Abstract: A three part laminated material for use in making blister packages and a method of making such a material. The material is comprised of a central core layer of fluoro-polymer based sheet material to each side of which a separate polymer film is adhesively attached. These separate films may be symmetrical or asymmetrical as regards each other. In the preferred embodiment, each of the polymer films is polyvinyl chloride, although a variety of chemically different films may be used. The disclosed material provides a high moisture barrier, reduced package curl, a stable inter-laminar structure and outer surfaces which lend themselves well to bonding with other materials as well as to printing and coating.
