HydraLam® NU Lamination Inks, by Coat Well Inks are new-generation gravure printing water-based inks specially developed to achieve high lamination bond strengths for printing and subsequent lamination on films such as BOPP, PET or OPA. It is suitable for medium to high-duty applications such as deep-freeze bags, dried food, or confectionaries. HydraLam® NU Lamination Inks can be laminated with solvent based, 2K solvent less, and water-based adhesives.

Excellent lamination bond strengths are obtained while ensuring good resolubility, transfer, and print characteristics.

HydraLam® Lamination Inks contribute to sustainability

• Enables conversion to water-based printing in flexible packaging.
• Replacement of high volatile solvents with water.
• Lower ink consumption due to high pigment loading and higher solids in the ink.
• Reduced emissions throughout the life cycle.

Key Features & Benefits

• Excellent Lamination Bond Strength.
• Good printability and resolubility.
• Excellent block resistance.
• Designed for sustainable packaging applications.
• Reduced ink costs.

Lamination Bond Strength

• Adhesive penetration into the ink layer(s) is important for bond strength.
• It is possible to use HydraLam® Lamination Inks in PP/ PE extrusion processes with the addition of Cross-linking additive to inks during the print process.

Recommended Dosage for Cross-Linking Agent

• 1 – 2% in all colours (Wt. / Wt.)
• 2 – 4% in last drawn ink/ full coating(Wt. / Wt.)
