Investigation of mechanical properties the polylactide in function its degradation rate

Abstract

Polylactide is compostable and biodegradable thermoplastic polymer. It is made from renewable sources like tapioca roots, corn starch or sugar cane. Polylactide can be used as a material in food and packaging industries. According to manufacturer’s instruction biodegradable bioplastics can be used for disposables applications such as cups, cosmetic packaging etc. In some cases, the type of stored substances can affected on container stability. The aim of the study was an investigation of mechanical properties of PLA depend on its degradation rate. Obtained results show degradation process of injection moulded PLA in simulated physiological fluids. Results of the study can be helpful to prediction of the behaviour of products manufactured with biodegradable polylactide.
