Has anyone got a labelling machine that can do plastic labels that will
withstand outdoor use?

There are two types. some hotfoil the print onto the outside of the
plastic substrate, others transfer it to the middle of a
clear-print-background sandwich.

I have used the second type, a Dymo 4500, to label subsea equipment
towed through the ocean at up to 6 knots. If it can survive that it
can survive anything.

That said, the only really indestructable labels appear to be embossed
metal. I have used stainless and aluminium strip - the stainless has
sharp edges.
