Cover up cold beverages in a sustainable way with our Basic Nature Round Clear PLA Plastic Drinking Cup Lids. Crafted from PLA plastic, a bioplastic derived from cornstarch, these biodegradable lids are commercially compostable and a great eco-friendly alternative to foam lids. With a durable design, these drinking cup lids prevent accidental spills when serving beverages at your diner, bakery, or cafeteria. With a built-in straw slot, these crack-resistant lids allow you to easily insert a straw into cups to comfortably sip on drinks. These cold cup lids are specially designed to form a secure fit on our 20-ounce PLA cups (SKU: RWP0165C). Featuring a clear finish, these clear plastic lids effortlessly showcase the colors of your lemonade, iced coffee, juice, and other cold refreshments. Measuring 4 inches in diameter and 0.3 inches in height, these flat lids are sold in a 1,000 count box. This item will only degrade outside of the traditional solid waste stream. PLA drinking cups are available and sold separately. NOTE: Store and use under 105F. Avoid prolonged exposure to direct sunlight. Suitable for cold food items only.
