Printing expiry dates on flexible packaging is essential for ensuring product safety, compliance, and traceability. Several methods are available for printing expiry dates on flexible packaging, each with advantages and limitations. Here are some popular options:

  1. Continuous Inkjet (CIJ) Printer:
    CIJ printers are widely used for printing expiry dates on flexible packaging because they can print directly on moving products on a production line. They offer high-quality, durable prints and can handle a variety of substrates, including flexible films and pouches. Choose an ink specifically designed for flexible packaging materials to ensure proper adhesion and durability.
  2. Thermal Inkjet (TIJ) Printers:
    TIJ printers use heat to eject ink droplets from nozzles onto the flexible packaging surface. They produce high-resolution prints and are suitable for applications requiring fine details or smaller text. TIJ printers work well for printing expiry dates on various flexible packaging materials, such as plastic films and laminates. Select an ink that is compatible with the specific flexible packaging material for optimal results.
  3. Thermal Transfer Over Printer (TTO):
    TTO printers use heat and pressure to transfer ink from a ribbon onto the flexible packaging surface. This method provides high-quality, durable prints and is particularly suitable for printing on thin films and labels used in flexible packaging. TTO printers offer excellent print resolution and can produce sharp, clear text, barcodes, and graphics.

When selecting a method for printing expiry dates on flexible packaging, consider factors such as the packaging material, production speed, required print quality and durability, and the complexity of the design. Each method has advantages and limitations, so choose the one that best fits your needs and requirements.

To ensure successful expiry date coding and marking on flexible packaging, follow these best practices:

  • Choose the appropriate printer and ink/ribbon based on your packaging material and application requirements.
  • Regularly maintain and clean the printer to ensure consistent print quality and prevent downtime.
  • Test the adhesion, readability, and durability of the printed expiry date on the flexible packaging material before full-scale production.
  • Implement a quality control system to monitor and verify the accuracy of the printed expiry dates throughout the production process.
