I would be tempted to try epoxy, and maybe a mechanical fastener (screw)... Not much sticks to hdpe...

Three adhesives I might try are

Neoprene adhesive. Sticky as heck and stays flexible.

Or

Bridge deck epoxy. As in concrete bonding to steel for roadway bridges. There is a thermal bonding process so,if the plastic is too thin, it might warp or change shape. You could call a bridge construction company to see if they might sell you a small amount for a few dollars.

Or

Power or phone line cable epoxy. Designed to repair the sheathing and stay sealed in the nastiest of weather. It also needs heat to bond.

Lastly, you might write to CS at Nexabond and ask if they're 2500 product has any hope of working. I've used their woodworking glue to metal to glass and metal to wood with good success.

Not sure any of this is any help.

Be well,
Ben

Google "HDPE adhesive". It appears that while it was impossible to bond the stuff in the past, chemical engineers have recently cracked the code. There are articles from Henkel (Loctite), 3M, and several others on this subject. Presumably all touting their own new HDPE-compatible adhesives.

Thanks to all who responded.
This is part of a jig so it does need to be solid and permanent.
Thanks Dennis, I tried googleing before I posted here. Nothing I found appeared to meet the requirements of the job.
Guess I'll be screwing it.
Thanks again, guys.
