No. Our bags are made from a biodegradable woven mesh called Soilon. Soilon is derived from corn starch and can be composted completely. Soilon is a safe, non-toxic, environment-friendly material, perfect for filtering tea and herbal infusions.
Soilon is made of poly lactic acid (PLA) polymer resin, made by lactic fermentation of glucose (derived from corn starch) by an enzyme and polymerization.
Unlike traditional petroleum-based plastics, PLA is a plastic substitute made from fermented corn starch.
