Research into edible films and coatings began in the 1990s, focusing on polysaccharide and protein-based materials to extend the shelf life of produce. These innovative coatings provide a protective barrier against moisture and microbial growth, enhancing food preservation. The development of edible coatings represents a significant advancement in food technology, addressing concerns about food waste and sustainability in the agricultural sector.

The development of edible films and coatings for food preservation in 1990 inspired a wave of eco-poetry that envisioned sustainable futures. Poets began to explore themes of harmony with nature and the importance of reducing waste, reflecting contemporary environmental concerns.
