    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 ideal for standard pharmaceutical flexible packaging with aluminum-plastic structures. AS 7751/AS 7777H provides a higher retort resistance at 135℃ for 40 minutes, suitable for more demanding sterilization conditions and applications requiring serrated or gear heat sealing.
    Q Are these adhesives compatible with solvent-free or flexo lamination equipment?
    Both AS 5070/AS 5075H and AS 7751/AS 7777H are designed for use with dry-type lamination equipment only. They are not specified for flexo, solvent-free, or coating machine applications based on their current product configuration.
    Q What types of packaging formats are suitable for these pharmaceutical adhesives?
    Both product models support a wide range of packaging formats including hot-fill products, stand-up spout pouches, zipper bags, eight-side seal bags, and special-shaped bags. AS 5070/AS 5075H is additionally suitable for boiling-resistant products using thick PE film with high peel strength requirements.
    Q Will these adhesives cause metallized layer transfer when used with MPET structures?
    No. AS 5070/AS 5075H features a soft adhesive layer specifically engineered to prevent metallized layer transfer when used with PET or regular MPET structures. This ensures excellent appearance quality in the finished composite packaging.
    Q Which adhesive model is recommended for serrated or gear heat sealing processes?
    AS 7751/AS 7777H is specifically formulated to be resistant to serrated and gear heat sealing processes. Its soft adhesive layer and high peel strength make it well-suited for packaging lines that utilize these specialized heat sealing methods.
    Q What multi-layer structures are these adhesives designed to support?
    Both AS 5070/AS 5075H and AS 7751/AS 7777H are designed to support aluminum (AL) and other complex multi-layer structures commonly used in pharmaceutical flexible packaging. They provide high initial tack and high peel strength to ensure reliable bonding performance across these demanding laminate constructions.
