similar (but even less
gluable) polytetrafluoroethylene, AKA PTFE, aka "Teflon" (I believe a
trademark of one of the more major manufacturers thereof) - famously

Is polythene the same as polyethylene?
Not knowing the answer to your question, I decided to do some research. A
great number of glues say they will not work on polyethylene. I only found
one that said it would; a 3M spray adhesive. But your application doesn't
sound right for a spray adhesive.
Some people say they have had success with hot melt glue. I tried it once
and it didn't work; but YMMV.

May not be relevant but:-
You can find worldwide very expensive LOCTITE glue (Loctite 406,20g),
and its primer (Loctite 770,10g) for soft plastics (polyethelyne).
Always wondered is polythene and polyethelyne the same thing.

It can, but you need to flame flash the surface first by passing the
flame from something like a propane torch over it briefly. Flashing
is a method of surface preparation for many low surface energy
plastics, such as polypropylene or polyethylene.
Surface energy defines the ability of adhesives to wet plastic
surfaces and allow adhesion. Surface wetting refers to how well a
liquid flows and intimately covers a surface.
Maximum adhesion develops when the adhesive thoroughly wets the
surface to be bonded. The better the wetting the better the surface
contact and the greater the attractive force between the adhesive and
the plastic surface.
Surfaces with low surface energy are more difficult to bond because
conventional adhesives cannot wet them resulting in minimal contact
with the plastic surface and unsatisfactory bonds.
If you put a drop of water on polyethylene it beads, if you put it on
the same surface after flame flashing it will spread. Once flashed
even cyanoacrylate (Superglue) will work successfully on
