Coding and Marking on Flexible Packaging

coding on flexible packaging

Flexible packaging has become increasingly popular in the packaging industry due to its convenience and versatility. Thermal inkjet printing specializes in coding and marking on flexible packaging. This process involves using heat to create small gas bubbles, which further eject ink droplets onto the packaging material. Furthermore, digital date coding on the packaging is also an excellent option for manufacturers as it ensures accuracy and reliability. With the advent of advanced technologies, coding on flexible films has become more smooth and efficient. Whether for inventory or tracking the packaging product, these inkjet date coder results as the best.

    Inkjet Coding and Marking Solutions

    A continuous inkjet (CIJ) coding printer (non-contact printing technology) can quickly print high-quality codes, text, and graphics on various substrates. Food, beverage, pharmaceuticals, and packaging industries mostly use CIJ for marking batch numbers, expiry dates, and barcodes. Here’s an overview of how a CIJ coder works:

    Continuous Inkjet Printer Workings

    1. Ink System:
      The Continuous Inkjet printer has an ink system so that it can reserve ink. The ink, which typically contains solvents, dyes, or pigments, circulates continuously through the system.
    2. Ink Pressure and Circulation:
      CIJ pressurizes the ink and pumps it from the reservoir to the printhead. After passing through the printhead, CIJ collects the unused ink and returns it to the reservoir for recirculation.
    3. Printhead and Nozzle:
      The printhead contains a nozzle with a small opening, usually ranging from 40 to 70 microns in diameter. A piezoelectric crystal inside the nozzle vibrates at a specific frequency, typically between 60,000 and 120,000 times per second.
    4. Droplet Formation:
      As the pressurized ink enters the vibrating nozzle, it breaks into individual droplets due to the vibration effect. These CIJ droplets release in a continuous stream from the nozzle.
    5. Charge Electrode:
      Immediately after the droplets exit the nozzle, they pass through a charged electrode. The electrode imparts an electrostatic charge to each droplet, depending on the intended position of the printable character.
    6. Deflection Plates:
      The charged ink droplets travel through a pair of deflection plates, which create an electric field. Depending on the droplet charge with a more or less electric field, determining their position on the substrate.
    7. Printing on the Substrate:
      The accurately deflected CIJ droplets reach the substrate, creating the desired characters or graphics. Meanwhile, the non-deflected droplets fall into a gutter and return to the ink reservoir for recirculation.
    8. Drying and Curing:
      As the ink droplets land on the substrate, the solvents evaporate quickly, leaving behind the ink on the surface. This process results in a high-quality, permanent print that is resistant to smudging and fading.

    Print with Food Grade Inks

    The Continuous inkjet coder’s ability to print directly on moving products makes it an ideal choice for many industrial coding applications. Additionally, the technology offers high-speed printing, low maintenance requirements, and the capability to produce high-resolution prints with minimal downtime.

    Expiry Date Printer

    Continuous Inkjet Printers are popular for printing variable information, such as dates or batch codes during production. These printers explicitly handle products of different sizes, shapes, or textures, making them prime for many industries. Furthermore, Linx Printing Technologies offer a range of continuous inkjet printers that are cost-effective and efficient. Some features include remote printer monitoring and customer support, concealed and easy-to-clean printheads, error-free touch-screen control, and simple self-service capability. Compared to other industrial inkjet coders, Linx’s printers provide a reliable and quality solution to meet your needs.

    print expiry date on packaging

    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.

    In general, the Linx inks can print with ease on flexible packaging with an inkjet coding machine. Variety of inks and fluids depending on the material and application requirements. Here are some popular ink types:

    inkjet coder for packaging

    1. Solvent-based Inks:
      CIJ printers and some TIJ printers commonly use solvent-based inks. These inks contain pigments or dyes dissolved in a solvent that evaporates quickly. Indeed, leaving behind durable and high-quality inkjet printing on flexible packaging materials. Solvent-based inks offer good adhesion, quick drying times, and resistance to chemicals and abrasion.
    2. Water-based Inks:
      Water-based inks are suitable for use with some TIJ printers and flexographic printing systems. These inks contain pigments or dyes suspended in a water-based solution, making them more environmentally friendly than solvent-based inks. Water-based inks work well on porous substrates, such as paper and uncoated flexible inkjet packaging materials. But may not adhere well to non-porous materials without surface treatment.
    3. UV-curable Inks:
      UV-LED inkjet printers use UV-curable inks and offer excellent adhesion, durability, and resistance to chemicals and abrasion. These inks contain photoinitiators that cure instantly when exposed to UV light. Additionally, creating high-quality inkjet coding on various flexible packaging materials, including plastic films and laminates.
    4. Hot-melt Inks:
      Thermal transfer over printers (TTO) uses hot-melt inks, also known as solid inks. Also, some drop-on-demand (DOD) inkjet printers use hot melt inks. These inks come in solid form, and the print head melts the ink during the printing. As a result, transferring it from a ribbon onto the flexible packaging material. Hot-melt inks offer good adhesion and durability, making them suitable for printing on thin films and labels.
