Solutions for Folding Carton: Inside and Outside


Introducing SunPak® DirectFood Plus*

Whatever your requirements, Sun Chemical has your folding carton covered – inside and out, with the most sustainable product solutions available for sheetfed offset inks and coatings.

Sun Chemical can offer SunPak DirectFood Plus, a unique ink that offers direct food contact printing opportunities when used in combination with SunSpec SunStar Aqueous Direct Food contact overprint varnishes.

This innovative technology allows you to:

  • Print ‘inside the box’ and replace PE barriers while still ensuring the required grease, oil or water resistance properties of the carton are maintained
  • Use a first sheetfed offset direct food contact ink that prints with similar intensity and stability to that of a standard low migration ink, opening up a whole new world of opportunity for ‘in the box’ printing
  • Ensure color consistency across various substrates through SunColorBox – the digital color management solution that delivers a fully digital workflow in order to communicate color achievability effectively to brand owners and designers

Print knowing you are using a product designed with the highest level of bio-renewable content possible, as verified by Beta Analytics, the world leader in Carbon-14 measurements since 1979.**

Inside the Carton Offering:

By employing unique product solutions designed by Sun Chemical, such as SunPak DirectFood Plus inks and SunStar Direct Food Contact OPV, litho printers can now print inside the box with direct food safe inks and coatings that enable the removal of PE barriers which are commonly found in food grade board or plastic inserts or trays used within the final package, without any compromise on quality.

Outside the Carton Offering:

By utilizing the industry-leading performance of Sun Chemical’s SunPak FSP low migration inks, as with SunPak DirectFood Plus, the highest possible bio-renewable content is achieved is achieved once again.

SunPak FSP inks are designed to provide the best possible stability at extreme high printed speeds (up to 20,000 inches per hour) without any compromise on print quality, ensuring minimal press stoppages that results in reduced waste and downtime costs.

This highly efficient performance can be further enhanced when applying the extended color gamut process using SunECG to reduce the need for special Pantone/spot colors by replacing with a fixed process utilizing up to seven process colors. Backed by SunColorBox and our unique gamut viewer software, SunECG offers an opportunity to reduce the need to change inking units resulting in reduced downtime, waste, energy and solvent through reduced washing.
