The present invention is directed to water-soluble film comprising: -Component % By Weight -Polyvinyl Alcohol 40-75 -Polyvinyl Pyrrolidone 7.5-43 - Ethoxylated Alkyphenol 7-20 -Polyhydric Alcohol 7-20 - The cold water-soluble packaging films formed from the compositions of this invention are useful for packaging of agricultural chemicals which are in granule or dust form. By containing such water dispersable granule or dust agricultural chemicals in water-soluble bag films of this invention, one is able to avoid the problem of dust which may be irritating and/or toxic to the user. Specific examples of agricultural chemicals which are usually packaged in pre-measured portions in the water-soluble films of the present invention are insecticides, herbicides, nematocides, fungicides, plant growth regulants and herbicidal antidotes. The water-soluble films of the present invention may also be useful in containing such items as laundry detergents, bleaches and caustic products; other uses would involve the containment of activated charcoal, pigments, dyes, foodstuffs and food additives. |
