Our sandwich boxes are flat-packed and very quick and easy to construct. They are made of card and lined with PLA, a plant-based plastic, and not a petroleum-based plastic. The clear window is also PLA. PLA provides a barrier to oils and sauces and avoids leakage. As food contamination is not a problem, the waste container can be sent to a landfill (to eventually breakdown into plant matter) or sent to a commercial composting centre (for conversion into compost).
