Norner offers OTR, WVTR and CO2TR barrier calculators

Barrier calculator

Norner offers advanced OTR, WVTR and CO2TR barrier calculators with several features.

These calculators are being continuously improved with new features. The calculators are available on a separate web platform in simpler free and an advanced paid version. 

Norner Barrier Calculator


Geometry - film, cup, bottle and cuboid

Barrier calculations can be carried out on different geometries; film, cup, bottle and cuboid. This enables you to simulate your target package design. The calculating models gives you estimates of the O2 (oxygen), Water Vapour and CO2 Transmission Rate of various plastics packaging material like PP, PE, PET, PA and EVOH.

These barrier properties of coextruded, co-injection multilayer and in-mould-label solutions can be studied and evaluated by adding layers of the geometry or IML.

The combination of geometrical options, permeability properties and environmental conditions provides a useful tool for design and development.

  • You can now add a sequence of conditions as you experience in the logistic chain with different temperatures and humidity.

Calculating steps

  • Define packaging type and geometry parameters (e.g length, radius, height, width)
  • Define layers, choose materials and thickness
  • Add as many layers as needed
  • Define environmental conditions (temperature, humidity)
  • Alternatively, add more conditions in a sequence
  • Push “calculate” and view the calculation results
