Frequently Asked Questions (FAQ)
Q
What is the difference between AS 3775/AS 3775H and AF 2021/AF 2021H?
AS 3775/AS 3775H is a dry-type and flexo laminating adhesive based on a polyether system, designed for high initial tack and fast curing. AF 2021/AF 2021H is a solvent-free adhesive optimized for low coefficient of friction and low extractables, making it ideal for metallized and transparent flexible packaging.
Q
Are these adhesives suitable for retort packaging?
Yes. Both AS 3775/AS 3775H and AF 2021/AF 2021H deliver excellent retort resistance, passing the 121℃ / 40 min retort test for plastic-plastic laminate structures.
Q
Can AS 3775/AS 3775H be used with thick LLDPE films?
Yes. AS 3775/AS 3775H is specifically engineered to bond thick LLDPE substrates with high slip agent content, making it well-suited for heavy-duty flexible packaging applications.
Q
Does AF 2021/AF 2021H support high-speed lamination production?
Yes. AF 2021/AF 2021H features a long adhesive tray life and fast curing speed, both of which are critical properties for supporting continuous, high-speed lamination production lines.
Q
Will AF 2021/AF 2021H affect the slip performance of thin LLDPE films?
No. AF 2021/AF 2021H is formulated to be compatible with LLDPE film structures below 50 μm without affecting the coefficient of friction, ensuring the film's surface slip properties remain intact.
Q
What types of packaging are AS 3775/AS 3775H and AF 2021/AF 2021H primarily used for?
Both adhesives are primarily designed for daily chemical flexible packaging. AS 3775/AS 3775H also excels in PET/AL and MPET structures, while AF 2021/AF 2021H is particularly suited for metallized and gas-filled transparent packaging that demands high peel strength.
