Primarily packaged products are grouped and positioned in secondary packaging to be transported, stored, or presented on sales shelves. The variety of packaging materials and packaging machines is large. Robatech’s adhesive application systems can be used in a wide range of applications, also in on-demand packaging machines for e-commerce. They apply hot melt adhesives economically and still glue secondary packaging reliably.

Adhesive Application Systems in the Packaging Process 

Whether you collect and position primarily packaged products into secondary packaging via top-loading, vertical or horizontal cartoning, the adhesive process is essentially the same:

Thermoplastic adhesive is melted, delivered, and applied by application heads to side, bottom, or lid flaps of flat cardboard blanks, pre-folded cartons, or other packaging materials - from the bottom, top, or side. In terms of adhesive application, it does not make much difference, whether the secondary packaging is a wrap-around carton or a folding carton. What is important:

  • Every bead and every dot of adhesive must be applied repeatably and precisely to the right spot, with the right length and the correct amount.
  • The gluing must hold reliably so that the packaging and products survive transport undamaged.
  • The adhesive application must be neat, as secondary packaging, such a half or display cartons, multipacks, or trays usually end up directly on sales shelves.


Flexibility through Modularity. Which Adhesive Application System is Right for You?

An adhesive application system for gluing secondary packaging basically consists of a melter, heated hose, and application head. Robatech's systems resemble a modular kit, from which you can select the parts that add real value to your packaging machine or packaging process.

Are you focusing on reducing operating costs? 

Then, for example, these options can help you save on adhesive, energy, and maintenance costs:

Or do you, as a machine manufacturer, want to offer your customers different adhesive application systems that you can integrate easily and in a space-saving manner? 

We have a wide range of products available for you.

  • Select robust, affordable application heads with slow bead application for gluing transport cartons or multipacks.
  • Use electromechanical application heads for fast bead or dot application. They glue individually packaged products precisely and neatly.
  • Use multiple application heads if adhesive has to be applied to cartons in many spots. This keeps your system compact, because multiple application heads are supplied with adhesive via just one heated hose.
  • Combine the right system components for dry or wet operation.
  • Opt for system components that further increase the operational safety and degree of automation of your overall system.
