But let’s start at the beginning. Java Paper Group is a specialised supplier of high-quality paper and paperboard. They acts as an intermediary between manufacturers, printers, merchants and converters. For over 15 years the company has supplied Art-in-Art with paperboard for various projects. So when Art-in-Art needed help to develop its Lupisulin packaging, Java Paper Group suggested first that they should run trials on Invercote G 300g/m2.

When the trials were conducted they found Invercote much stiffer than the 300 g/m2 competition SBS board, which prompted them to go for Invercote G 260 g/m2 and, as we had suggested, it matched the stiffness of the previous 300 g m2 SBS board,” reports Sagar Java of Java Paper Group.

It was the stiffness despite the lower grammage that persuaded Art-in-Art to consider Invercote. Following several trials, the company chose Invercote based on its good performance in four criteria: shade, foldability without creases, runnability on the machine and dimensional stability. The last-mentioned is crucial to the improved production efficiency.

When packing the Invercote cartons, the end-user found they could run their machine with full capacity and achieve increased productivity without any machine or manpower investment. The dimensional stability of the converted Invercote paperboard helped the cartonator lines run error free and led to a 15% increase in efficiency,” Sagar Java concludes.
