Thermal transfer (TTO) is the natural solution when the marking is to be applied directly to the thin plastic film before the tray is sealed.
Because the plastic film is still flat and controlled inside the thermoforming machine, the printer can place the marking with very high precision, resulting in a sharp and clear print without affecting production speed.
TTO is primarily used to write:
For best results, we recommend that the plastic film is already provided with a special marking area in the design phase where variable information is to be placed. A light or white box, for example, provides significantly better contrast and makes both text and codes easier to read and scan.
However, once the plastic film has been sealed over the tray, TTO is no longer a suitable option. The technology is developed to print on the flat film before the actual packaging is completed.
The Linx TT1000 thermal transfer printer provides an ideal printing solution on flexible packaging in a variety of industrial applications.
This TTO printer offers easy date and batch marking, making it perfect for printing variable information on…
The Linx TT500 is designed to deliver low total cost of ownership and increase production line efficiency with easy date coding on food bags
Inkjet marking is mainly used when the pre-packaged product has already left the packaging machine.
Information can then be applied directly to the sealed plastic film or to the side of the tray, depending on how the production line is designed.
The method is usually used to label:
Inkjet marking is a flexible and cost-effective solution, especially when only variable information needs to be added to the finished packaging.
For simpler date marking, high-resolution inkjet printers (TIJ) can also be an option.
The Linx 9900 series gives you reliable and flexible ink marking with minimal downtime and easy handling – designed to last…
The Linx 9940 Spectrum delivers high-contrast marking at high speeds – with high precision and maximum uptime.
The Linx 9830 offers stable and affordable labelling for everyday production – a smart entry-level model without compromising on quality.
Labelling almost always occurs after the food tray has been sealed and the finished product has left the production line.
The finished packaging is then stable and easy to handle, which allows the label to be applied with very high precision.
Labels are used both for product information and for marketing, but can also serve a function as a sealing or security label.
Depending on the product and wishes, the label can be applied in several different ways, for example:
This type of solution is often used when the label is to contain extensive product information, branding, or act as a guarantee that the packaging has not been opened.
Since the label is applied to the finished product, the packaging process itself is not affected, which provides great flexibility when changing products or using different label designs.
Top labelling of products – with up to 300 units/min.
Bottom labelling of products – with up to 300 units/min.
Top and bottom labelling of products – with up to 300 products/min.
C-wrap labelling around the front, top and bottom – for unstable products.
Full-wrap (D-wrap) labelling on four sides of the product.
Energy-efficient label applicator with support for both thermal transfer and direct thermal.
Often, food tray packaging takes place in a thermoforming or tray sealing machine where the product is placed in the tray before being sealed, often in a modified atmosphere (MAP), to extend shelf life.
Labelling on food trays is an important part of the process and contains information such as best before dates, batch numbers, production dates, barcodes and traceability information. Based on our experience, the choice of labelling method is mainly about when in the production line the labelling should take place – before the tray is sealed or after the finished package leaves the packaging machine.
If the information is to be printed directly onto the thin plastic film, thermal transfer (TTO) is the obvious choice. The technology provides high print quality and very good control over the placement of the marking before the package is sealed.
However, when the food tray is pre-packaged, inkjet marking or labelling is often the most effective option. Inkjet marking is ideal for date and batch information, while labelling offers greater opportunities to combine variable information with product design, marketing and various types of closure solutions.
By planning the labelling already when the production line is designed, the right technology can be integrated in the right place, providing stable production, high readability and secure traceability throughout the food chain.
