The web-based barrier calculator of plastics and packaging institute Norner has proven to become an important tool for the packaging industry. And since the new WVTR (Water Vapor Transmission Rate) functionality was added to the calculator, hundreds of new users now make their calculations every week to simulate their packaging barrier performance at different conditions.

The calculator is based on a calibrated simulation model developed by Norner. This simulation model estimates the OTR (Oxygen Transmission Rate) and WVTR of plastics packaging material like PP, PE, PET, PA and EVOH. The main objective is to enable calculation of permeability for customer specific packages and geometries. The model has been verified by tests done on real packaging samples.
