Flowpack/Wrap

Flowpack is used in the food industry for everything from bread and sweets to cheese, meat and frozen goods. The packaging often consists of plastic film that is formed, filled and sealed at very high speeds. Therefore, the printing must be fast, accurate and adapted to moving packages.

Thermal transfer printer, TTO

Flowpack is widely used in the food industry for products such as bread, snacks, cheese and ready meals – and here thermal transfer printers (TTO) are one of the most reliable printing solutions. With a TTO, you can print barcodes, best-before dates, batch numbers and other variable information directly onto the packaging film before it is filled and sealed.

Because the marking is done directly on the film roll, the result is always sharp, high-resolution and durable, even on flexible plastic films that can otherwise be difficult to mark with ink or labels. This makes TTO particularly suitable for flowpack solutions where precision, durability and readability are crucial.

Inkjet printing

Inkjet (CIJ) labelling is a flexible and cost-effective solution for flowpack labelling, especially when it comes to variable information such as batch numbers, best-before dates, and production codes.

The marking can be placed on different zones of the packaging, for example at the weld seam where the surface is more stable, to ensure high readability.

An additional strength of CIJ is that the system can be easily changed over to different product formats or code layouts without stopping production, making the technology ideal for lines with many different SKUs or rapid production changes.

Labelling

Labelling is a flexible option for flowpack, especially when the packaging needs to carry a lot of information. Using print & apply systems, labels can be printed and applied directly to the packaging in real time, making it easy to include variable data such as batch numbers, best-before dates, barcodes or QR codes.

A big advantage of labels is that they can be used to complement a pre-printed base film. Instead of producing many different packaging variants, you can use a standard film and then customize it with labels for language versions, allergen labelling or campaign messages.

With the right choice of material and adhesive, labels can stay on shiny, flexible or damp surfaces, which is a common challenge in the food industry. In addition, labels can provide added design value through special effects such as foiling, holography or transparent material.

Read more about Flowpack/Wrap

Flowpack is used in the food industry for everything from bread and sweets to cheese, meat and frozen goods. The packaging often consists of plastic film that is formed, filled and sealed at very high speeds. Therefore, the printing must be fast, accurate and adapted to moving packages.

The most common marking requirements are batch numbers, best-before dates, and barcodes – information that must remain clear and legible all the way to the consumer.

Thermal transfer printer (TTO)
TTO is the most optimal solution for flowpacks because the printing is done directly on the film roll before the package is sealed. The result is high-resolution and sharp prints of text, logos, barcodes and QR codes. The marking is durable and withstands both cold, moisture and handling in the chain. TTO technology is particularly advantageous for producers who want maximum quality of the codes and can mark both static and variable information in the same step.

Inkjet (CIJ)
CIJ is often used on flowpacks when you want to mark directly on pre-packaged products. It is very flexible and can be placed on different zones, e.g. the weld edge. With special inks, you get good contrast even on shiny or damp surfaces. CIJ is particularly valuable in lines with many product changes - the system can be changed quickly without disrupting the flow.

Labelling
Labelling is a good option when the packaging needs to contain a lot of information, multiple language versions or variable data. With print & apply systems, labels can be printed and applied in real time to the flow pack. Many food manufacturers use labels to complement a pre-printed base film, which reduces the need for many different packaging variants.

Our recommendation:

For the highest print quality and reliability on the film roll: choose TTO.
For fast and flexible direct marking on pre-packaged products: choose ink marking (CIJ).
For extra information, language variations or promotions: select labelling.

With the right technology, we at Logimark ensure that the labelling on your flowpack packaging is clear, durable and adapted to both the product and the production flow.

Questions & Answers (FAQ)

It depends on the need. TTO (thermal transfer printer) is usually the optimal solution as it prints directly onto the film roll with high resolution. Inkjet (CIJ) labelling is flexible for pre-packaged products, and labels are used when additional information or multilingual versions are needed.
TTO writes directly onto the packaging film before it is filled and sealed. The marking is sharp, durable and very precise, even for logos, QR codes and small texts.
Yes. With the right ink, CIJ can produce clear codes even on cold and damp packaging.
Labels are practical when the packaging needs a lot of information, multiple language versions or promotional messages. They can be applied in real time with print & apply systems and often complement a pre-printed base film.
Yes, especially for producers who want high quality printing in high volumes. Although the investment may be higher than CIJ, TTO saves costs in the long run thanks to durable marking, high precision and fewer quality deviations.
Absolutely. It is common to use TTO for batch numbers and best-before dates on the film, and supplement with labels for promotions or language variations.
