Flexible Packaging Adhesives

Focusing on flexible lamination adhesives' R&D and manufacture since 1999, COMENS, one of the leading flexible packaging adhesives manufacturers, supplys the full range flexible packaging adhesives lines, including solvent based, solvent free, water based, and AC agent (primer) for extrusion lamination, from general purpose to high performance.

COMENS flexible packaging adhesives can meet all the requirements and applications, like standup pouch with zipper or spout, slip agent resistance, C.O.F. stable, harsh gear hobbing heat sealing, aggressive hot filling, boiling and retorting with AL foil, heavy duty laminates, ALU-ALU cold forming, aggressive materials resistance and so on.

Besides the functional requirement, our flexible packaging polyurethane adhesive also can meet the operational requirement, such as high running speed, fast curing, high green tack, excellent solvent release, high working solid content, low working temperature, long pot life and so on. And we have the strict product safety policy to make sure we can meet the law and regulations around the world.

Types of Lamination Adhesives for Flexible Packaging

SOLVENT BASED ADHESIVE

Solvent Based Adhesives are powerful bonding solutions that use a solvent as a carrier. These flexible packaging adhesives offer strong adhesion, quick drying times, and are ideal for a wide range of applications.

SOLVENT FREE ADHESIVE

Solvent Free Adhesives, also known as Solvent Less Adhesives, are environmentally friendly adhesives that do not contain any solvents. These adhesives for flexible packaging provide strong bonding without the risk of solvent emissions.

AC AGENT (PRIMER) FOR EXTRUSION

AC Agent (Primer) for Extrusion is a preparatory coating applied before extrusion. This extrusion polyurethane primer enhances the adhesion between the extruded material and the substrate, ensuring a strong and durable bond.

Water Based Adhesive

Water Based Laminating Adhesives are eco-friendly adhesives that use water as a carrier. These flexible laminating polyurethane adhesives offer excellent adhesion, are easy to clean up, and are ideal for laminating applications.

How Are Flexible Packaging Adhesives Applied?

The coating unit of dry laminator and extrusion machine are same, both of them use gravure cylinder and rubber pressing roll. The lines and depth of sell on coating cylinder will affect the solvent based laminating adhesive's dry coating weight. The coating cylinder is not heated.

The coating unit of solvent less laminator is composed by 5 rollers: 3 steel rolls plus 2 rubber rolls. The steel rolls are heated. The final coating weight of the solvent free polyurethane adhesive is affected by the speed difference between transferring roll and coating roll.
