A multiple layered bag comprising such materials that one surface of the bag degrades when it comes in contact with water, for example polyvinyl alcohol, while the other surface is water resistant, such that the bag can be used to collect moist materials, for example pet excrement, without exposing the bag handler to those moist materials, yet when the everted bag is subjected to an aqueous environment, with the liquid degradable surface exposed to the aqueous environment, all the components of the bag degrade. The bag degrades such that the remaining components of the bag and the contents thereof are easily flushed down the toilet.
