PACKAGE FOR CHEMICALS Russian patent published in 1999 - IPC

FIELD: materials handling facilities; packing of measured amounts of chemicals, for instance, pesticides. SUBSTANCE: package is made in form of bag whose inner surface is formed by inner layer of multiple-layer water soluble polymeric film, and outer surface is formed by outer layer of multiple-layer film which is non-water-soluble.
