Maria RAPA, ELENA GROSU, Zina VULUGA, ANDREIANA SCHEAU, CRISTIAN STANESCU Biodegradable Blend Based on LDPE/Starch with Agriculture Applications


Abstract:
A biodegradable blend based on low-density polyethylene (LDPE) and 36 % starch that can be used for horticultural application was studied. The mechanical properties and the processing by molding injection were also studied. It is found that the starch helps to increase surface area on which the microorganism can attack the polymer matrix. The increase in the carboxyl index, which indicates the concentration of carboxyl blend, with time, also indicates the progress of biodegradation. Although this type of blend is not completely biodegradable it is preferred to those completely biodegradable which are expensive and with many processing problems. Keywords: biodegradation, starch, polyethylene, blend, application
