The facillities for Kimchi preservation were investigated in order to develop the taste, flavor and commercial quality of Kimchi during fermentation. Four kinds of facillities used for this experiment were PP(Polypropylene). PSC(Polypropylene+ceramic)and PPP was selected newly and laminated of three layers with PETG (Polyester G), PS (Polystyrene) and PETG. The change of total number of lactic acid Bacteria, pH, acidity, color, gas contents and free internal volume of package were measured for the Kimchi packaged by 4 facillities during 6 days fermentation at 15$^{\circ}C$. The total No. of lactic acid Bacteria within the Kimchi in the PPP facillity was more and remained longer time (120 hrs.) than other Kimchi in the PP, PS and PPC facillities. Also the pH of all Kimchi were decreased to pH 4 within 72 hrs. and the pH of Kimchi in the PPP facillity was kept as pH 4 for 120 hrs., so that was shown to be decreased more dully than others. In case of fimchi in the PPP facillity, the color was retained better, CO$_2$ contents was lower similar to PPC facillity, and swelling degree of free internal volume was higher than others. By the sensory evaluation, the Kimchi in the PPP facillity represented as better than others for color, flavor, texture and total preferences until 48 hrs. fermentation. And the PPP facillity is transparent, so these will be selected and confirmed more easily, also PPP facillity is so hard to endure the swelling pressure of internal gas. Therefore it is thought that the PPP facillity used as Kimchi package will be desirable for better taste, flavor, and commercial quality.
