The challenges of Digital Printing in
Flexible Packaging?
Print is just the decoration of the packaging!
• Typical long run lengths
• Majority is reverse printed and laminated to second
film
Lamination equipment is designed for long run lengths
Curing time of lamination up to 7 days
• Requirements of packaging resistance to
Moisture
Chemicals
Oxygen
Grease
Temperature

DigiPrime® 050 Design & Value
• Lamination bond strength is the main extra requirement!
In conventional printing special inks are used for lamination

While keeping advantages from other primers
• Developed for performance in different applications
Pre-Laminated Structures (Surface Print)
Single Film (Surface Print)
Lamination Structures (mostly reverse print)
• Good adhesion to printed film (PP, PET, PE)
• Good lamination bond strength when laminated to a second
film
• OPV adhesion for flexible packaging and label applications
• Improves the transfer and adhesion to film and metalized film
substrates
• Suitable for food contact
• Runability in the PUW
• Water resistance

Structures – Single Film and Pre-laminating
• Corona treatment on printed substrate is essential
• OPV needs to be applied (Post printing) for:
Upgrading heat-seal resistance) up to 160C.
Water resistance (Refrigerator, Freezer)
Modifying coefficient of friction (Static and Dynamic)
Others
Various suppliers of OPV’s water-based, solventbased or 2 component solvent-based

Structures – Lamination Reverse Print
• Corona treatment on printed substrate is
essential
• Corona treatment on the inks, when applying
the lamination adhesive is essential
• Corona treatment on the sealant film when
laminating can improve the bond strength
• Adhesive suppliers who can provide different
lamination adhesives:
Water-based
2 component solvent-based
2 component solvent-free
