Predicting barrier failure in board and paper after converting

22 February 2018

For his thesis at Karlstad University in Sweden, Andreas Riedel investigated different methods to predict barrier failure in packaging board or paper after converting. The approach was to compare substrates before and after creasing/folding by applying different barrier tests.
A methodology to predict barrier failure after creasing and folding was proposed. Well defined creasing and folding geometries were used in combination with screening for cracks in the barrier layer, first by visual inspection in light microscopy and then by a standard grease resistance test. The samples that passed then screening tests could then be analyzed using more exact but also more time consuming methods.
