| English abstract | Conventional packaging based on petroleum have been used in a wide variety of application due to its durability, mechanical and barrier properties, ease processing and low cost. However, in recent years there is an increasing concern due to environmental problems because such packaging takes hundreds of years to decompose. Sustainable packaging from renewable resources has been widely studied for replacement of synthetic polymers. Some drawbacks of biodegradable plastics still limit their commercial application, such as poor mechanical and water barrier properties, which make them difficult to use in food packaging. Different strategies has been used to overcome these limitations, such as blends and multilayer films, adding nanoparticles and active compounds, modifying the structure of the films using plasma and UV techniques, among others |
