Vinylidene chloride is used in the production of polyvinylidene chloride (PVDC) copolymers. PVDC was developed by Dow Chemical Company, and was at one point used in the production of the popular food wrap product, Saran Wrap. PVDC has characteristics ideal for food packaging because it has low permeabiltiy to water vapor and gasses. While use of PVDC in Saran Wrap was later phased out due to cost and environmental concerns, other copolymers of vinylidene chloride are still commonly used in food packaging, including box overwrap, vertical form fill seal, horizontal form fill seal, and pre-made bags. Vinylidene chloride is also extensively used in a variety of other packing materials, as flame retardant coating for fiber and carpet backing and in piping, coating for steel pipes, and adhesive applications. Other common consumer products that may contain vinylidene chloride include cleaning cloths, filters, screens, tape, shower curtains, garden furniture, artificial turf, doll hair, stuffed animals, fabrics, fishnet, and shoe insoles.
Manufacturers, distributors and retailers are required to provide Prop 65 warnings to workers and consumers who are exposed to vinylidene chloride. Companies have one year from the listing date to comply with Prop 65. Companies that have not reformulated their products to remove vinylidene chloride, or that fail to provide a Proposition 65 warning on products containing it, by December 29, 2018 are at risk of receiving a “Notice of Violation” from private enforcers seeking to gain thousands of dollars in penalties and attorneys’ fees. A Notice of Violation typically precedes a lawsuit for violation of Proposition 65.
The listing of vinylidene chloride as a chemical known to cause cancer by OEHHA is a reminder that not only product contents, but also packaging materials, are included within Prop 65 compliance requirements. As we previously reported, since December 2014, products sold in California that contain diisononyl phthalate (DINP) have required a Proposition 65 warning. DINP is found is many soft plastic and vinyl products, and purported violations have been found in seemingly innocuous packaging, such as gift bags for cosmetic products.
