The influence of fibrillation on the oxygen barrier properties of films from microfibrillated cellulose

摘要

The potential of microfibrillated cellulose (MFC) films as oxygen barrier has been investigated in several studies before. However, no study clearly shows the minimum degree of fibrillation, which is required to reach this barrier property. In the case where a range of different fibrillation grades of the same material has been evaluated, it was seen that increased fibrillation brought no significant observed changes in oxygen barrier properties.
