This packaging is intended to maintain the properties of food for a longer period without the need to add chemical additives. This is due to the biodegradable film containing antimicrobial and antioxidant compounds from mango leaf extract that have been tested in vitro, while at the same time offering a more powerful ultraviolet light filter, that also delays food spoilage. These tests looked at antimicrobial performance against two food pathogens: Staphylococcus aureus and Escherichia coli. The researchers compared two different techniques for obtaining the packaging.
