Round paper containers with paper lids are now extensively used as takeout containers for food delivery by consumers seeking an environmentally friendly option.
These containers are composed of food-grade paperboard that has been poly-coated on the inside and come with a matching paper lid. The coating protects the container from liquid absorption and makes it reasonably leak-proof.
These 500 ml disposable plastic containers are often used to carry gravies, sauces, salads, and other foods.
It is not suggested that these containers be microwaved.
