First, the polymers (biopolymer or bioplastics) are mixed with additives or fillers (plant extracts, bioactive compounds, essential oils, nanoparticles, agricultural waste, food waste, inorganic fillers) by melt extrusion or in the form of a solution. The melt extrusion composite is further processed by extrusion casting or blowing to develop packaging films. Polymer composite solution can be used to prepare solvent-casting films or to coat fruits by dip coating or spraying. (Figure created using Microsoft PowerPoint).
