Sun Chemical and HP collaborate on sustainable packaging

The pouches have been certified by Germany’s Institute Cyclos-HTP after being successfully tested for a recyclability rate of 96%.
Sun Chemical has teamed up with HP to launch new sustainable flexible packaging which has been produced using the former’s SunLam solventless lamination solution and the latter’s HP Indigo digital printing technology.
As part of the partnership the two companies have developed a series of stand-up pouches, printed using HP’s Indigo 25K digital press. The substrates involved are monomaterial polyethylene (PE) and polypropylene (PP), laminated with the SunLam solution.
The PE and PP laminated structures were produced with HP Indigo using SunLam Adhesives ZA-1000+ZB-301 on standard mono materials with lamination on the Nordmeccanica Super Simplex E-800 solventless laminator.
SunLam itself is intended to help brands improve their own sustainability performance and to expand the circular economy thanks to its fast-curing, ultra-low monomer and solvent-free properties.
Pierangelo Brambilla, Sun Chemical’s product director, Global Laminating Adhesives and Cold-Seals, explained, ‘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.
‘These are just two great examples of how mono material PE and mono material 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.’
Itai Shifriss, HP Indigo’s supplies business director, added, ‘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.’
