biopolymer fulfill the environmental concerns but they show limitations in term of performance like thermal resistance, barrier and mechanical properties, associated with the cross. Then, this kind of packaging materials needs more reserch, more added value like the introduction of smart intelligent molecules (which is the nanoterchnology field) able to give information about the properties of the food inside the package (quality, shelf-life,microbiological safety) and nutritional values. it is necessary to make researches on the kind of material to enhance barrier properties, to ensure food properties, to ensure food properties integrity, to incorporate labelling, to give to the consumer the possibilty to have more detailed product information than current system
