Appeel® 22D843 lidding sealant resin from DuPont Packaging & Industrial Polymers is pellet-blended with a polypropylene sealant resin solution to provide converters with an easy and effective way to make peelable lids for retortable polypropylene (PP) packages.

After blending, Appeel 22D843 is then processed to make a lidding
structure or sealant layer in conventional extrusion or coextrusion
equipment designed for polyolefin resins. Allows converters to tailor peel force
and achieve consistent sealing and peeling performance with a
preformulated masterbatch. The resin is typically blended with PP at
addition rates of 20 to 40% by weight. The proportion of Appeel® in the
blend determines peel strength. Lower addition rates result in higher
peel force and vice versa.
