Gravure H.R. Polyester lamination inks (Reverse Printing)

These inks are specially suitable for printing of reverse polyester films possessing good printability, good light fatness, at varying press speeds. Good adhesive lamination characteristics thus satisfying the lamination requirement with aluminum foil, polyethylene film, paper and board for a variety of packaging application.

The prints can be laminated with the usual polyurethane based two-component adhesive.

Features:
This ink provides good adhesion on treated polyester film. In case of special requirements to compound stability in-line corona pre-treatment of the respective substrate materials is recommended.

Ink Reducer:
Inks are reduced to print application viscosity by recommended reducer, a mixture of MEK and Toluene. Where printing is done at very high speed a mixture of Toluene and Ethyl Acetate can also be used. The recommended retarder is MIBK. Retarder, however, should be avoided in order to prevent from retention of solvents.

Wash Up:
The recommended reducers can be safely used for cleaning of wash up of Gravure cylinders.

Shade Range:
Pigmented as well as transparent (metal complex dyes based) colors in full range are available. Specific shades can be matched against costumer's demand.

Lamination:
Bond strength of laminate is very much dependent on the adhesive quality, ink deposition weight, adhesive coating weight, nature of substrates laminated ad nature of the job. It is therefore recommended that right quality of adhesive be selected and uniformity of coating weight is properly controlled in order to get standard lamination results. Curing of laminates at controlled temperature and humidity for a minimum of 48 hrs is indispensable to achieve best lamination bond value.
