This clear PLA lid fits our line of 9 x 7″ fiber containers. PLA is a common bio-polymer used in food packaging, and is 100% certified compostable. The clear transparency makes this lid great for grab n’ go foods, or any application that requires the food to show beautifully through the top, catching the eye of a hungry customer. It should be noted that PLA is not meant to be placed under high heat. We recommend cold and warm foods only. Meals just out of the oven or frying pan may cause warping.
