What are the best commercial adhesives for gluing polyester labels to
plastic? My application requires tolerance of temperature between -20 F
and +150 F.
This is a low volume application so I would appreciate commercial brand
names that could be purchased off the shelf.

What is the plastic? Should it remain flexible, like clothing?
Consider heat sealing. Or fabric cement from a sewing store.

The plastic is a clip on an insertable device, and it is rigid and probably
one half inch thick. It is not meant to twist or bend in the section that
is labeled.
I'm not sure of the exact type of plastic, but the part is clearly plastic
injection molded.

Insertable into what? A human body?

Therefore not epoxy, silicone, or Teflon
(DuPont brand, PTFE), right?
If you cannot answer all of those questions,
we can't help you. |

If it's molded, it's likely thermoplastic. You could use heat
sealing.
But if it's opaque and the surface is very smooth, it might be Delrin
or some similar plastic with poor adhesion qualities. Put a drop of
acid on the plastic. If it smells of formaldehyde, then it's Delrin.
You can roughen the surface with a short treatment with dilute acid.
If it's translucent, it might by polypropylene or polyethylene. In
that case, heat sealing is about your only option. I've had some luck
with hot-melt glue, even with Teflon, and you might want to try it.

Yep. Time to do some experiments and see what works.
PVC cement, perhaps thinned. (label may disintegrate)
Heat seal with a hot one-inch chisel point (a shaped die is better).
High or industrial quality double sided tape.

Can you explain the heat sealing process, and what do we buy for that?
I suspect the plastic we are using is a thermoplastic like ABS.
I guess it could also be a thermosetting plastic like any of these:
Melamine formaldehyde (MF)
Urea Formaldehyde (UF)
Polyester resin (PR)

The plastic is a solid gray, so definitely not a translucent material. It
is not opaque if by that you mean quasi-translucent but unable to see
through the material. It is smooth.
