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 is rated for a higher temperature of 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 specifically designed for use with dry-type lamination equipment. They are not intended for flexo printing, solvent-free, or coating machine processes.
Q
Which packaging formats are supported by these pharmaceutical adhesives?
Both adhesive models support a wide range of packaging formats, including stand-up spout pouches, zipper bags, eight-side seal bags, special-shaped bags, and hot-fill product packaging. This makes them highly versatile for modern pharmaceutical flexible packaging lines.
Q
Does AS 5070/AS 5075H prevent metallized layer transfer in MPET structures?
Yes. AS 5070/AS 5075H features a soft adhesive layer that is specifically formulated to prevent metallized layer transfer when used with PET/regular MPET structures. This ensures excellent visual appearance and structural integrity of the finished composite packaging.
Q
Is AS 7751/AS 7777H suitable for serrated or gear heat sealing processes?
Yes. AS 7751/AS 7777H is specifically engineered to withstand serrated and gear heat sealing processes. Its soft adhesive layer and high peel strength ensure reliable bond performance even under these demanding sealing conditions.
Q
Can AS 5070/AS 5075H be used for boiling-resistant packaging with thick PE film?
Yes. AS 5070/AS 5075H is suitable for boiling-resistant applications that use thick PE film and require high peel strength. Its formulation ensures the adhesive bond remains stable and intact under boiling conditions, making it ideal for demanding food and pharmaceutical packaging.
