Polyethylene or polypropylene

Not a fluorochemical

Base materials. Also written polyethylene, HDPE, LDPE, polypropylene, PP.

The two commodity plastics. Bottles, tubs, housings, films, non-woven fabric and filter media.

Neither is a fluoropolymer. The one PFAS angle with real evidence behind it is fluorination as a surface treatment on HDPE containers, which is a process applied to the finished bottle and not a property of the plastic, and nothing in our dataset records whether it was done.

What the makers actually said

Of the 139 graded products whose materials record polyethylene or polypropylene alongside a coating or finish, 98.6% name no coating chemistry anywhere in their published materials. This is a count of what companies published. It is not a statement about what any product contains.

A further 289 products record polyethylene or polypropylene with no coating or finish at all, so there is nothing for a maker to have disclosed. They are outside the split above.

Free to quote with a link. Of the 139 graded consumer products that record polyethylene or polypropylene together with a coating or finish, 98.6% name a coating chemistry anywhere in their published materials, according to PFAS Authority's October 2026 spec sheet decoder edition.

How those 428 products graded on our rubric

These are model-based estimates, not laboratory tests, scored on one public rubric. Read the spread against the categories underneath it rather than as a verdict on polyethylene or polypropylene in the abstract, because the rubric gives every category a baseline and a term concentrated in one category will carry that category’s spread with it.

Median grade 70 out of 100, across 45 categories.

Where polyethylene or polypropylene turns up

The 6 categories holding the most of it, out of 45. Each one links to the live ranking for that category, best graded first.

Best graded with polyethylene or polypropylene

One per category, best first, so the list is not five of the same thing.

Worst graded with polyethylene or polypropylene

One per category, worst first. A low grade here is usually something else on the product, not the term.

Decode a whole listing instead

A product usually names several of these at once, and the one that matters is rarely the one in the title. Paste the full materials line into the decoder and it will pick out every term it recognises, the most open-ended first.

Other base materials

Edition 2026-10-08, read from 11,337 graded products carrying a material string, and frozen at that date. A term is matched against the material and construction string recorded for each product, written from its published materials, specification and ingredient list rather than from a laboratory test. Products count under every term they match, so the totals across terms overlap. Found something wrong? Tell us.
