Printing on Flexible Packaging | InkJet, Inc.

Across a number of industries, flexible packaging stands as one of the most valuable and frequently used substrates on the market today. An umbrella term used to describe a range of packaging forms constructed from plastic, paper, aluminum foil, coated paper, or film, flexible packaging is valued for its cost-effectiveness and ability to prolong shelf-life. As such, bags, pouches, packages, and cartons made from flexible packaging are commonly found throughout the food industrybeverage packagingpharmaceutical development, and personal care/cosmetics, among others.  

Whether a company is producing bagged snack food or pharmaceutical blister packs, both supply chain guidelines and federal regulations require them to place traceable codes and markings on their products.  

Required codes frequently include:  

  • Expiration/best-by-date codes
  • QR codes
  • 1-dimensional barcodes
  • 2-dimensional barcodes 
  • Data matrices
  • Serial numbers
  • Lot codes
  • Batch numbers

If these codes are missing, poorly placed, or contain incorrect information, companies may need to perform costly recalls, pay penalties, risk bad publicity, and/or sour supply chain relationships. Fortunately, industrial Tetra Pak printing isn't difficult when you have the expert help of InkJet, Inc. 


By offering an array of quality printers and diverse ink options, InkJet, Inc. can help your company ensure traceable markings are placed properly and consistently.

Continuous Inkjet Printers: DuraCode Touchscreen, Keyboard, and Pigment

Continuous inkjet (CIJ) printers are non-contact production line printing systems designed to mark substrates moving at up to 300 m/min. Thanks to powerful ink circulation systems, CIJ printers can operate up to 24 hours daily without downtime. The speed, wide ink compatibility, and versatile printheads of CIJ printers allow users to mark thousands of products a day with highly legible codes. 

InkJet, Inc. carries three CIJ systems:

  1. DuraCode Keyboard
  2. DuraCode Touchscreen
  3. DuraCode Pigment Printer

All DuraCode systems can mark porous and non-porous substrates at speeds up to 320 m/min. Equipped with an IP55 outer structure and able to operate in temperatures ranging from 41-113° F, the DuraCode CIJ can withstand potentially hazardous environmental elements to deliver consistently excellent results.            

The DuraCode Keyboard and Touchscreen offer the same specifications and compatibility with ink formulas. The only difference between them is their input medium. The DuraCode Pigment has identical specifications as the DuraCode Keyboard and Touchscreen but uses pigmented ink instead of dye ink


See the chart below for a closer look at the DuraCode models’ most important specifications.

Thermal Inkjet Printers: Anser U2, X1, and A1 Models

Thermal inkjet (TIJ) printers are smaller, lighter, and more cost-effective than CIJ systems. While CIJ systems typically weigh around 100 lbs and can cost around $10,000, most TIJ models weigh 5-10 lbs and cost as low as $1,499.00.   

Although thermal inkjet systems are compact and lightweight, they offer impressive coding specifications. For example, the Anser U2 Smart can create 400 x 300 DPI codes up to 0.5” tall (1” tall with the Anser U2 SmartOne). Higher-end TIJs like the Anser X1 can create 600 x 600 DPI codes up to 2” tall with stitched printheads.   

TIJ printers are often designed for slower speed lines, and intermittent coding tasks including environments with tight production line space, but some models also offer high-speed capabilities. InkJet, Inc. carries numerous TIJ printers of varying specialties and price points. Our current options include:

The Anser U2 Smart and SmartOne Thermal Inkjet Printer

The Anser U2 Smart and SmartOne Thermal Inkjet Printer: Compact and cost-effective, the Anser U2 Pro-S is an excellent choice for rigid plastic printing in applications that do not require CIJ-level marking speeds. The Anser U2 Pro-S offers a 76.2 m/min max printing speed, 400 x 300 DPI max resolution, 0.5” max print height, intuitive operation, and easy installation. 

The Anser A1 Thermal Inkjet Printer:

The Anser A1 Thermal Inkjet Printer: The first all-in-one TIJ that offers 2” printing and mid-message DPI adjustments, the Anser A1 is both powerful and affordable. Built with 2 cartridge slots, the A1 can create 2” tall markings with varying DPI elements (e.g., 300 DPI QR code with 150 DPI text). The A1 maxes out at 300 m/min for product marking applications with certain cartridges. Users control the A1 through a large touchscreen interface.

The Anser X1 Thermal Inkjet Printer

The Anser X1 Thermal Inkjet Printer: Even though the Anser X1 is a thermal inkjet printer, you wouldn’t know that from its spec sheet. With printing speeds up to 300 m/min, the Anser X1 is one of the most powerful TIJs on the market today. Beyond industrial speed marking, the Anser X1 offers a 600 DPI max resolution, a 2” max print height (with stitched printheads), IP66 protection, and the ability to control two production lines simultaneously.
