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 polyether-based adhesive designed for high initial tack and fast curing, making it ideal for heavy-duty packaging and thick LLDPE substrates. AF 2021/AF 2021H is a solvent-free adhesive optimized for metallized and transparent flexible packaging with a low coefficient of friction and low extractables.
Q
What retort performance do these adhesives offer?
Both AS 3775/AS 3775H and AF 2021/AF 2021H deliver excellent retort performance at 121℃ for 40 minutes for plastic-plastic laminate structures, making them suitable for demanding food and daily chemical packaging applications.
Q
Is AS 3775/AS 3775H suitable for PET/AL and MPET laminate structures?
Yes. AS 3775/AS 3775H features superior leveling and excellent surface wetting, which ensures no white spots appear on PET/AL and MPET structures. The result is a high-transparency, soft adhesive layer with excellent overall appearance.
Q
Can AF 2021/AF 2021H be used for high-speed production lines?
Yes. AF 2021/AF 2021H features a long adhesive tray life and fast curing properties, both of which are specifically designed to support high-speed lamination production without compromising bond quality or the coefficient of friction of the film.
Q
What film thickness is AF 2021/AF 2021H compatible with?
AF 2021/AF 2021H is suitable for LLDPE film structures below 50 μm. It cures quickly without negatively affecting the coefficient of friction of the film, making it a reliable choice for thin-film flexible packaging applications.
Q
What equipment types are compatible with these adhesive products?
AS 3775/AS 3775H is compatible with both Dry Type laminating machines and Flexo printing equipment. AF 2021/AF 2021H is designed for Solvent-Free laminating machines. Neither product is currently listed for Coating Machine applications.
