Properties of pullulan-based blend films as affected by alginate content and relative humidity

► Mechanical properties of pullulan–alginate films are affected by polymer blend ratio and water activity. ► Glass transition deceases as water activity increases. ► We use FTIR to probe different water molecules exist in pullulan–alginate films as water activity changes. Pullulan–sodium alginate bl...
