Identifying HDPE over UHMWPE

To identify these two materials can be difficult but a simple test using a 20 cent coin is a great start.

Simply drag a 20 cent coin over the materials sheet surface. If the 20 cent coin digs into the material leaving a jaggedindentationit's most likely HDPE

If using the same 20 cent coin over the sheet surface the coindigs in but flows smoothly over the sheet, then this suggests that it's UHMWPE
