Materials and packaging materials may come into contact with to food, medicines or cosmetics or othermore they are used in industrial environments (medical, buildings). LNE can provide you with its expertise and skills to qualify or assess the performance of your products and materials in the field of gas or water vapour transfer phenomena.
Among the proposed characterisations:
To satisfy these testing needs, the LNE Laboratory features the following set of instruments:
