Moisture Management

Water condensation in packages can be reduced by use of micro (pin-hole size) or macro-perforated films. In heat shrink wrap film (eg. citrus), condensation is not a problem because the film is in intimate contact with the fruit and assumes the same temperature as the fruit. In case of loose wrapped produce (eg. cut flowers with in carton liner and fruit in a consumer pack), condensation can be reduced by using simple newspaper or slats in spun bonded polythene sachets. Anti fogging film and film with relatively high water permeability can be used (eg. cellophane and PVC).
Water absorbent is incorporated into packages to absorb and hold the free water
Eg. Silica gel in dry fruits packing.
