Sustainable packaging - Why we do what we do
is a research organization developing innovative and environmentally friendly papers for food and non-food packaging. We are an interdisciplinary team of scientists and engineers who contribute to reducing packaging waste with smart and sustainable packaging solutions.
Our partners
Less material, full performance - safely recyclable
We aim to achieve an optimal balance between low material use and performance, on the one hand, and recyclability and food, safety on the other.
Comprehensive support for sustainable packaging
We support our customers throughout the entire development and industrialization process for sustainable packaging transformation, from material selection to process optimization.
FAQs
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 applies to a specific part of packaging, namely single-use plastics.
First of all, it must be emphasized that the PPWR does not replace the SUPD, but adds to it. The SUPD remains a more specific rule ("lex specialis") and takes precedence within its scope of application (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 is therefore directly applicable in all EU member states (without additional national laws or regulations).
The PPWR clearly focuses on recyclability on an industrial scale, on consistent design-for-recycling and on conformity and documentation requirements. The criteria for the recyclability of a barrier paper are currently being developed within the framework 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 prove recyclability.
We will soon also be offering coatings with a recycled content for our product - without compromising the barrier performance.
Finally, it should be mentioned that the future disposal costs (EPR) of packaging are determined directly by the recyclability according to PPWR. For our customers, this means that the total costs for packaging with good industrial recyclability, such as our barrier papers, will fall, while those for packaging with poor recyclability will rise dramatically.
Our 20-strong team consists of scientists, engineers and technicians. We have been working intensively on the development of barrier papers for a wide range of packaging applications since 2020. 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.
We have mapped large parts of the subsequent process chain of our products in our laboratories and operate a recycling laboratory (tests according to CEPI, PTS, Aticelca), a packaging laboratory (with an HFFS machine) and a shelf life laboratory. In the delfort Printing Group, the delfort Group has bundled concentrated knowledge of printing inks and printing technologies, which we at DELSCI can access directly.
Our application engineers have accompanied a large number of proofing and packaging tests, optimized the processes together with the customers and gained valuable experience in the process. We therefore know the most important relationships between our materials and our customers' products and processes. We use this knowledge and experience to support our customers in the challenging transformation of their packaging.
