dc.description.abstract | [EN] The oxygen transmission rate (OTR) is a key parameter when selecting a sheet to make a thermoformed tray, as it influences the shelf life of packaged food. The OTR of a thermoformed tray depends on the distribution of the material's thickness over its walls. The goal of this study is to model the evolution of oxygen in the headspace of a thermoformed plastic tray considering the thickness distribution of its walls. PET/PE films with different thicknesses and a PET/PE/EVOH/PE structure with EVOH acting as a barrier layer were used for the thermoformed trays. The thickness of the thermoformed trays was measured at different points to determine the average thickness of the tray subsections. A model was built to predict the variation in the oxygen content inside the headspace over time. The results of the model were correlated with experimental data by regression analysis. The model can be used to perform a straightforward comparison of both different structures as well as the effect of the thickness of the layers that constitute the multilayer sheet. The model can also support decisions about the best multilayer for a particular tray design so as to achieve a specific product shelf-life. | es_ES |
