12 oz paper bowls are made from unbleached paper, an annually renewable resource. These bowls have a poly-coated lining, not petroleum, making them 100% recyclable. The leak-proof design makes them perfect for soups, stews, hot sides, steamed veggies, ice cream, yogurt, and sorbet. Great for delis, hotels, and restaurants serving takeout, to-go, or delivery, these bowls work for hot or cold foods and show a commitment to environmental responsibility!
