    Frequently Asked Questions (FAQ)
    Q What is the difference between AS 5070/AS 5075H and AS 7751/AS 7777H in terms of retort resistance?
    AS 5070/AS 5075H offers retort resistance at 130℃ for 40 minutes, making it suitable for standard pharmaceutical flexible packaging. AS 7751/AS 7777H provides a higher retort resistance at 135℃ for 40 minutes, making it ideal for more demanding high-temperature sterilization applications.
    Q Are these adhesives compatible with aluminum-plastic multi-layer structures?
    Yes. Both AS 5070/AS 5075H and AS 7751/AS 7777H are specifically formulated to deliver high initial tack and high peel strength for aluminum (AL) and other multi-layer composite structures, ensuring reliable bonding and structural integrity.
    Q Which packaging types are compatible with AS 5070/AS 5075H?
    AS 5070/AS 5075H is suitable for a wide range of packaging types, including hot-fill products, stand-up spout pouches, zipper bags (PET/MPET structures), eight-side seal bags, special-shaped bags, and boiling-resistant products with thick PE film.
    Q What makes AS 7751/AS 7777H suitable for serrated or gear heat sealing?
    AS 7751/AS 7777H features a specially formulated soft adhesive layer that maintains structural integrity and appearance even under the mechanical stress of serrated or gear heat sealing processes, preventing delamination or surface defects in the final composite product.
    Q What type of laminating equipment is required for these adhesive products?
    Both AS 5070/AS 5075H and AS 7751/AS 7777H are designed for use with dry-type laminating equipment. They are not intended for flexo printing machines, solvent-free laminators, or coating machines, ensuring optimized performance in dry lamination processes.
    Q Do these adhesives prevent metallized layer transfer in composite packaging?
    Yes. AS 5070/AS 5075H is specifically noted for its ability to prevent metallized layer transfer when used with PET/regular MPET structures in zipper bags. This ensures an excellent appearance of the finished composite, maintaining the visual quality and barrier properties of the packaging.
