This document discusses edible packaging as an environmentally friendly alternative to traditional plastic packaging. It provides an introduction to edible packaging, explaining why it is needed due to the large amount of non-biodegradable plastic waste. Edible packaging is defined as a thin edible coating or film that can be consumed as part of the food. Various biopolymers like proteins, polysaccharides, and lipids can be used to form these edible coatings and films. While edible packaging has benefits like reducing waste and adding nutrition, it also faces challenges for wide commercial use like high costs and poor barrier properties compared to plastic.
