Abstract Food packaging materials compounded with antimicrobial additives
can substantially diminish the incidence of foodborne diseases. Here, poly(L-lactic acid) (PLA) films containing sodium metabisulfite (NaM) were produced by
melt extrusion as an attempt to develop a new biodegradable material with antimicrobial properties for packaging. Life cycle assessment (LCA) simulations
revealed that the environmental footprints of the PLA film did not change upon
NaM addition, and that NaM is more eco-friendly than silver nanoparticles.
The PLA/NaM films with NaM content varying from 0.5 to 5.0 wt.% were characterized by differential scanning calorimetry (DSC), thermogravimetric analysis
(TGA), and optical and mechanical properties determinations.… More >
