This product is a water-based heat seal coating recommended for assessment in specific visual carded packaging applications. This product harnesses advanced polyurethane technology to create robust, fiber-tearing bonds with recycled polyester (RPET) and standard rigid vinyl (PVC) blisters. This product is designed for in-line wet trapping applications but can also be applied offline over blister-grade offset and flexographic inks.

    Applications & Uses

    Recommended Uses

    LOCTITE LIOFOL HS B7707AR is suggested for evaluation as a heat seal coating for blister packaging applications providing a viable alternative to solventbased systems, resulting in zero solvent VOC emissions and a “green” technology. LOCTITE LIOFOL HS B7707AR was specifically formulated for use with RPET and PVC blisters. This system may also prove functional for PETG, cold formed, and narrow flanged blisters. However, proper testing and evaluation of seals and aged performance is required to ensure functionality.

    Applications Conditions
    • Application : In-line offset
    • Reducer : Ready-to-Use; Water, if required
    • Drying : 95-105°F (35-41°C) substrate temp with air flow
    • Coating Weight : 0.40-0.50 dry lbs/1,000 sq. ft.



    In laminations, exact heat sealing conditions will vary according to the type and gage of plastic film or base stock, depending on whether sealing is direct (through the film) or indirect (through paper).

    1Bond interface temperature is the temperature required at the sealing area between the film and the base stock. These seal conditions are only suggested as a starting point. All bonds should be thoroughly tested.
