Gecko Frontal Vantage

Printing inks for flexible packaging

A full colour range of pigmented nitrocellulose mono solvent printing inks, designed for the application of surface printing for gravure printing.

Application

Flexible packaging for PVC films and PVDC-coated films.

Use in surface printing

The Gecko Frontal Vantage series can be used for the standard surface printing applications. If an improved scratch resistance should be needed, our Wax Additive solution can be used in the amount of 2-4%. This additive improves the scratch and rub resistance. This Series is not suitable for pasteurisation and sterilization. Given the wide variety of PVC and PVDC-coated film commercially available, a print test before the actual industrial run is strongly recommended.

Gecko Frontal Alu

Mono solvent printing inks for flexible packaging

A full colour range of pigmented nitrocellulose printing inks, designed for gravure printing applications on aluminium and plastic foils. This series is also available as a mono solvent ink series (Gecko Frontal Alu MS).

Application

Flexible packaging for food and beverage products. The Gecko Frontal Alu Series is specific for aluminium but can also be used for surface printing on chem PET, acrylic-coated-BOPP, paper and BOPP. It can be used on BOPP for lamination. The lamination bond depends on the substrate quality, on the type of adhesive and the amount applied. Evaluate before printing that the surface treatment of PP is ≥ 38 dynes/cm. When printed on PP (except in the case of Acrylic coated PP), all the inks of the series should be activated with our recommended Adhesion promoter in the amount of 5% (please consult technical team for the same.

Use in surface printing

Gecko Frontal Alu can be used for the applications of external standard printing. When not protected by over print varnish we suggest to add our special Additive Wax Paste in the amount of 2-4% in order to assure greater scratch resistance. This additive increases the scratch and rub resistance but does not have to be added for applications intended for lamination. If the application requires high mechanical resistance or bears high blocking risk, the use of a dedicated Gecko Frontal ink series is strongly recommended. For applications where ink-to-ink contact may occur (such as in folded packages, or where packages are stacked) Gecko® Frontal Alu should not be used.

Print Process

Rotogravure for surface printing and lamination.

Note

Gecko Frontal Alu inks are not suitable for thermal process like sterilization and pasteurisation. If it is desired to re-use the residual inks containing the Adhesion Promoter for a new print work, it is recommended to test this inks to verify the adhesion to the support and, where needed, to newly add the additive, in order to achieve an optimal adhesion.
