Water soluble bag packaging system, film and method.

摘要

The present invention relates to a bag packaging system composed of a bag sealable to contain a liquid, in which the bag is composed of a continuous outer water soluble film (12) and an inner continuous protective film layer (14) that allows storage therein of a liquid that would chemically or physically react with the water soluble film but is prevented from doing so by the presence of the continuous protective film layer on the inner portion of the bag.
