Eco-Friendly 100% Compostable Sugar Cane Fiber Hinged Food Container - Medium Size 1-Compartment (200 Count Case) - Perfect for Meal Prep, Takeout & Sustainable Catering

We have gone through about 750 of these in the last year. We use at least two of these almost on a daily basis to bring lunch/dinner to work. Although the price went up about $10 after February 2014 (the fist 250-count box cost me $43.10 back then), they are still the best option I've found (and I've looked a lot!). They are an excellent choice for short-term (< 24H, we prepare our food the night before), relatively solid food storage.They need to be handled with care and you need a lunchbox with a hard lining to take them to work (we use this: Coleman 9-Can Soft Cooler With Hard Liner). They will also let some moisture out through the bottom just after you reheat your food in a microwave but a napkin or paper towel solves this issue. Of course you can find better containers, but these are the cheapest and more environmentally friendly option we've found so far that is good enough for our needs.If you want something that you can throw pretty much anywhere and is guaranteed not to leak, then try these: 16 Oz. Clear Deli Containers Newspring w/ Lids Combo Pack 240. We actually use the plastic deli containers for soups and some "runny" fruits like watermelon and pineapple.
