Sun Chemical Collaborates With Qualvis Packaging Sun Chemical and Qualvis Packaging, Leicester, United Kingdom, have collaborated to develop a highly sustainable chocolate truffle carton for choc- olate manufacturer Whitakers. The concept enabled Whitakers to transform an ex- isting truffle carton that featured 55 percent plastic into a highly recyclable lightweight fiber-based solu- tion without plastic layer of the same dimensions. The package uses Sun Chemical’s SunPak Direct- Food Plus bio-renewable direct-food contact inks and SunSpec SunStar direct-food contact aqueous varnish on the inside of the carton.

The use of Sun Chemical’s inks and varnish re- portedly eliminates the need for a plastic extrusion in between the ink film and the food product and enables replacement of the existing PET double clam shell housing the truffles with a fibre-based holding structure, while ensuring both a direct food contact safe environment for the truffles comple- mented by functional resistance and barrier proper- ties to maintain the protection and integrity of the carton structure and its contents. This, in combination with the highly bio-renew- able properties of the inks reportedly decreases the overall carbon footprint of the product. SunPak FSP EcoPace low-migration inks and Sun- Coat aqueous varnish are employed on the front of the carton, also contributing to the reduced carbon footprint achievement due to a very high bio-re- newable content made possible by employing a new fossil fuel-free carbon black derived process ink. All inks are also cradle-to-cradle certified. Furthermore, the board is an environmentally sourced material from premium paperboard com- pany and Qualvis partner Holeman Iggesund. The outer cellophane wrap has been replaced with a tear strip built into the carton design to keep the lid in place during transit and on the shelf at retailers.
