Nucrel® Acid Copolymer Resin

Ethylene Acrylic Acid Copolymer: Better Bonding to Metal

DuPont™ Nucrel® is used as a foil adhesive layer in juice and condiment packaging, as a heat sealant for tea bags and spice oil sachets, and as an adhesive in other aluminum applications.

DuPont™ Nucrel® ethylene acrylic acid and methacrylic acid copolymer resins provide excellent adhesion to aluminum and other polar substrates, as well as to nylon and paper. As a seal layer in laminated and coextruded structures, Nucrel® acid copolymer resin resists delamination and seal failure, even in aggressive chemical environments.

Nucrel® benefits include excellent hot tack strength, toughness, and low-temperature seal initiation. It extends product shelf life and provides excellent seal-through contamination. It also allows for high-speed packaging and results in fewer package failures, which helps reduce waste. Other applications that use Nucrel® include cable shielding and aluminum building panels.

DuPont is the world’s largest producer of ethylene acrylic acid and methacrylic acid copolymer resins. We draw from our broad product portfolio and technical expertise to help manufacturers and converters develop new application-specific packaging solutions.
