Frequently Asked Questions
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, making it suitable for standard pharmaceutical flexible packaging applications. AS 7751/AS 7777H provides a higher retort performance at 135℃ for 40 minutes, making it the preferred choice for more demanding high-temperature processing requirements.
Q2
Are these adhesives compatible with aluminum-plastic multi-layer structures?
Yes. Both AS 5070/AS 5075H and AS 7751/AS 7777H are specifically designed for AL (aluminum) and other multi-layer structures. They provide high initial tack and high peel strength to ensure reliable bonding performance across complex laminated structures used in pharmaceutical flexible packaging.
Q3
Which adhesive 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 maintains structural integrity and composite appearance even under the mechanical stress of these specialized sealing methods.
Q4
What types of packaging formats are compatible with these adhesive products?
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 also supports boiling-resistant products with thick PE film, while both are ideal for pharmaceutical flexible packaging applications.
Q5
Will these adhesives cause metallized layer transfer in MPET structures?
No. AS 5070/AS 5075H is specifically noted for producing no metallized layer transfer when used with PET/regular MPET structures. Its soft adhesive layer ensures excellent appearance of the finished composite product, which is critical for high-quality pharmaceutical packaging aesthetics and integrity.
Q6
What lamination equipment types are compatible with these adhesive products?
Both AS 5070/AS 5075H and AS 7751/AS 7777H are designed for use with Dry Type lamination equipment. They are not formulated for Flexo, Solvent-Free, or Coating Machine applications, ensuring optimal performance when used within the specified dry lamination process.
