Pharmaceutical Flexible Packaging Adhesives from China Suppliers - High-Performance Factory Solutions for Sterilization and Safety

,

Discover top-tier pharmaceutical flexible packaging adhesives from leading China suppliers and factories. Our specially formulated adhesives are pharmaceutical-grade, designed for high-performance bonding in diverse packaging scenarios. Addressing core requirements such as high-temperature sterilization, superior bonding strength, sealing, barrier properties, and compliance with safety standards, our solutions employ a dry lamination process that integrates seamlessly with pharmaceutical flexible packaging production equipment. This ensures reliable and stable bonding for aluminum-plastic multi-layer structure packaging. We offer two tailored products: AS 5070 and AS 5075H, ideal for thick PE boiling-resistant products and various bag types, while AS 7751 and AS 7777H are engineered for high-temperature retort processes and serrated/gear heat sealing. Our adhesives provide an optimal balance of bonding reliability, operational efficiency, and pharmaceutical-grade safety compliance, empowering enterprises to enhance production efficiency, maintain excellent sealing and barrier performance, and ensure high-temperature resistance and aesthetic quality in their pharmaceutical flexible packaging. Meet stringent sterility, safety, and compliance requirements while fully protecting drug quality and medication safety with our premium adhesive solutions.

    Frequently Asked Questions (FAQ)
    Q1 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, while AS 7751/AS 7777H provides a higher retort resistance at 135℃ for 40 minutes. Both are designed for aluminum-plastic structures used in pharmaceutical flexible packaging.
    Q2 Are these adhesives compatible with dry-type laminating equipment?
    Yes. Both AS 5070/AS 5075H and AS 7751/AS 7777H are suitable for use with dry-type laminating equipment. They are not designed for flexo, solvent-free, or coating machine processes.
    Q3 Which packaging types are supported by these adhesive products?
    Both products 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 — making them highly versatile for pharmaceutical flexible packaging applications.
    Q4 Is AS 5070/AS 5075H suitable for zipper bags with MPET structures?
    Yes. AS 5070/AS 5075H features a soft adhesive layer that is specifically suitable for zipper bags with PET/regular MPET structures. It prevents metallized layer transfer and ensures an excellent appearance for finished composite products.
    Q5 Can AS 7751/AS 7777H be used with serrated or gear heat sealing equipment?
    Yes. AS 7751/AS 7777H is specifically formulated to withstand serrated and gear heat sealing processes, making it a reliable choice for pharmaceutical packaging lines that utilize these specialized sealing methods.
    Q6 Does AS 5070/AS 5075H support boiling-resistant applications with thick PE film?
    Yes. AS 5070/AS 5075H is suitable for boiling-resistant products that use thick PE film and require high peel strength. This makes it an ideal adhesive solution for demanding pharmaceutical packaging environments.
