Applied in multilayer composite bonding for pharmaceutical packaging. Bonds plastic films such as PET, PA, PE, PP, metallized polypropylene films (VMCPP), metallized polyester films (VMPET), and aluminum foil. The adhesive ensures high safety, strong barrier properties (moisture/oxygen resistance), durability, and specific functionalities. It isolates pharmaceuticals from external environments, prevents deterioration, oxidation, and contamination, and significantly reduces risks of damage and leakage during transportation and storage. Suitable for pharmaceutical packaging applications, such as aluminum foil bags and blister packs, meeting the pharmaceutical industry’s demands for diversified, highperformance, and chemicalresistant materials.
