Safely warming up hot food-to-go is made simple with these Colpac Stagione microwavable paperboard food box lids. The paperboard construction and polypropylene lining means these lids can be safely used in microwaves. So when paired with the matching Colpac Stagione food boxes (FP457, FP458 and FP459), you can prepare and heat up food-to-go in the same packaging for a more efficient service. And venting holes also allow steam to safely escape without cooling down your food. Not only will this eliminate the risk of the lids bursting off in microwaves, but it'll also help to keep your food deliciously crispy for longer. Plus, the paperboard construction makes the lids fully recyclable after use too. So switching to them is a great way for you to do that little bit more for the environment.
