This thesis to study the mechanical properties of the film chain a little dog additional extraction of glycerol. 25% concentration by weight of the dry weight per gram of a little dog by forming a film to test the mechanical properties. Found that little dog network film mixed glycerol onsamarot good. Film chain a little dog mixed glycerol hired, although high levels of nakhon will result in making the film thickness increases. While the tensile strength and elongation percentage of film increase significantly. In addition, the film chain a little dog mixed glycerol concentration onkhwam 25 percent by weight of the dry weight per gram of a dog. Result, no water absorption rate compared with Chitosan film contains glycerol.
