摘要

In this study, we investigated the effect of fouling on the dissolved oxygen and carbon dioxide permeation in water through maximum-crystallized poly(lactic acid) (PLA) films by using proton nuclear magnetic resonance, attenuated total reflection-Fourier transform infrared spectroscopy, wide-angle X-ray diffraction, and ultraviolet-visible spectroscopy, contact angle, water content ratio, and dissolved gas permeation. Fouling means the adhesion of contents on a container's internal surface, where content adhesion can directly influence the barrier property of the container. Glucose, a beverage ingredient, was used as a foulant. The permeation of dissolved gases in amorphous PLA film, maximum-crystallized PLA film, and fouled maximum-crystallized PLA film was determined. The decreased interstices in the polymer chains during crystallization resulted in the inhibition of the diffusion and decrease in the permeability coefficient of the gases. Moreover, the slope of the permeability coefficient for carbon dioxide in the Arrhenius plot was found smaller than that of oxygen's. This result indicated that the gas barrier property of dissolved carbon dioxide was considerably influenced by solubility and readily decreases during glucose fouling.
