A Review of Food Packaging Materials and Active Packaging System

Abstract

The purpose of this study is to give a brief review of food packaging materials and active packaging systems used in food processing. The purpose of food packaging is to make our lives easier. Food packaging that is effective serves a number of purposes. It functions as a container to hold and transport the food product, as well as a barrier to protect the food from outside contamination such as water, light, odors, bacteria, dust, and mechanical damage, keeping the food’s quality. The package may also include barriers to keep the product’s moisture content or gas composition consistent. Sensing is followed by adjustment of the environment in the package to improve the microbiological or biochemical quality of the food content. Active packaging systems, which are divided into adsorbing and releasing systems, can be used to extend the shelf life of processed goods. Active packaging is based on either the intrinsic features of the polymer used as a packaging material or the introduction (inclusion, entrapment) of certain chemicals into the polymer.
