Recycled PET Material with Mechanical Properties Equivalent to Virgin PET

A nanocomposite made up of vPET and RPET from post-consumer bottle plastic, with enhanced mechanical properties, similar to a 100% vPET

Background

Polyethylene terephthalate (PET) is the most widely recycled plastic in the world. As with virgin PET (vPET), recycled PET (RPET) can be used to make a variety of new products, generally blended in a certain ratio with vPET, depending on the required application.

Despite the technical ease with which it can be recycled, RPET has poor mechanical properties due to deterioration caused by the polymer thermal and processing cycles, allowing a maximum use of 30% RPET in the blend for the manufacture of certain types of packaging. This, coupled with the competitive PET market, which drives innovation and efficiency keeping costs low, makes it difficult for RPET to compete with vPET.
