EarthChoice® Polylactic Acid (PLA) Coated Paper is used for Pactiv's compostable hot cups and soup cups. While PLA is used for cold applications, when the PLA film is applied to paper such as our hot cups and soup cups, the PLA film takes on the properties of the paper and therefore does not melt or deform making these cups a great choice for both hot and cold applications. Additionally, these cups are conveniently color-coded for sizing. Pactiv's PLA Lined/Coated Paper Cups are made from 100% annually renewable resources and are ASTM D 6400 certified and compostable in commercial facilities only, which may not exist in all areas. Not suitable for backyard composting.
