Finally, tightness of package bags based on TPS films was evaluated qualitatively. For this purpose, cherry tomatoes were packaged in developed bags and visual analysis was done during
storage. In Fig. 5 it can be observed that packaging bags were inflated respect to their initial condition. This observation is a consequence of gases production due to tomatoes respiration and
senescence mechanisms. On the other hand, gases accumulation within the bags is attributed to both good quality packages seal and high films barrier properties. Talc incorporation to TPS films
allowed a high accumulation of gases within bags associated to barrier properties improvement by particles presence.
