Eco-Products EP-BL6LID WorldView 6-8 oz. compostable plastic coupe bowl lids are an ideal alternative to petroleum-based plastic. It's made of PLA, a plant-based plastic that's formed with renewable resources to minimize environmental impact upon disposal. It's created specifically for use with cold foods, making it great for housing or displaying leafy-green salads or cold pastas. The lid also snaps closed with a tight seal to prevent accidental spills.
