Innovative Eurolog technology integrated into the sealing tray: cutting, sealing and reinforcing in a single step

Innovative Eurolock technology integrated into sealing jaws: cutting, sealing and reinforcing in a single movement

In packaging lines where speed, reliability and hygiene are paramount, creating a Eurolock (also known as a Eurohole) often constitutes an extra process step. Many systems therefore use separate blades or punching mechanisms, which can lead to additional wear, contamination and inaccurate results.

Delba has developed a solution that eliminates these drawbacks: an integrated eurolock mechanism within specially designed sealing jaws, enabling cutting and sealing to take place in a single fluid motion without major modifications to the machine.

A eurolock without extra parts: how our solution works

Our sealing jaws are designed so that the eurolock is cut directly during the sealing process.

A balanced combination of pressure and temperature creates the desired hole without the need for extra blades, springs, die-cutting parts or mechanical interaction.

The benefits at a glance:

• No machine modifications required
• You simply replace the existing jaws with our version; the rest of the unit remains unaffected.
• Less wear, less contamination
• As no moving parts are required, there is virtually no residual contamination, unlike with traditional die-cutting systems.
• Quick and easy adjustment
• Adjusting the Eurolock mechanism takes just seconds. No complex calibration or extra tooling.
• High accuracy and consistent quality
• The Eurolock is formed identically every cycle due to the fixed geometry in the sealing jaw.

Additional reinforcement of the Eurolock

In addition to cutting the hole, we can optionally lightly fuse the film around the Eurolock.

This creates a reinforced edge, which offers significant advantages, particularly with certain film types, such as:

• reduced risk of tearing during transport or display
• a neater finish
• increased load-bearing capacity of the suspension points

This additional process does not require extra cycle time as it is fully integrated into the sealing process.

Flexible application: Eurolock as an optional feature

For manufacturers wishing to produce variants with and without a hanging hole, we offer sealing jaws that are modular and constructed in segments. The operator can easily determine whether the Eurolock segment is used or not.

This provides maximum flexibility without changeover time or additional machinery.

American version? Same principle, same benefits

Our technology is not limited to European Eurolock shapes.

The American hole shape can also be produced in the same integrated manner: cutting, sealing and, if necessary, reinforcing in a single process.

Conclusion: simplicity, reliability and production benefits in a single design

By fully integrating the Eurolock into the sealing jaw:

• additional mechanical parts are made redundant
• hygiene and reliability are improved
• maintenance is reduced
• production reliability is increased
• the line remains flexible in terms of configurations

The result is a cleanly finished, consistent Eurolock achieved without additional process steps or complexity.
