Gratis beregning av Oksygen permeabilitet (OTR) og Water Vapor Transmission Rate (WVTR)
Norner is an independent, industrial Polymer Institute for the plastics and material industries.
- We offer free use of our OTR and WVTR calculators.
- This simulation models estimates the oxygen and water transmission rate of plastics packaging material like PP, PET and EVOH.
- Barrier properties of 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 when working with the design, development and application of plastic packaging.
- The OTR and WVTR values are calculated separately.
- Define geometry parameters (e.g length, radius, height).
- Choose materials (define layer material and thickness).
- Define environmental conditions (temperature, humidity).
- Push calculate.
- View and evaluate calculation results.
- 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.
