Abstract
The effects of alginate extracting conditions from sea tangle and the effects of film preparation conditions on the physical properties of the alginate film were investigated by measuring ester compounds permeability. The higher concentration of sodium carbonate solution as extracting solvent made the higher ethyl acetate permeability of alginate film, but extracting time showed little efficacy of alginate film permeability. The higher concentration of sorbitol as a plasticizer showed higher ethyl acetate permeability of alginate film, Adding various plasticizers, the ethyl acetate permeability of algiante films was increased in order as follow : sorbitol, glycerol and polyethylene glycol. Ester compounds haying the lower molecular weight showed the higher permeability. And the higher temperature made the ethyl acetate permeability of algiante film to be high.
