Paper packaging offers a number of advantages over its plastic counterparts: It has a high recycling rate, lower CO₂ emissions, and lower disposal costs. However, it cannot yet be sealed without adhesives or layers of plastic - a disadvantage for manufacturing and recycling processes. In the PAPURE project, four Fraunhofer institutes are developing a laser-based process that enables completely adhesive-free paper packaging.

Sustainable, recyclable packaging solutions are the future. However, processing the new recycled and mono-materials on existing packaging machines poses technical challenges.

When sealing or joining, these include increased reject rates due to leaky seal seams, increased tool wear with recycled materials, and potential restrictions on machine speed.

The 1st Kempten Sealing Forum will focus on the latest developments in sealing technologies for more sustainable packaging. Our expert Fabian Kayatz will present our practical solutions in the opening presentation.

Folding cartons are considered sustainable packaging solutions for numerous everyday products – whether breakfast cereals, electronic goods, medicines, or perfume. Made from paper and cardboard, folding cartons are resource-efficient to manufacture, biodegradable, and easy to recycle. However, environmentally friendly adhesives have been lacking for truly sustainable production. Researchers at the Fraunhofer Institute for Applied Polymer Research IAP are developing and testing bio-based adhesives for the industrial production of folding cartons in the Sustainable Gluing With Renewable Adhesives SUGRA project.
