Four Sizes Are Available Previous page Food wax coating's leakage resistance varies with food temp, storage time, and grease levels. Next page Previous page Next page Can these paper plates genuinely be composted? Joyborn paper plates, BPI-certified with authentication stamps, start decomposing within 30 to 45 days and completely break down by the 90th day in natural soil conditions. For best results, please use local commercial composting facilities. What sets these apart from regular paper plates? Joyborn paper plates are made from pressed sugarcane residue, a waste product, ensuring sustainability without the need to cut down any trees. Is it microwave-safe? They can be heated by microwave. But we recommend do not microwave oily foods, because high temperatures can damage the food wax coating on the plate, compromising its grease-resistant function. Can it hold foods with liquids/sauces? A food wax coating on paper plate that helps prevent liquid penetration to some extent. But, since it's not a plastic coating, the effectiveness in resisting leaks depends on factors like food temperature, duration of storage, and amount of grease. How should these paper plates be stored? To protect the performance and functionality of the food wax-coated paper plates, avoid excessive moisture, heat, or direct sunlight during storage. This can damage the food wax layer, affecting its water and grease resistance.
