Types of Lamination Adhesives for Flexible Packaging

How Are Flexible Packaging Adhesives Applied?

Flexible packaging adhesives manufacturers primarily apply adhesives using roll coating techniques. In the coating unit of dry laminators and extrusion machines, both utilize a gravure cylinder and a rubber pressing roll. The lines and depth of cells on the coating cylinder significantly influence the dry coating weight of solvent-based laminating adhesives. Notably, the coating cylinder remains unheated, which is a crucial aspect for flexible packaging adhesives manufacturers to consider during production.


On the other hand, the coating unit of solventless laminators consists of five rollers: three steel rolls and two rubber rolls. The steel rolls are heated, which enhances the application process. For flexible packaging adhesives manufacturers, the final coating weight of solvent-free polyurethane adhesive is particularly affected by the speed difference between the transferring roll and the coating roll, demonstrating the importance of precision in the application process. By understanding these methods, flexible packaging adhesives manufacturers can optimize their adhesive application for improved performance and quality in flexible packaging solutions.
