Free OTR and WVTR calculator

Norner offers free use of OTR and WVTR Barrier Calculator. 

You can access via the below icons.

  • This simulation models estimates the oxygen and water transmission rate of various plastics packaging material like PP, PE, PET, PA and EVOH.
  • Barrier properties of coextruded, co-injection multilayer and in-mould-label solutions can be studied and evaluated.
  • The combination of geometrical options, permeability properties and environmental conditions provides an useful tool for design and development.
  • The OTR and WVTR values are calculated separately.

OTR Calculator

WVTR Calculator

Calculation steps

  1. Define geometry parameters (e.g length, radius, height).
  2. Choose materials (define layer material and thickness).
  3. Define environmental conditions (temperature, humidity).
  4. Push calculate.
  5. View and evaluate calculation results.

We offer:

  • These models focuses on OTR and WVTR simulations of multilayer barrier film, multilayer containers and barrier in-mould label containers.
  • Norner AS is involved in several development projects involving other barrier technologies and has deep knowledge within this field.
