Abstract
A biodegradable (repulpable, compostable and/or water soluble) zipper is provided for attachment to a biodegradable flexible package. The biodegradable zipper is formed using a water-soluble polymer that can be combined with a repulpable and/or compostable material, such as a plant-based cellulose material. The biodegradable zipper enables the biodegradable package to be opened and closed by the consumer, so that the consumer has the option to determine, change or manipulate the contents of the biodegradable flexible package.
