DuPont™ Appeel® 22D843 Ethylene Acrylate

DuPont™ Appeel® 22D843 is a polypropylene modified ethylene acrylate resin designed to function as a masterbatch to achieve peelability in polypropylene based sealant layers. It provides peelable seals over a broad temperature range. The peel layers will sustain sterilization conditions of 121°C for 20 minutes through 134°C for 6 minutes depending on the base of the PP seal materials. When blending for this type of application, 22D843 should be evaluated as a modifier for HoPP or CoPP by addition rates between 20% to 40% by weight. Blends with CoPP will usually provide better results. Appeel® 22D843 is available in pellet form for use in conventional extrusion and coextrusion equipment designed to process polyethylene resins. Appeel® 22D843 Lidding Sealant Resin complies with Food and Drug Administration Regulation 21 CFR 177.1340 - - Ethylene-methyl acrylate copolymer resins, subject to the limitations and requirements therein. Appeel® 22D843 Lidding Sealant Resin may be used in non-cooking applications under conditions corresponding to Conditions of Use C (Hot filled or Pasteurized above 150F, includes microwave reheating) through G (frozen storage, no thermal treatment in the container) (21 CFR 176.170, Table 2, subject to the finished food-contact article meeting the extractive limitations under the intended conditions of use, as shown in paragraph 21 CFR 177.1340 paragraph (b). Appeel® 22D843 Lidding Sealant Resin may also be used for packaging all food types in a cooking application at a maximum thickness of 3.5 mils in pouches under retort conditions only, corresponding to Condition of Use A (21 CFR 176.170, Table 2), subject to the finished food-contact article meeting the extractive limitations under the intended conditions of use, as shown in paragraph 21 CFR 177.1340 paragraph (b).
