Why is printing on plastic packaging bags more challenging?
Plastic packaging bags are widely used for food, household products, personal care products, and other consumer goods.
During production, these bags often need more than just a brand name. Manufacturing dates, expiry dates, batch numbers, barcodes, QR codes, and other traceability information may need to be printed directly onto the packaging.
For applicable products sold in Russia, Chestny ZNAK identification codes may also need to be applied as part of the country's product traceability system.
But printing all this information on plastic film is not always straightforward.
PE, PP, PET, and laminated films have smooth, non-porous surfaces. Ink tends to sit on the surface rather than absorb into the material. This can lead to poor adhesion, smearing, slow drying, or codes that become difficult to scan.
Then add high-speed production lines into the mix, and printing a small traceability code can quickly become a production headache.
So, what should you look for in a printing solution?

Why use NAXJET UV inkjet printing?
NAXJET combines high-resolution piezo inkjet printer technology with UV-curable ink and UV curing. The printer places ink precisely onto the packaging surface, while UV light quickly cures the printed information.
This makes the technology suitable for printing high-resolution text, barcodes, QR codes, and variable data on suitable non-porous packaging materials.
That's where the NAXJET High Resolution UV Inkjet Printer comes in.
For applicable products, in addition to printing integrity labels, the following information can also be printed:
Manufacturing and expiry dates
Batch and lot numbers
Barcodes and QR codes
Serial numbers
Product information
Logos and other variable content

If you are printing Chestny ZNAK codes or other variable information on plastic bags, send us your packaging samples and coding requirements. NAXJET can test print quality, ink adhesion, and code readability to help identify a suitable UV inkjet solution for your application
