The food packaging material is expected to provide optimum protective properties so that the product it encloses remains in satisfactory condition for its anticipated shelf life. The packaging technique, in conjunction with the choice of a packaging material endowed with appropriate gas and water barrier properties, aims to prevent destruction of food by microbial or insect attack. Packaging, and food packaging in particular, has been very eloquently described as “a complex, dynamic, scientific, artistic and controversial segment of business”[1]. The veracity of this definition can be easily certified since packaging is an exceptionally complicated process in which many company departments interact; it is “dynamic” because of its continuously changing character and “scientific” since further improvement of packaging is heavily dependent on scientific advances and innovations; of course, the scientific contribution is more than necessary for making the product more “appealing” to the consumer [2]. The increased consumer demand for high-quality, long-shelf-life, ready-toeat foods has initiated the development of mildly preserved products that keep their natural and fresh appearance as long as possible [3, 4]. Edible and biodegradable polymer films offer alternative packaging options advantageous to the synthetic “recalcitrant” packaging polymers because they do not contribute to the environmental pollution [5, 6]. Although edible films are not meant to replace synthetic packaging films entirely, they do have the potential to reduce substantially the environmental burden due to food packaging and to limit moisture, aroma, and lipid migration between food components [5, 7]. The potential of polysaccharides and proteins as edible films has long been recognized
