An investigation was made of the dependence of the permeability of polyethylene packaging for the storage of granular sugar on the storage time. Increase in the permeability of the packaging is a consequence of the mechanical action of sugar particles. Standardised storage conditions ensure the retention of diffusional water vapour permeability through stacked packaging. A model is proposed for calculating the coefficient of water vapour permeability through packaging for a certain storage time.
