Frequently Asked Questions
Q
What is the difference between AS 3775/AS 3775H and AF 2021/AF 2021H in terms of suitable lamination equipment?
AS 3775/AS 3775H is designed for Dry Type and Flexo lamination equipment, while AF 2021/AF 2021H is formulated for Solvent-Free lamination machines. This distinction ensures each adhesive delivers optimal bonding performance on its intended equipment type.
Q
Can AS 3775/AS 3775H be used for retort packaging applications?
Yes. AS 3775/AS 3775H provides excellent 121℃/40 min retort performance for plastic-plastic structures, making it well-suited for demanding retort packaging that requires high heat resistance and reliable bond integrity.
Q
Is AF 2021/AF 2021H suitable for metallized flexible packaging?
Yes. AF 2021/AF 2021H is specifically suitable for metallized and transparent flexible packaging, including gas-filled packages. It meets high peel strength requirements for these structures while maintaining a low coefficient of friction.
Q
What are the curing conditions for AS 3775/AS 3775H?
AS 3775/AS 3775H features fast curing performance and is capable of curing at room temperature above 25℃. Its polyether system provides high initial tack and high peel strength, enabling efficient production cycles without requiring elevated curing temperatures.
Q
Does AF 2021/AF 2021H support high-speed lamination production?
Yes. AF 2021/AF 2021H offers a long adhesive tray life and fast curing properties, both of which are critical for supporting high-speed production lines. It is also compatible with LLDPE film structures below 50 μm without negatively impacting the film's coefficient of friction.
Q
Which adhesive is recommended for daily chemical flexible packaging with LLDPE substrates?
Both AS 3775/AS 3775H and AF 2021/AF 2021H are applicable for daily chemical flexible packaging. AS 3775/AS 3775H is particularly recommended for thick LLDPE substrates with high slip agent content and heavy-duty packaging, while AF 2021/AF 2021H is preferred when a low coefficient of friction and low extractables are required.
