Achieving sustainability goals - with pioneering process technologies.Efficient systems (not only) for the packaging industryThe packaging industry is increasingly faced with the task of reconciling ecological, economicand technological requirements with one another. This is where we come in withinnovative coating and calendering processes that prioritise resource conservation, efficiency and quality,efficiency and quality to the fore.The Pressurised Gravure System (PGS®) developed jointly with BASF - a next-generationnext-generation pressurised chamber doctor blade system - enables preciseprecise adjustment of the coating weight and achieves extremely uniform surfaceswith a return quantity close to zero. Our efficient multi-layer barrier coating systems allow the targeted optimisation of barrier properties - for both paper and paper-based products.for both paper and film-based packaging materials. Calender systems also offer considerable advantages in the production and further processing of filmsand support the fulfilment of increasingly important sustainability indicators.It is clear that sustainable solutions can only be realised in close cooperationrealised within the industry.

What makes packaging sustainable and how can we quantify this? Using a model study, we show how function-driven life cycle assessments with the inclusion of shelf life simulations enable a sustainability assessment with increased significance. The design of the packaging, shelf life, supply chain and consumer behaviour all come together to provide a comprehensive picture.

Packaging serves to protect our food. The EU's "Packaging and Packaging Waste Regulation" now stipulates that all plastic packaging must be either reusable or easily recyclable by 2030. For sausage packaging in particular, this means mono-PET or mono-PP as the packaging material. The latter material is not a problem for the shelf life of the sausage; oxygen barriers can be used here, but this does not apply to packaging made of pure PET. As food for thought, we would like to show an alternative way to ensure colour stability and freshness preservation for such products using protective cultures.
