Frequently Asked Questions
Q
What is the difference between AS 3775/AS 3775H and AF 2021/AF 2021H?
AS 3775/AS 3775H is a dry-type and flexo-compatible adhesive based on a polyether system, designed for high initial tack, high peel strength, and fast curing — ideal for heavy-duty and thick LLDPE substrate applications. AF 2021/AF 2021H is a solvent-free adhesive optimized for metallized and transparent flexible packaging, offering a low coefficient of friction and long adhesive tray life for high-speed production.
Q
Are these adhesives suitable for retort packaging?
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 food and daily chemical packaging applications.
Q
What types of equipment are compatible with these products?
AS 3775/AS 3775H is compatible with dry-type laminating machines and flexo printing equipment. AF 2021/AF 2021H is designed for solvent-free laminating machines. Neither product is currently listed as compatible with coating machines.
Q
Can AS 3775/AS 3775H be used with metallized substrates such as MPET or PET/AL?
Yes. AS 3775/AS 3775H is specifically formulated to prevent white spots on PET/AL and MPET laminate structures, ensuring excellent optical appearance and strong bonding performance on metallized films.
Q
Does AF 2021/AF 2021H affect the slip properties of LLDPE films?
No. AF 2021/AF 2021H is engineered to maintain the coefficient of friction of LLDPE film structures below 50 μm, ensuring that the slip performance of the film is not compromised during or after the lamination process.
Q
What are the primary application areas for these daily chemical flexible packaging adhesives?
Both AS 3775/AS 3775H and AF 2021/AF 2021H are primarily designed for daily chemical flexible packaging. This includes applications such as detergent pouches, personal care product packaging, gas-filled packages, and other consumer goods that require high peel strength, durability, and reliable laminate performance.
