Characterization of recycled polyethylene terephthalate (rPET) – impact of proportion of virgin and recycled PET on mechanical strength
Résumé
Abstract. Polyethylene terephthalate (PET) is a standard plastic with the highest consumption in the food packaging industry. The large amount of bottles produced makes imperative the search for the recycled PET (rPET). However, the recycling procedure generates the modifications of the mechanical, thermal and optical properties from virgin PET to recycled one. In this study, Digital Image Correlation method associated to numerical simulation is used to identify the mechanical properties of the bottles. The effects of various recycled PET ratios on the mechanical properties of bottles are discussed.
