Frequently Asked Questions (FAQ)
Q
What is the difference between AS 7870/AS 7875H and AS 8260/AS 8275H in terms of retort performance?
AS 7870/AS 7875H offers a higher retort resistance of 135℃/40 min, making it ideal for applications requiring more extreme heat sterilization. AS 8260/AS 8275H is designed for 121℃/40 min retort conditions and additionally provides resistance to ethyl maltol additives commonly found in food products.
Q
Which adhesive products are compatible with solvent-free lamination equipment?
AF 2035/AF 2035H and AF 2036/AF 2036H are specifically formulated for use with solvent-free lamination equipment. The AS series (AS 7870/AS 7875H and AS 8260/AS 8275H) are designed for dry-type lamination processes.
Q
Are these adhesives suitable for stand-up spout pouches and special-shaped packaging bags?
Yes. All four product models — AS 7870/AS 7875H, AS 8260/AS 8275H, AF 2035/AF 2035H, and AF 2036/AF 2036H — are suitable for stand-up spout pouches, zipper bags, eight-side seal bags, special-shaped bags, and other flexible packaging formats including hot-fill applications.
Q
Does AF 2036/AF 2036H comply with food safety regulations?
Yes. AF 2036/AF 2036H meets the PPA (primary aromatic amine) content requirements specified in the Chinese national standard GB 4806.15‑2024, making it a compliant and safe choice for food flexible packaging applications involving aluminum inner layer structures.
Q
Which adhesive is recommended for PET/AL and MPET surface layer structures?
AF 2035/AF 2035H is specifically recommended for surface layer structures such as PET/AL and PET/MPET. It is compatible with various ink systems and ink coverage areas, and its high molecular weight formulation provides a long anti-blocking time on AL substrates for easier operation.
Q
Can AS 7870/AS 7875H be used for non-food industrial applications?
Yes. In addition to food flexible packaging, AS 7870/AS 7875H is also suitable for industrial applications such as building decoration films and home appliance films, thanks to its high initial tack, high peel strength, and soft adhesive layer that ensures excellent laminated product appearance.
