About this project Extra thick but inexpensive, our parchment paper is 45gsm. Compared to 35gsm paper, our paper is stronger, more durable and less brittle, so you can easily lift the food on the baking sheet without breaking by simply lifting the parchment paper. Also, it is more cost-effective than other products. Including 5000mm long, 30cm wide / 11.81", it fits perfectly in a standard half sheet pan, and the sheets fit neatly in a convenient box. Using pre-cut paper allows you to just take out a piece of parchment paper and spread it on the baking sheet, which makes your baking process convenient and effectively saves you the hassle of measuring and cutting from a curled parchment roll. Natural, Unbleached and Non-toxic Materials: Made from natural wood pulp, completely non-fluorescent, chlorine-free, waterproof, food-grade, unbleached, non-toxic and BPA-free. Oven and microwave safe to 450°F, so it won't curl when baking on high heat. Non-stick: Having it on a baking sheet means you don't have to grease and the cookies will slide off right away (and are easier to clean afterward). It also prevents baked goods and sweets from sticking or frosting by placing a piece of parchment paper between each layer of the container or box. At the same time, it cleans up easily and avoids sticky dough sticking to hard-to-remove baking sheets. MULTIPLE USAGE: It is very frequent and easy to use in the kitchen and everyday when you want to bake cookies, cakes, macaroons, bread, pizza, brioche or serve chips, grilled chicken wings, burgers or even wrap sandwiches items, croissants or hot dogs, gifts, etc.
