At present, most consumers turn more interested in food packaging that can degrade plastic packaging rather than from petrol to reduce environmental problems. This research has studied film production process thermoplastic starch digestion from (Thermoplastic starch, TPS), which comes from the tapioca because tapioca starch are cheap and easy to find, but there are also cons TPS is a film with low mechanical properties and absorption properties.High humidity causes, fungi, easily. Thus, the researcher therefore adjust the resistance properties of the fungus by selecting the apply Chitosan blended with TPS ratio using polyvinyl alcohol acetic vinyl takho Te P (VAc-co-VA) is a plastic recycle and make a film forming. It also has made improving water resistance properties of films by surface modified by coating polymer does not like water: Lae กอิมัลชัน prepared by the ideal method of evaporation by Emulsification with polyvinyl alcohol acetic vinyl takho Tequila (60% haidonlaisit) is an emulsifier Haifa.Yaoe. an analysis of the mechanical properties: the properties of resistance to pulling and physical properties, including the ability to steam and water resistance of the film from the trial showed that the composite Chitosan films TPS ratio of 5% Chitosan. There is strength and high tensile and resistant to water and water vapor. You can also resist fungus. Compared with the TPS film alone. In addition, the composite Chitosan films TPS through controlled surface coating that does not like water. I found that there is a clear trend of increase and there is a resistance to water and water vapor increases. Compared to films only that TPS may be to apply a film for wrappers.
