Reynolds Kitchens Pop-Up Parchment Paper Sheets are designed for convenience. The lay-flat parchment paper fits most standard baking pans and cookie sheets—no need to worry about rolling parchment or curling edges. You can easily grab a pre-cut parchment sheet right out of the box thanks to the pop-up dispensing system. Plus, Reynolds parchment paper sheets are non-stick—whether you're baking cookies or preparing a breakfast casserole, the food won't stick to the pan and makes for an easy clean-up. This parchment paper for baking is microwave-safe and oven-safe up to 425 degrees Fahrenheit.
