Tetra Pak and other beverage packaging

Inkjet technology is capable of marking on smooth and damp surfaces without the requirement for direct contact, making it very robust in real production environments.

It can easily handle changes in information such as dates, batch numbers and shift codes without requiring changeovers or production stops. It also works well at high speeds, matching the pace of filling lines for milk, juice or cream, for example.

It is precisely the flexibility and operational reliability that make CIJ the natural first choice for most Tetra Pak applications.

Advantages of CIJ on Tetra Pak packaging:

• Tetra Pak packages are already pre-printed with high-quality graphics. CIJ makes it possible to add the necessary information without covering or disrupt the original design.
• The marking can be applied to small areas, for example at the top of the packaging, where it is visible but discreet.
• Since the packaging already contains all visual communication, extra labels are avoided – which saves both material and cost.
• CIJ is well suited for high-speed lines and can handle continuous labelling without slowing down production.
• Perfect for batch numbers, best before dates and other variable information that needs to be readable throughout the product's lifecycle.

Laser can be an option in more specific cases. If production is completely standardized – with the same design, the same location and no need for changes – laser can be integrated into the line for permanent and low-maintenance marking.

It is particularly suitable for highly repetitive operations where the same product is continuously processed. The technology etches the marking directly into the top layer of the packaging – often the plastic laminated surface – providing a permanent and sharp code.

Advantages:

• Marking that is not affected by moisture or wear.
• No consumables
• High precision even at high speeds.
