Abstract

A repulpable zipper is provided for attachment to a repulpable flexible package. The repulpable zipper is formed using a water-soluble polymer combined with a repulpable material, such as a plant-based cellulose material. The repulpable zipper enables the repulpable 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 repulpable flexible package.
