Industrial Adhesives UAE for Packaging & Paper

An often-underestimated factor in the success of any bonding application is the method used to apply the adhesive. The most perfectly formulated adhesive will fail to perform if it is not dispensed onto the substrate in a consistent, controlled, and repeatable manner. The right dispensing system is as critical as the adhesive itself. Investing in the appropriate equipment not only ensures bond quality but also minimizes waste, reduces cleanup, and maximizes production speed. The choice of system depends on several factors, including the type of adhesive (e.g., water-based, hot-melt), its viscosity, the required application pattern (e.g., full coverage, bead, dot), and the scale of production.

For liquid adhesives like Kubron's water-based formulations, two of the most common automated dispensing methods are roller coating and jetting. Roller coating systems are the workhorses of the paper converting and lamination industries. They use a series of rollers to pick up adhesive from a tray (the glue bath) and transfer a thin, uniform film onto a moving web of paper or film. The thickness of the application can be precisely controlled by adjusting the gap between the rollers (the 'nip'). This method is ideal for covering large surface areas quickly and efficiently, and it is the standard for high-speed, roll-to-roll applications.

Nozzle or jet dispensing, on the other hand, is used for applying precise beads, lines, or dots of adhesive. This is common in packaging for applications like case and carton sealing, as well as in product assembly. The adhesive is pumped under pressure to a nozzle head, and a valve (often electronically controlled) opens and closes to dispense the required amount. Modern systems, frequently controlled by robotics or PLCs, can apply complex patterns at very high speeds with exceptional accuracy. This method is ideal for applications where the adhesive needs to be placed in a specific location, such as the flap of a box, and it minimizes adhesive consumption.

For hot-melt adhesives, the system consists of a heated tank (melter), heated hoses, and a heated application head or nozzle. Maintaining a consistent temperature throughout the entire system is critical to keeping the adhesive at its optimal application viscosity. For manual or semi-automated processes, simple pressure pots and hand-held valves or brushes are often used. While less precise than automated systems, they can be effective for lower-volume or custom work. Regardless of the system's complexity, the core principles remain the same: consistency and control. The goal is always to apply the right amount of adhesive in the right place, every single time. At Kubron, our technical service team frequently advises clients on not only the right adhesive but also the right dispensing strategy to ensure their process is as efficient, clean, and reliable as possible.
