    Resumen

    Banana fruit production is a dynamic economical sector in Colombia. However during the agricultural labor, banana plants need to be tied to each other using strings. This practice helps to support the fruit weight before the harvesting. Polypropylene strings are used in this application. This practice is becoming an environmental issue in cultivation areas, and it is necessary to identify biodegradable alternative materials. In this study, samples of polypropylene, polypropylene/starch blend and a commercial biopolymer, referred to as Mater-Bi and PP/ Mater-Bi, were analyzed. The stability of these materials in tropical regions such as Uraba (Colombia) was evaluated. The changes in the material structure and properties were analyzed by differential scanning calorimetry (DSC) and FTIR spectroscopy. Slight variations of mechanical and physical behavior of exposed samples were observed. Even though starch and biopolymer reduced the tensile behavior of polypropylene blends, these blends can be used for this application.
