Specifications
Butter paper temperature limit
Our silicone-coated butter paper is rated to 230 °C. We publish no heat rating for vegetable parchment or greaseproof uncoated, so keep those two out of the oven.

03 / Oven and OTG
Ovens and OTGs
An OTG is an oven, so the same limit applies: 230 °C for silicone-coated butter paper. Set the oven at or below 230 °C and the sheet stays inside its rating.
Brand ratings for baking paper differ. Wikipedia cites one brand at 216 °C. Read the rating for the paper in your hand, not a general figure.
04 / Air fryer
Air fryers
An air fryer blows hot air past a heating element. A loose sheet lifts in the airflow and touches the element.
Preheat the fryer empty, then add the sheet with food on top, flat and away from the element. Never run the fryer with a sheet and no food. Keep the setting at or below 230 °C.
05 / Microwave and steam
Microwaves and steaming
We have not tested our butter paper in a microwave or a steamer, so we make no claim for either.
For microwave or steam use, follow the guidance printed on the pack of a paper tested for the job.
06 / Which side
Which side of butter paper to use
Our specification sheet does not name a coated side for the silicone-coated type. Ask the sales desk before you rely on one face for release.
For the other two types, either face goes against food, since neither carries a coating.
