| Abstract: | This review summarizes recent research activities devoted to the preparation of films from modified hemicelluloses. Potential applications of these novel films are identified in packaging and edible coatings in foodstuffs. Special emphasis is put forward to the comparison of three main properties, oxygen permeability, water vapor permeability and mechanic properties, between the modified hemicellulose films and traditional polymeric films. Modified hemicellulose films are renewable and biodegradable with comparable barrier properties with the traditional polymer films, making them new candidates in environmental materials. |
