What Is a Cold Glue Spray System?

A cold glue spray system is an automatic adhesive application system used to apply water-based glue onto products without heating the adhesive.

It is widely used in:

• Corrugated box production

• Folding carton manufacturing

• Paper bag production

• Book binding

• Luxury packaging

• Furniture assembly

• Packaging automation lines

Unlike manual gluing, a cold glue system can apply adhesive accurately and consistently, helping manufacturers improve product quality and production efficiency.

How Does a Cold Glue Spray System Work?

A typical cold glue spray system includes:

• Controller – controls glue patterns and timing

• Glue Pump – supplies glue with stable pressure

• Glue Guns – apply glue onto the product

• Sensors – detect product position

• Glue Tank – stores adhesive

When the product passes the sensor, the controller sends a signal to the glue gun, which sprays glue in the required pattern.

The system can apply:

• Dot glue

• Line glue

• Intermittent glue patterns

Different glue patterns can be selected according to the production process.

Why Use a Cold Glue Spray System?

Compared with manual gluing, automatic glue application offers several advantages:

✔ More accurate glue application
✔ Reduced glue consumption
✔ Cleaner production process
✔ Stable product quality
✔ Less manual work
✔ Suitable for high-speed production

For packaging manufacturers, precise glue application can improve bonding quality while reducing adhesive waste.

Common Applications

Cold glue spray systems are commonly installed on:

• Folder gluers

• Flexo folder gluers

• Paper bag machines

• Folding machines

• Rigid box machines

• Packaging assembly lines

They are suitable for many packaging products, including cartons, paper bags, gift boxes, books, and corrugated boxes.
