Light transmittance
of films determined at 660 nm (T660) and 280 nm (T280)
indicating film transparency and UV light screening properties of
the film, respectively, were also shown in Table 1. The results
indicated that PLA film was very transparent with high T660 of
90.7%, on the contrary, PBAT film was not transparent with low T660
of 7.6%. The transparency of PLA film decreased by blending with
PBAT, which decreased linearly with increase in the blending ratio
of PBAT up to 0.4 g (PLA90/PBAT10).
