DuPont Nucrel® AN4228C is a terpolymer designed for extrusion coating processes, with 4.0% methacrylic acid content. Processable on standard polyethylene equipment, it provides high-adhesion bonding to PET, metal foil and other substrates without chemical primers, serving as an efficient adhesive layer material in composite packaging.
Primerless adhesion, enabling strong bonding to PET, metal foil, EVOH and nylon without additional chemical treatment, simplifying processes and reducing costs.
Excellent equipment compatibility, suitable for standard polyethylene extrusion and co-extrusion equipment, enabling rapid production without line modifications.
High processing stability, with melt index and density parameters optimized for extrusion coating, ensuring uniform coating and consistent product quality.
Food contact safety, compliant with food packaging material standards, directly applicable to food, pharmaceutical and other sensitive packaging applications.
Strong interlayer adhesion, enhancing impact resistance and weatherability of multi-layer packaging structures and reducing delamination risk.
Food and non-food pouch packaging, acting as the adhesive layer for PET/LDPE or PET/metal foil to improve seal integrity and barrier properties.
Liquid paperboard packaging, serving as the adhesive layer between PET and paperboard to enhance liquid resistance and structural strength.
Medical and pharmaceutical packaging, used to produce high-barrier composite films for maintaining drug stability during shelf life.
High-barrier composite film production, acting as the tie layer between EVOH and polyolefins to optimize oxygen and moisture barrier performance.
Electronic device moisture-proof packaging, used to manufacture high-seal composite materials for protecting sensitive components from moisture damage.
