ABSTRACT:
A composite film bag 1 for packaging comprises a composite film of a water-insoluble film 2 and a water-soluble polyvinyl alcohol film 3 which are adhered to one another to such an extent that the former film 2 can easily be peeled off from the latter film 3 and which are formed into a bag so that the water-insoluble film 2 serves as an outer layer of the bag and the water-soluble polyvinyl alcohol film 3 serves as an internal layer thereof. A powdery or liquid agricultural chemical agent 6 is packed in the composite film bag 1 and the opening of the bag is sealed. Upon practical use, the outer water-insoluble film 2 is peeled off to expose the internal film 3 and the internal film 3 as such, while containing the agricultural chemical agent 6, is introduced into water. Thus, the internal film is dissolved in water and in turn the content 6 thereof is released and accordingly dissolved in water. The composite film bag 1 is not broken at all even when it is exposed to a low temperature condition.
