PIJ (Piezo Inkjet) Printing Technology: Advantages, Global Trends, and Opportunities in the Pharmaceutical & Medical Markets (Including Thailand)
In today’s pharmaceutical and medical manufacturing landscape, product identification, traceability, and packaging integrity are more important than ever. With growing regulatory requirements and consumer demands, manufacturers need reliable, high-quality coding and marking systems that produce clear, durable results without compromising product safety.
Introduction
Piezo Inkjet (PIJ) printing technology has emerged as a leading solution for pharmaceutical and healthcare packaging. This article explores PIJ advantages, global market trends, and its growing role in Thailand’s pharmaceutical and medical production sectors.
PIJ Printing: What It Is and How It Works
Piezo Inkjet (PIJ) printing is a non-contact technology that uses piezoelectric crystals to precisely eject ink droplets onto a substrate. Unlike thermal inkjet systems, PIJ printers use mechanical deformation (via piezo crystals) to propel ink, enabling reliable, high-resolution printing across a wide range of materials.
Key Characteristics of PIJ Technology:
-
Non-contact printing: No physical contact with the product surface
-
High precision: Extremely sharp text and graphics
-
Versatile media support: Plastics, glass, metals, flexible films
-
Fast drying: Especially when using UV-curable inks
-
Low maintenance: Stable operation in industrial environments
Why PIJ Is Ideal for Pharmaceutical & Medical Packaging
Pharmaceutical and medical packaging requires extremely high levels of clarity, accuracy, and reliability. PIJ printing meets these needs better than many traditional methods.
1. High-Resolution, Crisp Codes
PIJ printers deliver sharp, readable alphanumeric codes, logos, batch numbers, and expiration dates even on curved or textured surfaces like ampoules, blister packs, and syringes.
Example benefits:
-
Better legibility for scanners and human inspection
-
Improved product traceability and quality control
2. Excellent Adhesion on Multiple Materials
Pharmaceutical products often use diverse packaging substrates:
-
Clear plastic (PVC, PET)
-
Flexible foil
-
Glass vials
-
Sterile paperboard cartons
PIJ inks, particularly UV-curable or specialty formulations, adhere exceptionally well on all these materials — ensuring durability and resistance to abrasion, moisture, and handling.
3. Non-Contact Printing = Process Safety
In medical packaging environments, maintaining aseptic conditions is critical. Because PIJ printing requires no contact with the product surface, it:
-
Reduces the risk of contamination
-
Enables integration into clean room production lines
-
Minimizes downtime for cleaning and sanitization
This non-contact feature makes PIJ ideal for sterile pharmaceutical lines, such as eye drop ampoules, injection vials, and blister packaging.
4. Flexible Variable Data Printing
PIJ systems easily handle:
-
Dynamic date, lot, and batch codes
-
2D data matrix barcodes
-
QR codes
-
Serialization data for regulatory compliance
This capability supports complex production requirements in pharmaceutical traceability and anti-counterfeiting initiatives.
5. Fast Drying and Robust Marking Options
When combined with UV-curable inks (such as on Omajet and similar systems), PIJ printing delivers:
-
Instant ink curing
-
Resistance to smudging and solvent exposure
-
Consistent performance in high-speed lines
This is especially important in pharmaceutical environments where precision cannot be compromised.
