Inkjet coding systems in vertical packaging machines enable fast and non-contact printing of information such as expiry date (EXP), batch/LOT number, production date, barcodes, and DataMatrix (2D codes) onto product packaging.

In high-speed vertical packaging lines, inkjet coding systems play a crucial role in ensuring continuous production and accurate traceability.

How Do Vertical Packaging Machines (VFFS) Work?

Vertical packaging machines (VFFS – Vertical Form Fill Seal) are systems that fill and package products from top to bottom.

They are commonly used in:

• Powder and granular products (sugar, salt, coffee)

• Food products (nuts, legumes)

• Detergents and chemical products

• Cosmetic products

Since packaging is formed vertically in these systems, coding is typically applied either on the film or directly on the package after sealing.

Advantages of Inkjet Coding Systems

Reasons why inkjet systems are preferred in vertical packaging lines:

✔ High-Speed Coding

Adapts to high production speeds and ensures continuous printing.

✔ Non-Contact Printing

Coding is applied without touching the product, preventing damage to the packaging.

✔ Compatibility with Various Surfaces

Provides effective results on:

• Laminated films

• Plastic packaging

• Aluminum-coated surfaces

✔ Flexible Application

Can print both on the film and directly on the finished package.

Differences Between CIJ and TIJ Inkjet Coding

CIJ (Continuous Inkjet) Coding

• Operates at very high speeds

• Resistant to harsh production environments

• Ideal for continuous production lines
