FCN No. 956

Return to Listing
Food Contact Substance:  Copolymers of caprolactone prepared by the polymerization of caprolactone with up to 2.25 percent 1,4-butanediol (CAS Reg. No. 31831-53-5 or CAS Reg. No. 24980-41-4).
Notifier:  Sealed Air Corporation
Manufacturer:  Sealed Air Corporation
Intended Use:  The food-contact substance is intended for use at levels up to 10.3 percent in typical vinylidene chloride copolymers (PVdC) that in turn are used in the construction of multilayer materials used for packaging food.
Effective Date:  06/19/2010
Limitations/Specifications:  The polyvinylidene chloride layer will be no more than 5 microns thick and will be separated from food by at least 29 microns of polymer. Such construction may be used in contact with all food types under Conditions of Use E through G, as described in Tables 1 and 2.
