How to Choose the Right Glue Application System for Packaging?

Choosing a glue application system depends on more than the type of machine you use. The adhesive, material, glue pattern, production speed, and machine layout all need to be considered.

1. What Type of Glue Do You Use?

The first step is to identify the adhesive.

• Hot melt adhesive requires heating and can be used with EVA, PSA, APAO, or PUR.

• Cold glue is generally used as a water-based adhesive and does not require heating.

The adhesive type determines which glue system, pump, and applicator are suitable.

2. What Material Are You Gluing?

Different materials may require different application methods.

Common packaging applications include:

• Corrugated boxes

• Folding cartons

• Paper bags

• Paper sacks

• Luxury packaging

• Furniture packaging

For example, hot melt systems can be used for box making, paper bags, end-of-line packaging, and other industrial applications.

3. What Glue Pattern Do You Need?

Consider how the adhesive needs to be applied.

Depending on the application, the system may use:

• Glue dots

• Glue lines

• Swirl patterns

• Coating

The applicator should match the required glue pattern and coverage area.

4. What Production Speed Do You Need?

Production speed is another important factor. High-speed packaging lines may require an applicator with a fast response time and a stable adhesive supply.

The glue system should also be able to work with the speed and movement of the production machine.

5. Does the System Need to Be Customized?

Every production line has different installation space, machine structures, and process requirements.

The number of glue guns, installation position, glue pattern, and machine synchronization may all need to be considered.

Choose the System Around Your Production Process

There is no single glue application system for every packaging application. The right solution depends on your adhesive, material, production speed, glue pattern, and machine layout.

KQ Automation develops customized glue application solutions based on the customer's actual production process, helping integrate adhesive application into different packaging machines and production lines.
