What is PLA?
PLA is an acronym that stands for polylactic acid. PLA is a resin or bio-resin typically made from corn starch or other plant-based starches. PLA is used to make clear compostable containers and PLA lining is used in paper or fiber cups and containers as an impermeable liner. PLA and PLA-lined products are commercially compostable. Certified compostable PLA products are tested to meet ASTM standards. PLA made from corn is renewable, because corn can be harvested and re-grown annually.
PLA products such as clamshells and deli containers are clear, and so they can display and show off their contents well. PLA containers are designed for cold foods, and should not be used with foods over 105F.
Compostable PLA containers are intended for commercial composting which is not available in all areas, and different states have different requirements for composting. Please check locally to ensure you have access to commercial composting before purchasing compostable products.
