Then the biaxially oriented polyester film as the outer layer of the bag containing the agricultural chemical agent was manually peeled off to thus expose the polyvinyl alcohol film as the internal layer thereof and the bag was introduced into a tank containing 10 l of water to dissolve the polyvinyl alcohol layer and hence the content agricultural chemical agent of the bag. The resulting laminate film was formed into a composite film bag for packaging by repeating the same procedures used in Example 1. The composite film bag of claim 1 wherein the adhesive is acrylic co-polymer polymerized from a mixture of methyl methacrylate and butyl methacrylate and subsequently crosslinked by prepolymers of melamine resin. These sample bags were put in a carton of corrugated board and subjected to a dropping test similar to that carried out in Example 1. Vision is our core strength, with resources devoted to pioneering new product types to solve tomorrow’s most challenging issues today. In the composite film bag for packaging according to the present invention detailed above, the internal polyvinyl alcohol film is protected from any breakage due to the presence of the outer film having high resistance to low temperature conditions even if the bag more specifically the internal film is exposed to a temperature higher than the brittle point thereof in the course of the distribution thereof.

Thus, agricultural chemicals can be handled with high safety and hygiene. The bilayer film of this type can be prepared by forming, in advance, one of the films required and then applying a solution of a polymer as a material for the other film onto the surface of the film previously formed.
