The 6" White Biorenewable Hinged Container, sold 400 per case, is the environmentally-conscious way to serve guests their food to-go. This container is the perfect size to package large sandwiches quickly and easily in this one-piece container. The base has ridges to help keep food from sliding around, and the lid folds down by its attached-hinge to securely close everything. The material is certified by the Biodegradable Products Institute as completely compostable, and it's made from 100% renewable resources. Even though this is a natural product, it's still durable and non-absorbent, as well as microwave-safe for reheating hot foods.
