Appeel® 22D843

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.
