One of the side cases I got with my motorcycle has some fairly significant cracks, and the previous owner's shitty repairs were shitty and didn't work. I don't want to spend $500 on a replacement set of bags, and replacement parts are no longer available.

This piece is stamped with PP-TX20 which seems to mean that it's Polypropylene with some talc mixed in.

What would be the best way of repairing this for it to be reasonably strong and not look too too ugly?

It not so much being water tight that I care about so much as the structural integrity, this crack is right where the latching mechanism sits, I don't think I could tape it in a way to actually keeps it's shape since it's like right on a corner.
