laminating adhesives are used to bond multiple layers of materials together. These flexible lamination adhesives are commonly used in flexible packages and more and more industrial applications . As a leading PU laminate adhesive developer and manufacturer, COMENS supplys series laminating adhesives with excellent bonding strength, chemical resistanc and heat resistance.

How Does Flexible packaging adhesive Work?

Preparation of Surfaces

Before the lamination process begins, the surfaces to be laminated must be checked the surface tension. This ensures the final lamination bonding strength is high enough.

01

Machine Condition Check

The laminating adhesives mixer condition, the lamintors' coating cylinder and each rollers' pre-heating temperature need to be checked before lamination.

Laminating of Materials

Coating adhesives inlcuding laminate to laminate adhesive for flexible packaging onto one material uniformaly, then two surfaces are pressed together, usually under heat and pressure. This causes the flexible lamination adhesives to spread evenly between the surfaces and bond them together.

03

Curing Process

Finally, the newly laminated material needs to cure before next processing. This can take anywhere from a few hours to several days, depending on the type of laminating adhesives used and the environmental conditions. The curing process ensures a strong, durable bond and good chemical & heat resistance.

When Should I Use Laminating Adhesives?

When you can't find an single substrate that matches all your requirements,  then it's time to consider adhesive lamination.

Lamination is a process in which two or more materials are bonded together into one material by laminating adhesives, and these flexible lamination adhesives including industrial laminating adhesive will maintain all the properties of each component.

After Lamination, you will get a material that can meet most of your requirements, with better barrier and heat resistance.

Converters can perform adhesive lamination as a standalone process. Lamination will cost more due to a longer, more complicated labor process.  If you're unsure how lamination will affect the your final cost, ask your converter about pricing and how they plan to laminate to meet your final design.

Benefits of Laminating Adhesives

Enhanced Durability

 Laminating adhesives by Comens enhance the durability of the bonded materials, making them resistant to wear and tear, heat, and moisture. This extends the lifespan of the product.

Improved Appearance

Lamination can improve the appearance of materials by adding a glossy or matte finish. The laminate glue can also enhance the color and texture of the underlying material.

Increased Flexibility

Laminating adhesives allow for the bonding of different materials, increasing the flexibility of design and usage. This is particularly beneficial in industries like packaging and automotive.

Cost-Effective

Flexible lamination adhesives are a cost-effective solution for lamination bonding materials. They reduce the need for mechanical fasteners, lowering production costs and saving time in the manufacturing process.

Laminating Adhesives For Different Applications

Laminating adhesives are versatile lamination bonding solutions used across various industries. These flexible lamination adhesives like PU resin for ink offer durability, flexibility, and improved aesthetics, making them ideal for diverse applications.
