SOLUTION: At least one recess is formed in a primary sheet of water soluble or water dispersive substance. An agricultural chemical composition is disposed in the recess. Then, a secondary sheet of water soluble or water dispersive substance is placed on flanges, and the sheets are heat-sealed to form a continuous water-soluble or water-dispersive heat seal that is curved but has an angular intersection, thereby enclosing and packaging the contents. The contents is discharged within 10 minutes after the package and water undergo a melting reaction.
