Hi Jill,
I am pretty sure that they are HDPE (high density polyethylene) and not UHMW. I am afraid your only choices are hot-air welding, or mechanical fastening (screws, bolts, rivets etc).Chris

Gluing UHMW has been reported successfully using Locktite 401 and 770 primer.
For polyethylene, 3M make Adhesives, Tapes, Reclosable Fasteners & Fabricated Parts : 3M. This is reputed to be 'satisfactory'.
Another type here - HDPE Glue | Innerduct.com
From what I have read over the years, if you invent or discover something that really works you are likely to be rich shortly thereafter. The industrial solution is to weld it.

I've only been able to get the Loctite and primer to work in static, low load, room temp situations. We always weld our pieces whenever we go outside those domain.
