They look like plastic bags but are made of materials like natural starch and vegetable oil derivatives. If placed in a glass of water at normal temperature, an EnviGreen bag dissolves in 24 hours. And when placed in a glass of boiling water, it dissolved in just 15 seconds! These bags take less than 180 days to biodegrade naturally once discarded. So users can throw them away without worrying about harming the environment. The bags are even edible and will cause no harm to animals if ingested. The manufacturing process for these bags is entirely different from that of plastic, cloth, or paper bags. The company uses 12 ingredients, including potato, tapioca, corn, natural starch, vegetable oil, banana, and flower oil.
