Case of 500. Unlike traditional soup cups/lids, our Vented Paper Soup, Hot or Cold Container Lids are made from a heavyweight durable paper board with a PE coating so you can have the confidence that the lid will not come off, until taken off. The venting on the lid will ensure that the lid wont blow off under steam from hot contents. Use for soups, stews, salads and more, these paper lids are perfect for fast food chains, restaurants, hotels and food trucks.
