New alliance between Heidelberg and Solenis advances barrier coating application technique for cardboard packaging
In the world of flexible packaging, Lecta has made a significant stride with the introduction of its Linerset FP barrier base paper. Designed specifically for converters and printers, this innovative article is suitable for a wide range of applications, including food and industrial packaging, and is available in various grammages (40, 45, 50, 56, and 78 g/m²).
However, a recent guide did not mention Lecta's release of the Linerset FP barrier base paper, nor did it discuss its strong translucent alternative for bags, pouches, and wrapping applications.
Meanwhile, Heidelberg and Solenis have joined forces in a collaboration that aims to revolutionise the flexographic web printing process. The guide did not provide details about this collaboration, but it is known that Heidelberg has integrated Solenis' technology into its process with the Boardmaster. The collaboration has also focused on barrier coatings, but the specifics of this aspect were not covered in the guide.
The main challenge of this collaboration was finding suitable materials that act as a barrier to water, water vapour, hot and cold liquids, oils, and fats, while also fulfilling sustainability requirements. The barriers are transferred to the paper web with precise registration only at necessary points during the ongoing process.
It's worth noting that the Packaging and Packaging Waste Regulation in 2025 is the subject of an ultimate guide. This guide does not discuss the details of the collaboration between Heidelberg and Solenis, nor does it mention the presentation of their process at Fachpack 2025 in Nuremberg.
Smart Planet Technologies has also entered the scene with the release of a biopolymer version of its EarthCoating barrier coating. This innovative coating combines a biobased PLA resin with a 'specialized mineral blend' to produce both compostable and recyclable paper cups. The guide did not discuss this release or the combination's potential for paper containers at Fachpack 2025 in Nuremberg, where the company Emsland Group is presenting the use of biopolymer EarthCoating protective coatings for paper containers.
A separate article discusses the progress of top brands on packaging sustainability, while another guide offers insights into increasing the use of reusable packaging in supermarkets.
In the broader context, a comprehensive article provides information about global packaging sustainability regulation in 2025. This article serves as a valuable resource for those seeking to stay informed about the evolving landscape of sustainable packaging practices.
