The thickness of active films decreased significantly in comparison
with the control (p < 0.01). This significant diminutionwas
more noticeable at the highest concentration of Proallium®. This
observation was related to a higher fluidity of the PLA and Proallium
® mixtures, which had a tendency of melting to generate a
non-homogeneous thickness profile along the width of the films
(transverse machine direction).
