Grease resistant paper or moulded fibre

Chemistry not stated by the term

Coatings and finishes. Also written grease resistant, greaseproof, oil resistant paper.

Paper, board or moulded fibre treated so fat does not wick through it. Food wrappers, bakery liners, takeaway boxes and bowls.

Fluorochemical sizing was the standard way to do this for decades and is the exact application several state laws on our timeline now restrict by name. Alternatives exist, including clay and plant based barriers and simple lamination, and the label rarely distinguishes them.

What the makers actually said

Of the 388 graded products whose materials record grease resistant paper alongside a coating or finish, 99.2% 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.

How those 392 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 grease resistant paper 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 25 out of 100, across 18 categories.

Where grease resistant paper turns up

The 6 categories holding the most of it, out of 18. Each one links to the live ranking for that category, best graded first.

Best graded with grease resistant paper

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

Worst graded with grease resistant paper

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 coatings and finishes

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.
