Brand information
NUCREL™ resins are branched copolymers of ethylene and methacrylic or acrylic acids. Acid side chain branches bring unique functionality to these highly polar resins, while long chain branches make these resins easy to use in producing blown and cast films, as well as extrusion coatings and laminations.
NUCREL™ for packaging applications
NUCREL™ provides excellent adhesion to metal with low-temperature seal-through-contamination properties ideal for packaging products from condiments to juices and aseptic milk to pharmaceuticals and personal care products.
NUCREL™ ethylene acid copolymer resin provides an outstanding, chemically-resistant metal bond, making it a reliable, cost-effective foil adhesive for a range of applications. NUCREL™ bonds to the oxide layer on the aluminum and provides strong bonds that are resistant to attack by mild to moderate acids and bases.
Besides foil, NUCREL™ can adhere to paper in extrusion coating, nylon in coextrusion, and can be extruded or injection molded at slightly lower processing temperatures than polyethylene (PE).
NUCREL™ is also an excellent heat sealant, with hot tack strength and seal through contamination properties that allow for reliable heat seals at high packaging machine speeds.
Other performance properties include toughness, light weight and durability in aggressive chemical (e.g., acetic acid) environments.
