The film used for our ecocapsules consists of a polyvinyl alcohol (PVA) polymer. By definition, a plastic is any synthetic, polymeric material that can be moulded into shape and set into a rigid or slightly elastic form. By this definition, PVA film can be regarded as a type of plastic. However, unlike other plastics, PVA film is fully water soluble and biodegradable by at least 55 different kinds of microbial organisms. It is also non-toxic to fish and even the most sensitive of aquatic microorganism, if released into the ocean or water streams. The PVA we use does thus does not pose any risk to the environment or its many beautiful creatures.
