These deli containers are our answer to the quart, pint, cup and universal lid combos that grocery stores and delis say they just can't live without. We're proud of these and think that despite the fact that our corn polymer blend is not transparent (like others) they do hold up to boiling water and can go from the freezer to the microwave – so they are the answer to not just soups and prepared food, but bulk food sales and deli items too! Each size uses the same lid and it's a snug, well-engineered solution that takes bioplastic food containers to new heights. We're very pleased to be able to offer these new containers but order now because they are starting to fly out the door!
