Executive summary: our ambition


Introduction to safe food packaging design and compliance testing

You are encouraged to navigate through the different documents before using the different tools and databases. It is in particular required if you are not familar:
i) with EU Regulation of Food COntact Materials, ii) with polymer formulation and physico-chemistry and iii) with mass transfer modeling.

  • HELP CENTER for the SAFE FOOD PACKAGING PORTAL (click at the bottom of each image to see a menu)
Food-Packaging desorption simulation (multigeometries and FV formulation)

The physical assumptions are described in the introductive documents above and the principles of the mathematical methods are given along the tools.

  • 3D»1D approximations comprehensive geometrical modeling of complex food+packaging systems (with 3D and transparency).
Diffusant and polymer databases

Simulation tools require several properties (e.g. composition, transport properties and regulatory values (SML)), whose certain values are tabulated in our databases.
This section is dedicated to common properties and formulation of polymers. In addition, it provides different tools to navigate through the different nomenclatures.
Since nomenclatures are variables (either standard or proprietary), a unique search tool is pending.

Modeling of diffusion coefficients: D

This section is devoted to diffusion coefficients, which are required in simulation and decision tools. Please, note that available data are far from to be exhaustive for all polymers,
thermodynamical conditions and properties. Partition coefficients values (or Henry like coefficients) required for multilayers are in particular pending.

Integrated tools for decision making (under development)

The introductive section presents some new concepts to help the design of safer packaging materials. We propose here numerical tools in connection
with these concepts. Note that they use in real time and for thousands conditions the capabilities of previously mentioned simulation tools.
