Evaluation of Polymeric Films Based on Starch and Antimicrobial Compounds as an Alternative to Replace Food Wrap

Abstract

One of the macromolecules most used as a replacement alternative for some conventional packaging materials is starch. This is due not only to its high bioavailability and economy, but also to its positive environmental impact. However, this material presents important physical-mechanical limitations, 
such as: high permeability to water vapor, rigidity, fragility, hygroscopicity and tendency to retrograde. Additionally, the incorporation of antimicrobial 
compounds in the polymer matrix enhances the use of these films, and the addition of plasticizers and reinforcing materials improves their mechanical 
properties so that they can increasingly compete with synthetic polymers.

This review article presents information on films based on starch obtained from tubers, and the effect of incorporating natural antimicrobial compounds present in some essential oils.
