Question time … What are my options to mark directly onto film packaging?

Marking and coding directly onto film packaging has several advantages. What you use depends upon what you want to achieve. This quick Q&A will give you a better idea of what will work for you.

Q. What are the advantages of marking directly onto film packaging?

A. The main one is being able to use generic film rather than having product-specific packaging for every single SKU you produce. This saves a lot of money tied up in inventory stocks, as well as the physical space to store it. Direct coding is a highly cost-effective printing solution, particularly if you produce snack foods, confectionery or fresh produce.

Q. So what can I use to code?

A. The most commonly used technology is thermal transfer overprinting (TTO); however, the other alternatives are CIJ (continuous inkjet) and laser.

Q. Why is TTO the most widely used?

A. Firstly, because the technology can print such a broad range of marks, from simple date and batch codes, to more complex barcodes, logos, product descriptions, ingredients lists and nutritional panels. The second point is the print’s clarity and durability — even on flexible film.

Q. Do retailers accept TTO-produced barcodes?

A. Yes, because TTOs produce crisp, resilient printing, barcodes printed with a TTO are high density and fully compliant with GS1 standards. They’re also highly resistant to abrasion and chemicals, as well as climatic changes the packaging may face through the supply chain (think humidity and UV).

Q. Can I integrate a TTO into my existing production line?

A. Absolutely. TTOs can be mounted on packaging equipment, such as vertical form fill machines, and are easily integrated into existing lines.

Q. How fast are TTOs?

A. This technology is actually well suited to high-speed production lines because the thermal transfer ribbon’s smooth, waxy surface creates less friction when coding onto a product.

Q. How robust is the technology?

A. Very. TTOs are designed for reduced downtime and maximised ribbon economy. Another good point for manufacturers is that compared with direct thermal barcode printing, print-head life is frequently doubled with thermal transfer. TTOs are highly efficient printers.

Q. What else can print date codes on flexible film?

A. CIJ is another option, and depending on what you’re trying to achieve, you can also code with lasers.
