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-compatible adhesive based on a polyether system, optimized for high initial tack, fast curing, and retort performance in plastic-plastic structures. AF 2021/AF 2021H is a solvent-free adhesive designed for metallized and transparent flexible packaging, featuring a low coefficient of friction and long adhesive tray life for high-speed production lines.
Q
Are these adhesives suitable for retort packaging applications?
Yes. Both AS 3775/AS 3775H and AF 2021/AF 2021H provide excellent 121℃/40 min retort performance for plastic-plastic laminate structures, making them well suited for food and daily chemical flexible packaging that requires sterilization processes.
Q
Can AS 3775/AS 3775H be used with thick LLDPE films containing high slip agent content?
Yes. AS 3775/AS 3775H is specifically formulated to be compatible with thick LLDPE substrates that have a high slip agent content, making it an excellent choice for heavy-duty flexible packaging applications where adhesion to difficult film surfaces is required.
Q
Does AF 2021/AF 2021H affect the coefficient of friction of LLDPE films?
No. AF 2021/AF 2021H is designed to maintain the coefficient of friction of LLDPE film structures below 50 μm. Its fast-curing formulation ensures that film surface properties, including slip performance, are preserved after lamination.
Q
What types of packaging structures are compatible with AF 2021/AF 2021H?
AF 2021/AF 2021H is suitable for metallized and transparent flexible packaging structures, including gas-filled (MAP) packages. It meets high peel strength requirements for these structures and supports high-speed production thanks to its long adhesive tray life.
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 structures, ensuring high transparency, a soft adhesive layer, and excellent overall appearance for demanding flexible packaging applications.
