UPM Specialty Papers, Henkel and Koenig & Bauer have combined their expertise to develop a new recyclable paper packaging, a doypack for food applications such as confectionery, frozen foods and bakery products. This innovative project showcases digital printing solutions while respecting recycling requirements.
The three partners have combined their expertise in paper, coatings and printing to offer food companies an alternative packaging solution to conventional plastics. UPM Specialty Papers is a leading producer of specialty and sustainable papers, including packaging; Henkel is a global specialist in adhesives and coatings; and Koenig & Bauer offers state-of-the-art solutions for digital and analog printing.
A recyclable, durable paper doypack
The pouch is a response to current challenges in the food packaging sector. Made from UPM Asendo barrier paper and printed using a Koenig & Bauer RotaJET digital press, this packaging stands out for its moisture- and grease-resistant properties, while offering good sealability. What's more, it is fully recyclable in existing fiber recycling streams.
Suitable for digital printing and food standards
One of the main features of this doypack is its ability to be printed by a variety of methods, including digital printing, a major asset for brands wishing to personalize their packaging while respecting sustainability criteria. The paper used is compatible with Henkel's barrier coatings, including Aquence Epix BC 6134FL, which enhances moisture protection properties and guarantees food safety.
Towards product industrialization
This pouch is designed to be easily integrated into existing production lines. Although the machines were originally designed to use plastic, tests have shown that UPM's barrier papers offer equivalent performance in terms of production speed, while reducing the waste associated with stretching plastic materials.
