HDPE 3D Printer Filament Substitute


So I'm working on a prototype for my design but the final product will more than likely be made of High-Density Polyethene. The problem is that HDPE is SUPER difficult to print with and very difficult to even find. I am wanting to know if anyone has any good substitute ideas that would be similar to HDPE? I've already bought TPU filament but was wondering if there were any other ideas. The main component needed is a plastic that is thin yet flexible.
