I like to use meal prep containers that I get off Amazon. Recently, I switched to glass containers, so that I can heat up my lunches in the microwave and not worry about chemicals leaching into my food. Glass containers are more of a pain to store in my kitchen, but I'm willing to pay that price to deal with them. I have both single chamber and dual chamber 36oz containers. Just search "Meal prep glass containers" on Amazon and you will find a variety of options.
