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, offering high initial tack and fast curing. 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.
Q
Are these adhesives suitable for retort packaging applications?
Yes. 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 well-suited for demanding retort packaging requirements.
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 high slip agent content, and it is also suitable for heavy-duty packaging applications requiring strong bond performance.
Q
Does AF 2021/AF 2021H affect the coefficient of friction of LLDPE film structures?
No. AF 2021/AF 2021H is engineered to cure rapidly without affecting the coefficient of friction of LLDPE film structures below 50 μm, ensuring the film's surface properties remain consistent throughout the lamination process.
Q
What types of packaging equipment are compatible with these adhesive products?
AS 3775/AS 3775H is compatible with dry-type lamination machines and flexo equipment. AF 2021/AF 2021H is designed for solvent-free lamination equipment. Please refer to the product compatibility table above for a full overview of suitable equipment types.
Q
What are the appearance quality benefits of using AS 3775/AS 3775H for PET/AL and MPET structures?
AS 3775/AS 3775H provides superior leveling and excellent surface wetting, resulting in high transparency and a soft adhesive layer. It effectively eliminates white spots in PET/AL and MPET laminate structures, delivering an excellent final appearance for daily chemical flexible packaging products.
