ABSTRACT:
A method of forming a useful molded part or film of polyvinyl alcohol. The polyvinyl alcohol, together with a plasticizer is injection or blow molded to form the useful molded part or melt processed (blown or cast extrusion) to form the film wherein upon forming the useful molded part or film, the plasticizer is substantially removed to create the useful molded part or film which is selectively hot water soluble and which is resistant to the affects of moisture below the solubility temperature.
