Conclusion and future trends

Bio-based polymers are rapidly emerging as sustainable alternatives to conventional synthetic and petroleum-based materials, being highly desired in many diverse areas for high-value applications. These materials could indeed be an answer to society regarding filling some lacks in the most diverse sectors, such as food packaging industry. It is expected that in the future, the innovation on the use of lignocellulosic materials in bio-based packaging will range from the extraction and purification of the lignocellulosic materials to the type of application where these materials are used (i.e. active and intelligent packaging).
