DELSCI - We give paper superpowers

Barrier papers are special papers with functional surface coatings. At delfort, they consist of at least 80% FSC-certified cellulose fibers and are therefore easily recyclable in the existing waste paper cycle. These base papers contain a special mix of fibers and fillers for optimal runnability on high-speed processing and packaging machines. The papers are usually highly calendered and prepared for surface coatings. These ultra-thin surface layers (layer thickness of a few micrometers) guarantee the necessary barriers (e.g. against grease, water vapor, oxygen, aroma, mineral oils, etc.) and heat sealability for use in flexible packaging for food and non-food items. As barrier papers can still be recycled in the normal waste paper cycle due to the low proportion of coatings and also have a good ecological footprint, they are a sustainable alternative to plastic and composite packaging for many applications.

The PPWR applies to all packaging in the EU, regardless of the material, while the SUPD only affects a specific type of packaging, namely single-use plastics.
Firstly, it must be emphasized that the PPWR does not replace the SUPD, but rather supplements it. The SUPD remains in place as a more specific rule ("lex specialis") and takes precedence within its scope (single-use plastics). The PPWR has been in force since February 2025 and will be binding from August 2026. The PPWR is a regulation (the SUPD is a directive), which means it is directly applicable in all EU member states (without additional national laws or regulations).
The PPWR clearly focuses on recyclability on an industrial scale, consistent design for recycling, and conformity and documentation requirements. The criteria for the recyclability of barrier paper are currently being developed in the context of so-called design for recycling tables. These tables form the binding basis for the assessment. In addition, the CEPI recycling test protocol can be used to verify recyclability.
We will soon be offering coatings with recycled content for our product – without compromising barrier performance.
Finally, it should be mentioned that the future end-of-life costs (EPR) of packaging will be determined directly by recyclability according to PPWR. For our customers, this means that the total costs for industrially recyclable packaging such as our barrier papers will decrease, while those for poorly recyclable packaging will increase dramatically.

Our team of 20 consists of scientists, engineers, and technicians. Since 2020, we have been working intensively on the development of barrier papers for a wide range of packaging applications. We have collected and analyzed a large amount of chemical and physical data on our products as well as process data from the processing of barrier papers (printing, packaging, transport, shelf life) in databases.
In our laboratories, we have mapped large parts of the downstream process chain for our products and operate a recycling laboratory (tests according to CEPI, PTS, Aticelca), a packaging laboratory (with an HFFS machine), and a shelf life laboratory. The delfort Group has pooled its expertise in printing inks and printing technologies in the delfort Printing Group, which we at DELSCI can access directly.
Our application engineers have supervised a large number of proofing and packaging trials, optimized processes together with customers, and gained valuable experience in the process. We are therefore aware of the most important relationships between our materials and our customers' products and processes. With this knowledge and experience, we support our customers in the challenging transformation of their packaging.
