Heidelberg and Solenis collaborate to establish a method for applying protective coatings to paper packaging materials.
In the realm of packaging, sustainability is becoming increasingly important. Several key players in the industry are making significant strides towards a greener future.
Heidelberg and Solenis have joined forces to develop a process for the industrial, partial, and cost-effective application of barrier coatings to paper packaging. This collaboration aims to address one of the main challenges in sustainable packaging - finding materials that act as a barrier to water, water vapour, hot and cold liquids, oils, and fats, while also fulfilling sustainability requirements.
Lecta, a leading name in the paper industry, has introduced its Linerset FP barrier base paper. This innovative product is suitable for a wide range of applications, including food and industrial packaging. Available in various grammages (40, 45, 50, 56, and 78 g/m2), the paper offers a strong translucent alternative for bags, pouches, and wrapping applications. Lecta's Linerset FP barrier base paper is also a versatile choice for flexible packaging.
Another significant development comes from Smart Planet Technologies, which has released a biopolymer version of its EarthCoating barrier coating. This coating combines a biobased PLA resin with a specialized mineral blend to produce both compostable and recyclable paper cups. The mineral content in the coating enables it to be removed in the same way as clay fillers, which are already used in paperboard and designed for removal during the recycling process.
Top brands are also progressing on packaging sustainability. Graphic Packaging, for instance, has achieved child safety certification for its CleanClose™ cardboard packaging, received four gold awards at the AmeriStar Awards 2025, and advanced recycling efforts for paper cups as part of their Better by 2030 program. Meanwhile, MM Group has reduced CO2 emissions to about half the levels of 2019 through decarbonization investments in 2024.
As we look towards the future, it's clear that the packaging industry is committed to sustainability. Information is available on how global packaging sustainability regulation will look like in 2025, with a guide provided for the Packaging and Packaging Waste Regulation. The expected update to this regulation in 2025 promises to further drive the industry towards more sustainable practices.
In supermarkets, the key to increasing the use of reusable packaging is also a topic of discussion. The benefits of reusable packaging, such as reduced waste and lower carbon emissions, make it an attractive solution for the future of packaging.
As these developments show, the packaging industry is moving towards a more sustainable future. With innovative products like Lecta's Linerset FP barrier base paper and Smart Planet Technologies' biopolymer EarthCoating, the industry is well-equipped to meet the challenges of sustainability and continue to provide high-quality packaging solutions.
