I first heard about these bagasse containers in a comment thread discussing alternatives to foam boxes. Curious, I looked deeper and ended up reading about https://mcdonaldpaper.com/safepro-bc883pf-8x8x3-inch-3-compartment-pfas-free-bagasse-hinged-take-out-container-200-cs/. The three compartments immediately appealed to me. I tried one with rice, vegetables, and sauce, and nothing mixed together. The lid closed securely, and the container felt sturdy even with hot food inside.
