When using IF YOU CARE Unbleached Baking Paper no greasing is necessary, saving you both time and calories. The paper has been coated with silicone & a non-organic natural product & on both sides. Silicone is derived from Silicon, a natural element found in sand, quartz, and rock. After oxygen, it is the most abundant element on Earth. Silicone is non-toxic when incinerated and landfill safe. It is both the most effective and the most environmentally friendly non-stick surface coating. Unfortunately, many parchment papers are coated with Quilon, a chemical containing Chromium & a heavy metal & which when incinerated becomes toxic and leaves trace elements behind. The reason most parchment paper is Quilon-coated is the cost, which is substantially lower than silicone. Since it can be reused several times, silicone-coated paper is also cost effective and has traditionally been the choice of professionals. In addition to these benefits, this paper is 100% unbleached so no chlorine is dumped into our waterways during production. When you are all done using it this paper is also completely compostable. Packaged in a 100% recycled, recyclable and biodegradable paperboard container printed with vegetable-based inks.
