Food: Packaging Against Waste

Marking compostable film without printing

In order to provide optimum solutions to companies for coding and marking their food packaging, at the Domino Laser Academy in Hamburg, experts from the company are researching and experimenting with new substrates. “We spend a lot of time analyzing new packaging materials. Due to the new European legal requirements for recycled plastics, around 95 percent of the food packaging samples we need to test are recycled or recyclable plastics. Our fiber and uv lasers offer many good solutions for coding these substrates. We are however convinced that in the coming years, the demand for compostable solutions will increase. We therefore want to be prepared to offer our customers relevant advice and solutions for these new materials”, says Dr. Stefan Stadler, team leader at the Domino Laser Academy. According to this focus, the laser team has tested the compostable NatureFlex film products by the Japanese company Futamura regarding their suitability for laser coding. The laser produces a crisp, white code on the film without damaging the integrity of the original film, changing the chemical composition, or affecting the properties of the moisture barrier. The print-free coding method does not require additional materials on top of the compostable substrate, which should make gaining certification for the final packaging much easier.
