Material Notes:
9 wt% Acrylic Acid.Nucrel® 3990 is an ethylene-acrylic acid copolymer resin available for use in conventional extrusion coating, coextrusion coating, and extrusion laminating equipment designed to process polyethylene resins.Features/Benefits: Excellent adhesion to unprimed foil, paper, and metallized film. Provides substrate protection for improved structure reliability and barrier integrity. Can be extruded at low temperatures for insurance against off-tastes, off-odors, and taste/odor complaints. Low seal initiation temperature allows higher speed packaging. Good hot tack, sealability through contamination, and heat seal strength provide strong, reliable heat seals.Typical Applications: Foil-containing shampoo, toothpaste, towelette, condiment and miscellaneous nonfood pouches and sachets. Snack structures. Other foil, metallized film, or paper coatings as a heat seal or tie layer.Information provided by DuPont Packaging Polymers.
