Frequently Asked Questions
Q
What is the difference between AS 3775/AS 3775H and AF 2021/AF 2021H adhesives?
AS 3775/AS 3775H is a dry-type and flexo lamination adhesive based on a polyether system, designed for high initial tack, fast curing, and retort-resistant plastic-plastic structures. AF 2021/AF 2021H is a solvent-free adhesive optimized for metallized and transparent flexible packaging, offering a low coefficient of friction and long tray life for high-speed production lines.
Q
What retort conditions do these adhesives support?
Both AS 3775/AS 3775H and AF 2021/AF 2021H provide excellent retort performance under 121℃ / 40 min conditions for plastic-plastic laminate structures, making them suitable for demanding food and daily chemical packaging applications.
Q
Is AS 3775/AS 3775H suitable for heavy-duty or thick film packaging?
Yes. AS 3775/AS 3775H is specifically formulated to bond thick LLDPE substrates with high slip agent content. It delivers strong peel strength and reliable adhesion even in heavy-duty flexible packaging applications.
Q
Can AF 2021/AF 2021H be used with thin LLDPE films?
Yes. AF 2021/AF 2021H is suitable for LLDPE film structures below 50 μm. Its fast-curing formulation ensures strong bonding without adversely affecting the coefficient of friction of the final laminate.
Q
What types of packaging equipment are compatible with these adhesives?
AS 3775/AS 3775H is compatible with Dry Type and Flexo lamination equipment. AF 2021/AF 2021H is designed for Solvent-Free lamination machines. Both products are intended for daily chemical flexible packaging production lines.
Q
Does AS 3775/AS 3775H produce white spots on PET/AL or MPET laminate structures?
No. AS 3775/AS 3775H features superior leveling and excellent surface wetting properties. It produces no white spots on PET/AL and MPET laminate structures, ensuring high transparency and an excellent finished appearance for premium flexible packaging.
