3.3.1. Tensile and flexural properties
The stress–strain curves of the neat and blended samples are
displayed in Fig. 4. It should be noted that BioPE and PTT/BioPE (20/
80) wt.% blend each had an elongation greater than 50% where they
reached strain values of 630% and80% elongation, respectively. The
addition of BioPE reduced the tensile strength and modulus and the
elongation at break. Similar trends were seen with other polymer
blends containing LLDPE. When LLDPE was blended with poly(lactic
acid), PLA, [34,35] and polypropylene (PP), [36] it was observed that
