Natureflex is a natural, eco friendly film. It has a great Gas/Aroma Barrier but a low Oxygen + Moisture Barrier, so will not keep products fresh for an extended length of time. Cellophane is ideal for fast moving goods, products that don't require a long shelf life or non-food items. Can be used in a pie warmer or low oven heat. Natureflex is 100% biodegradable and compostable.
