Green‐based active packaging: Opportunities beyond COVID‐19, food applications, and perspectives in circular economy—A brief review

The development of biodegradable packaging, based on agro‐industrial plant products and by‐products, can transform waste into products with high added value and reduce the use of conventional nonrenewable packaging. Green‐based active packaging has a variety of compounds such as antimicrobials, antioxidants, aromatics, among others. These compounds interact with packaged products to improve food quality and safety and favor the migration of bioactive compounds from the polymeric matrix to food. The interest in the potential hygienic–sanitary benefit of these packages has been intensified during the COVID‐19 pandemic, which made the population more aware of the relevant role of packaging for protection and conservation of food. It is estimated that the pandemic scenario expanded food packaging market due to shift in eating habits and an increase in online purchases. The triad health, sustainability, and circular economy is a trend in the development of packaging. It is necessary to minimize the consumption of natural resources, reduce the use of energy, avoid the generation of waste, and emphasize the creation of social and environmental values. These ideas underpin the transition from the emphasis on the more subjective discourse to the emphasis on the more practical method of thinking about the logic of production and use of sustainable packaging. Presently, we briefly review some trends and economic issues related to biodegradable materials for food packaging; the development and application of bio‐based active films; some opportunities beyond COVID‐19 for food packaging segment; and perspectives in circular economy.
