Correctly distinguish packaging

What is the difference between food and non-food packaging? At first glance, nothing except the contents. But it is precisely this distinction that is essential for closing material loops and returning packaging from post-consumer waste to its original applications.

Masterbatcher Rowa and marker specialist Tailorlux have therefore teamed up to provide information on a new PET compound with marker that can be clearly identified using a hyperspectral camera. “In our technical center, we have produced a flat film from the new PET compound we manufacture, which is almost transparent and can be clearly identified,” emphasizes Rowa Managing Director Bernhard Scheffold. “We have been working with markers for a long time, but until now we used visual spectra for evaluation. With the hyperspectral camera, we work in the NIR range, which allows us further options,” explains Tailorlux Managing Director Tobias Herzog. Both are certain that this innovation is of great interest to the recycling industry, as it can help to improve recyclate quality and close loops.
