Frequently Asked Questions
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, while AS 7751/AS 7777H provides a higher retort resistance at 135℃ for 40 minutes. Both are designed for aluminum-plastic multi-layer structures used in pharmaceutical flexible packaging.
Q
Are these adhesives compatible with dry-type lamination equipment?
Yes. Both AS 5070/AS 5075H and AS 7751/AS 7777H are compatible with dry-type lamination equipment. They are not designed for flexo printing, solvent-free, or coating machine processes.
Q
Which packaging types are suitable for AS 5070/AS 5075H?
AS 5070/AS 5075H is suitable for a wide range of packaging formats including hot-fill products, stand-up spout pouches, zipper bags, eight-side seal bags, and special-shaped bags. It is also ideal for boiling-resistant products using thick PE film.
Q
Does AS 5070/AS 5075H support MPET structures without metallized layer transfer?
Yes. AS 5070/AS 5075H features a soft adhesive layer that is specifically suitable for zipper bags with PET/regular MPET structures. It ensures no metallized layer transfer occurs, resulting in excellent appearance of the finished composite products.
Q
What makes AS 7751/AS 7777H suitable for serrated or gear heat sealing?
AS 7751/AS 7777H is specifically engineered to withstand the mechanical stress of serrated and gear heat sealing processes. Its high peel strength and soft adhesive layer maintain structural integrity and composite appearance even under these demanding sealing conditions.
Q
Are these adhesives suitable for pharmaceutical flexible packaging applications?
Yes. Both product models — AS 5070/AS 5075H and AS 7751/AS 7777H — are specifically listed under pharmaceutical flexible packaging applications. Their retort resistance, high peel strength, and compatibility with AL multi-layer structures make them well-suited for pharmaceutical packaging requirements.
