Vinylidene chloride is a versatile monomer used primarily for making vinylidene chloride copolymers. These copolymers are mostly used in food packaging to provide a good barrier to mass transport. Most applications rely on the low permeation of oxygen, carbon dioxide, and water vapor. However, the polymers have also been shown to have good barrier to flavors and aromas. These copolymers are available in three formats. First, resin for extrusion into film or sheet represents the largest segment. Typically, coextrusion is used because only a small amount of vinylidene chloride is necessary for the barrier and other polymers can provide the strength. Second, resin is used for solution applications. A thin layer is coated onto a substrate. Third, latex is used for coating. The coatings from solution or latex dry clear. Vinylidene chloride homopolymer does not have commercial application because its melting temperature is too high to extrude without degradation, and it does not dissolve in a suitable solvent for coating.
