Sealants

Consistent Seal Strength Across Broad Temperature Ranges

DuPont resins offer stronger, more consistent seal integrity throughout the package, helping eliminate weak spots that cause leaks.

DuPont packaging sealant resins deliver seal strength to support packaging seal integrity from production through consumption. We offer a wide variety of resin combinations and additives that perform consistently at broad seal temperature ranges and low sealing temperatures, with better seal-through contamination.

Our solutions also help manufacturers and converters reduce energy and resource usage. Low seal temperatures result in faster packaging line speeds, while our lightweight materials contribute to package weight reduction.

DuPont™ Surlyn® ionomer resins provide excellent hot tack and toughness and stiffness. DuPont™ Appeel® lidding sealant resins bond to a wide variety of substrates and peel predictably and cleanly when opening. DuPont™ Nucrel® acid copolymer resins bond directly to aluminum foil. And other resins offer softness, flexibility, and clarity. Regardless of different characteristics, DuPont sealant resins provide superior seal performance.
