THREE PART HIGH MOISTURE BARRIER FOR PACKAGES |
摘要 |
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 cor e 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 i s polyvinyl chloride, although a variety of chemically different films may be sued. 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.
