Packaging and graphic solutions producer Sun Chemical has partnered with HP to launch sustainable flexible packaging produced with HP’s Indigo digital press and Sun Chemical’s new solventless lamination solution SunLam.
The solution has fast-curing, ultra-low monomer, and has solvent-free properties that can improve sustainability and expand the circular economy of brands.
Under the collaboration, Sun Chemical and HP produced stand-up pouches printed on HP’s Indigo 25K digital press using monomaterial polyethylene (PE) and polypropylene (PP) substrates, and laminated with Sun Chemical’s SunLam solution.
According to Sun Chemical, all-PP pouches received certification from Germany’s institute Cyclos-HTP after testing for a recyclability rate of 96%.
Sun Chemical provided SunLam Adhesives ZA-1000+ZB-301 to produce the PE and PP laminated structures with HP Indigo on standard mono materials with lamination on the Nordmeccanica Super Simplex E-800 solventless laminator.
Sun Chemical global laminating adhesives & cold-seals product director Pierangelo Brambilla said: “The close collaboration between Sun Chemical and HP Indigo is helping develop faster routes to market for flexible packaging.
“By combining HP Indigo digital printing with the fast-curing capabilities of Sun Chemical’s ultra-low monomer adhesive, without compromising the overall quality of the package – a new solution is now available to enable printers and brands to meet the most stringent food safety regulations.”
Brambilla added: “These are just two great examples of how monomaterial PE and monomaterial PP were used to show how the proper selection of lamination adhesives and coatings demonstrate the fast-to-market value proposition of digitally printed pouches while providing more sustainable packaging and consumer choice.”
HP Indigo ww supplies business director Itai Shifriss said: “HP Indigo has been collaborating with Sun Chemical for many years to provide innovative solutions to HP Indigo customers.
“Today, demand for sustainable packaging solutions is driving converters to digital printing which can lower the impact of printing with on-demand production while eliminating plates and cylinders.
“By working together to deliver end to end solutions for HP Indigo customers, we are helping converters and brands grow their digital printing capabilities.”
