Fraunhofer IVV in Germany and Hasselt University in Belgium are setting up a new European research project that looks at how melt flow behaviour during sealing affects the quality and leak tightness of flexible packages. The goal is to help
reduce the number of leaking packages by better understanding and optimising sealing settings such as seal time, temperature, pressure, cooling and bar surface geometry in relation to material properties like layer structure, viscosity and coating type.
The project will focus on flexible plastic films and coated papers that have the potential to comply with future PPWR requirements, especially for flowpack packaging used in vertical and horizontal form fill seal systems.
We would really value your input to help shape this project. This short form aims to clarify the scope and relevance for different stakeholders including raw material suppliers such as those producing polyolefins, paper and coating materials, packaging converters working with flexible or paper based materials, and end users from the food industry.
Your feedback will help us plan follow up discussions, find suitable partners and prepare a first project summary to share in November. We plan to submit the proposal in March 2026, and if approved, the project would start in early 2027 and run for about two years.
Please complete this form by 31 October so we can include your input in the first project outline.
