Industrial Inkjet Printer for Flexible Packaging Explained

An industrial inkjet printer for flexible packaging allows companies to print variable information (such as expiry dates, batch numbers, barcodes, QR codes, serial data, logos, graphic design) directly onto film, pouches, sachets, wrapper and laminate without stopping the production line.

Depending on the type of ink and technology used by the printer, it can produce expiry date, batch number, barcode, QR code, serial data, logo and graphic design. With so many SKUs to manage, inkjet provides speed, flexibility and print control.

What Is an Industrial Inkjet Printer for Flexible Packaging?

An industrial inkjet printer is a non-contact system that deposits controlled droplets of ink onto a moving substrate.

Unlike office equipment, industrial equipment is designed for continuous operation, line integration, repeatable positioning and harsh factory environments. Packaging films are typically thin and smooth.

Therefore, print quality is dependent upon the printhead, ink chemistry, curing method, web tension and line speed.

Why Use Industrial Inkjet Printers for Flexible Packaging?

Manufacturers use an industrial inkjet printer for flexible packaging because digital printing enables them to change information without having to replace plates or cylinders.

Digital printing supports variable data, short runs, regional packaging, promotions and frequent product changes.

As an experienced brand, we are familiar with the common challenges faced by manufacturers that they address in their selection process.

Based on our experience at Markcom Global, buyers prioritize readable codes, reliable adhesion, quick setup and easy line integration. A good system will help manufacturers eliminate manual labeling, coding mistakes and excessive amounts of packaging materials, and industrial inkjet printers are the best solution.

Types of Industrial Inkjet Printers for Flexible Packaging

Each technology serves a different production purpose. The table below compares these technologies.

Technology	Main Strength	Typical Use	Key Consideration
CIJ	High-speed coding	Dates and batch codes	Moderate resolution
TIJ	Sharp output	Barcodes and text	Ink compatibility
Piezoelectric	Broad ink choice	Graphics and variable data	Integration compexity
UV inkjet	Instant curing	Durable premium printing	Curing and migration

• Continuous Inkjet (CIJ) Printers

CIJ printers continuously circulate ink and direct selected droplets onto the package. CIJ printers are suitable for high speed lines and are commonly used to print dates, lot codes and traceability information.

• Thermal Inkjet (TIJ) Printers

TIJ printers heat up inside the cartridge and eject precise droplets. TIJ printers produce high resolution text, barcodes and QR codes and are easy to maintain. However, TIJ printers require that the ink adheres to non-porous films and dries within the available line distance.

• Piezoelectric Inkjet Printers 

Piezoelectric printheads utilize electrical pulses to eject ink when needed. Due to their wide range of compatible inks, piezoelectric printheads are ideal for producing detailed graphics, large format prints and dynamic data.

• UV Inkjet Printers

UV printers cure ink instantly using ultraviolet light. This produces durable, smudge proof images. Manufacturers need to assess curing time, potential migration risks and whether or not the ink comes into direct contact with food products.

Applications of Industrial Inkjet Printers in Flexible Packaging

An industrial inkjet printer for flexible packaging can be applied to several regulated and consumer-facing sectors, including:

• Food Packaging

An industrial inkjet printer can print expiry dates, batch numbers, QR codes and promotional information on snack wrappers, frozen food bags, sachets and stand-up pouches.

• Beverage Packaging

Applications include drink sachets, refill pouches, shrink sleeves and secondary films that require moisture resistance.

• Pharmaceutical Packaging

The applications may include lot identification, expiry date, serialization and machine-readable codes on blister foil, sachets and sterile pouches. 

• Personal Care and Cosmetics Packaging

The usages include printing batch details, shade codes and graphic designs on refill packs, sample sachets, masks and pouches.

• Household and Chemical Product Packaging

Applications include printing codes on detergent pouches, cleaner refills and chemical sachets that are resistant to friction, moisture and exposure to the product itself.

Key Features to Look for in an Industrial Inkjet Printer

When considering purchasing an industrial inkjet printer for flexible packaging, you should consider line speed, resolution, throw distance, ink adhesion, drying time, connectivity and compatibility with your production controls.

Features that can add value include automatic date coding, database integration, barcode creation, message storage, nozzle monitoring, operator access control and vision inspection.

In addition, be sure to always test the actual film. Factors such as coatings, laminate structure, surface treatment and slip agents can affect adhesion.

Frequently Asked Questions (FAQ)

• Can inkjet print directly on plastic film?

Yes, when the ink, surface treatment and drying or curing method correspond with the film.

• Which technology is best for high-speed date coding?

CIJ is commonly chosen for fast coding while TIJ is better suited for applications that demand crisp text or machine-readable codes.

• Can one printer accommodate multiple types of packaging formats?

Typically yes; however, mounting position, sensors, ink type, message settings and print distance may need to be adjusted accordingly.

Benefits of Industrial Inkjet Printers for Flexible Packaging

Advantages include rapid changeovers, variable data printing capability, non-contact printing capability resulting in less pre-printed stock required and improved traceability of products. Digital control also enables shorter runs and late stage customization.

Industrial inkjet is now considered an integrated production technology combining printheads, ink delivery systems, substrate transportation mechanisms, drying mechanisms and workflow control systems.

Therefore, selecting the appropriate industrial inkjet printer for flexible packaging requires evaluation of substrate characteristics, code requirements, production speeds, durability targets and regulatory requirements.
