Permeability of materials, packaging and industrial products

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.

Proposed services

Among the proposed characterisations:

  • Barrier properties - gas permeability on plastic/aluminium materials and single or multi-layer packaging:
    • to water vapour
    • to oxygen
    • to carbon dioxide
  • Adapted temperature (ambient, low or high temperature)
  • CO2 losses on capped sparkling or still wine bottles (standardised test)
  • Technical expertise in the design of your packaging or finished products.

Resources available

To satisfy these testing needs, the LNE Laboratory features the following set of instruments:
