The buildup as consciousness of people environmental protection more and more realize plastic pack use undeserved place to cause pollution of “ white ” , some material food pack the gas with easy harmful generation and peculiar smell, still have certain harm effect to human body, the country such as the United States, Japan developed a lot of edible to pack in succession nowadays film and but the film of biology degradation.

In recent years, a lot of domestic and international food researcher put research on the edibility film that pack mainly gradually, the edibility that developed a lot of different functions packs film, if soja albumen edibility packs film, carapace,get together candy edibility is amylaceous and the film that pack, protein, fatty acid, compound model container of the film of protein of water of the edibility film that pack, La, edibility wrapping paper that is raw material with residue from bean after making soya-bean milk, edibility, maize gluten meal packs film (paper, besmear pledges) , bug film.

Current, edibility packs the main trend that is development of new science and technology of world food industry, it already involved extensive applied field, bag garment waits garment of paper of candle of casing, fruit, icing, polished glutinous rice, ice and pill a moment. Because edibility packs functional diversity, harmless environment, draw materials is convenient, can offer edible, because this developed country develops development unexpectedly, new product, new technology is ceaseless emerge in large numbers, development perspective is wide. With day inch, develop energetically new-style, easily the treatment, material that reclaim and increases environmental protection, wash out backward material. The quality that should consider to pack not only, function, cost, should consider to be machined from material expect more, use, the effect that the environment lists in deserted whole process, with making material, the sources of energy gets utmost use, fall the influence that packs an environment nadir or 0 pollution. Muti_function edibility container has tendency of two kinds of research at present: It is amylaceous protein material, 2 it is cellulose protein material.
