Our plant fiber based trays are now made from unbleached wheatstraw fiber, an annually renewable resource. We offer three sizes: a 6.5" x 5" boat tray, a three compartment tray, and a five compartment tray. Though these compostable trays are soak proof, hot items will cause the plates to "perspire" and some condensation will form at the bottom so please be aware.
These compostable sushi trays are made from Natureworks Ingeo(tm) PLA. This PLA is derived from plants grown in the USA. These PLA sushi trays are designed for cold and lukewarm foods below 110 degrees Fahrenheit.
