at industrial scale. Films and coatings with improved physicochemical properties can be obtained by blending different biopolymers, or biopolymers with nanoparticles, antioxidant, or antimicrobial compounds, among others. Most researchers have focused on developing films and coatings at laboratory scale, particularly using the casting and dip casting methodologies. It is necessary to regard other approaches such as thermo-pressing molding, extrusion, blown extrusion, reactive extrusion, and spraying, aiming films and coatings production at industrial scale. The use of alternative approaches such as electrospinning, electrospun, ionic gelation, layer-by-layer, plasma, and self-assembly could produce new biopolymer architectures with a positive impact on the physicochemical properties of films and coatings. Finally, the toxicity and migration of macromolecules and additives in films and coatings must be carefully investigated before the application of these materials by the food packaging industry.
