DF Inks Advances Sustainable Printing with PU Ultima 

DRUCKFARBEN Group continues to strengthen its pipeline with its PU Ultima series and the expansion of its portfolio with UV Ultra Cure Flexo Inks. 

This launch reinforces its commitment to delivering high-performance solutions for the flexible packaging industry.

PU Ultima

Developed in alignment with circular economy principles, PU Ultima systems are NC-free, PVC-free, and compatible with mono-material packaging structures, supporting compliance with emerging regulatory frameworks such as the Packaging and Packaging Waste Regulation (PPWR).

The portfolio includes three distinct systems:

• PUF for flexographic printing 
• PUR for rotogravure applications 
• PUX is a hybrid PU system with very low nitrocellulose (NC) content, suitable for both reverse and surface printing

Selected PU Ultima products, including matte overprint varnishes, have received “Made for Recycling” certification from Interzero. The certification is based on testing by Fraunhofer IVV and evaluation by bifa Umweltinstitut GmbH, achieving recyclability rates of up to 99%.

UV Ink Technologies

DF Inks is expanding its portfolio with a new range of UV Ultra Cure Flexo Inks, designed for high-value and specialty applications requiring fast curing, precision, and durability.

These systems complement the Group’s existing solutions, enabling converters to access a broader spectrum of solutions tailored to different substrates and performance requirements.

PUX Hybrid

The PUX hybrid system represents a significant technological advancement, offering a universal solution for standard-demand BOPP and PET laminates and surface applications.

Its very low NC content ensures compliance with current and future recyclability requirements, addressing a critical limitation of traditional NC ink systems, which are not aligned with circularity standards.

PUX delivers:

• Higher lamination bond strength 
• Complies with PPWR to help converters transition towards the new recycling guidelines
• Lower solvent retention, enabling near odorless packaging

Operational advantages include:

• Fast lamination capability within 4–6 hours, or immediately with minimal adhesion promoter 
• Improved ink transfer efficiency, allowing reduced ink deposit (gsm) without compromising color strength 
• Lower cost-in-use through optimized printing performance 
• Reduced mechanical wear, extending the lifespan of cylinders, blades, and machine components 
• Universal application across laminates and surfaces, simplifying inventory and ink management
