In this paper, a numerical and experimental study was undertaken to investigate the mechanical behaviour of a polypropylene bottle used to store cosmetic products when loaded under columnar crush conditions. The effect of amyl acetate concentration and temperature of aging on the mechanical properties of the bottles was experimentally evaluated. Analytical models describing the influence of the amyl...
In this paper, we present the methodology and the results obtained by the gravimetric and the FTIR methods to study the sorption of amyl acetate in polypropylene packaging. The influence of the concentration of amyl acetate and the temperature of aging on the sorption is discussed. A non-Fickian model is used to determine the diffusion coefficient and the surface mass transfer coefficient and their...
