So I'm getting out of melamine for my retic cages. I'm going to build them basically to the same specs. For my juvies up to about 8' I'm doing 1/4" polypropylene 48 x 24 x 24.
Anyway I'm wondering what the best polypropylene bond would be, and how it's used. I'd prefer to stay away from thermal welding if possible.

Thanks in advance for the advice.
