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, while AS 7751/AS 7777H provides an enhanced retort performance at 135℃ for 40 minutes, making it suitable for more demanding sterilization conditions in pharmaceutical flexible packaging.
Q
Are these adhesives suitable for use with aluminum-plastic multi-layer structures?
Yes. Both AS 5070/AS 5075H and AS 7751/AS 7777H are specifically engineered with high initial tack and high peel strength to meet the bonding requirements of aluminum (AL) and other multi-layer composite structures commonly used in pharmaceutical flexible packaging.
Q
Which packaging types are compatible with these adhesive products?
Both product series are compatible with 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 and flexible packaging applications.
Q
Is AS 5070/AS 5075H suitable for zipper bag applications with MPET structures?
Yes. AS 5070/AS 5075H features a soft adhesive layer that is specifically suitable for zipper bags using PET and regular MPET structures. It ensures no metallized layer transfer occurs, resulting in excellent appearance and quality of the finished composite products.
Q
What type of heat sealing process is AS 7751/AS 7777H designed to support?
AS 7751/AS 7777H is specially formulated to withstand serrated and gear heat sealing processes, which are more demanding than standard flat heat sealing. This makes it an ideal choice for pharmaceutical packaging that requires this specific sealing method.
Q
Which lamination equipment types are compatible with these adhesives?
Both AS 5070/AS 5075H and AS 7751/AS 7777H are designed for use with dry-type lamination equipment. They are not applicable for flexo printing machines, solvent-free laminators, or coating machines, as indicated by the product specifications.
