It is necessary to recognize philosophical and scientific depth, contained in traditional culture in a correct fashion, in order to succeed and develop our excellent traditional culture. Some studies on storage, circulation, and package design of traditional food will multiple the added value of traditional culture. So this research was carried out for making packing cases of kinds of Korean dried confectionery using Hanji by traditional manufacturing method, Hanji textile, charcoal Hanji and jade Hanji, and for developing environmental-friendly Korean dried confectionery package as more luxurious packaging papers by putting an exterior design on the surface. The results measured physical properties, air permeability and anti-mold activity of Hanji, and designing Korean dried confectionery are as follows. The physical properties and air permeability used to manufacture Korean dried confectionery package, turned out to be no affection to the food packaging Hanji. In order to avoid the monotonousness of Korean dried confectionery package, it was designed with Hanji textile together with elegant traditional pattern. It is estimated to increase the value of Korean dried food and to make the anti-mold activity of Hanji added charcoal and jade effective. In conclusion, by developing individual properties of traditional food and proper packaging paper as well as packaging design according to circulating situation, it is considered that the taste and the fancy can be maximized. After all, by applying excellent traits contained in our race's culture, it is possible to develop the package cases into competitive ones. And it would be able to increase utilization of Hanji. Namely, production of high quality traditional food package with Hanji is expected for new valuable industry of Hanji.

Most of printing paper market today have been occupied by western paper and some machine-made Hanji used don't show the characteristic advantages for traditional hand-made Hanji. Although hand-made Hanji has an aesthetic and qualitative value, it has limited uses because of poor printability as printing paper. Unlike western paper, conventional Hanji cannot be used as Printing paper because it is impossible to make the clear formation of printed dot and to develop a high level of sizing and picking problem occurs during printing. Improvements of physical and optical properties such as roughness, smoothness, air permeability, contact angle, opacity, and paper gloss as well as sizing level were accomplished through internal and surface sizing and calendering, which made the paper better suited for printing and decreased problems during printing.

The optimum dewaxing ratio in dewaxing treatment by the heat and pressure method was investigated by considering aging stability of dewaxed Hanji. Commercial Hanji was coated with beeswax and thermally aged at $150^{\circ}C$ for 24 hours. Then it was dewaxed using the laboratory sheet press equipped with hot plates on both top and bottom sides. Dewaxing ratio was controlled by pressing temperature and time. Four type of dewaxed Hanji samples with different dewaxing ratio were prepared and thermally aged at $150^{\circ}C$. Then the aging stability of dewaxed Hanji samples was evaluated in terms of optical and strength properties. It was found that the aging stability of dewaxed Hanji was superior with higher dewaxing ratio. The result concluded that, in the aspect of aging stability, the coated beeswax in beeswax-treated Hanji shall be completely removed if the coated wax would be dewaxed.

The various kinds of Hanji were manufactured by a few craftsmen at several provinces in Korea. It is very difficult to distinguish each others by its name so-called, Hanji, traditional Hanji, improved Hanji, mechanical Hanji and so on because the manufacturing process, raw materials and characteristics of Hanji are very different from each others. In this research, the functional properties of Hanji depending on the manufacturing process were evaluated and compared each others. The properties of Hanji was greatly changed according to grammage, lye and dochim. The higher the grammage resulted in the lower the pore size and the air permeability. Hanji made by NaOH and CaO showed relatively high brightness than that made by traditional lye(Yuokgae). Hanji treated with dochim can absorb high frequency(2,000 Hz) sound more effectively.

Jeonji technique was widely used in general Hanji handicraft including Jihwa handicraft. But the technique itself has not been passed on. By contrast, Jiseung technique and Jiho technique have been passed on and continuously developed. And although the Huji technique has not been transmitted, it should be vigorously used as a technique of producing the frame in order to revive the authenticity of traditional Hanji handicraft. Jumchi technique, a method of using water to connect between layers, is an effective technique of diversely expressing the feel of materials of Hanji craftworks. Modern Hanji handicraft has used the characteristics of paper and paperboard diversely produced nowadays as much as possible, which shows that it is more likely to develop as handicraft.

This study was carried out to investigate the characteristics of the Hanji which had been used for movable types printing volumes of the Joseon Dynasty. A total 29 volumes which had printed with metal and wooden movable types, were examined on the physical properties, fiber morphology, and color reactions. The grammage of all of the Hanji which had been used for movable types printing volumes were $13.10-51.65g/m^2$ and on the average was $25g/m^2$. The apparent density of the Hanji was $0.23-1.65g/cm^3$ and on the average was $0.4g/cm^3$. In almost all movable types printing volumes, the Hanji had undergone Dochim which is a processing of printability improvement. Through the examination on fiber morphology and color reactions, Hanji was investigated into that all of those were made from paper mulberry bast fiber.

The purpose of this study was to design wedding dress by using Korean paper(Hanji). The Korean paper showed the good(excellent) properties of durability, softness, and tensile strength was 3.7Kg, tear index was 6 mN$.$$m_2$/g and folding numbers was 466. The appreance of Hanji was widely varied by blending(mixing) with other materials and various effects, pleating, crumpling, twisting and so on were achieved. The dress silhouette and form transformation of Hanji was very easy. Detailed points those are frill, pleats, gather, bow, paper casting, pin tuck for wedding dress were able to express easily. Hanji wedding dress has the natural texture because of natural properties of Hanji and that is echo friendly products.

Functional hanji was manufactured using the bast fiber of Broussonetia kazinoki and various inorganic compounds such as kaolin, talc, elvan, and ocher, and the physical and optical properties were investigated. The residual percentages of kaolin, talc, elvan and ocher in the functional hanji were above 50%. The density of the hanji increased with the increase of the content of inorganic compounds. The hanji manufactured using ocher showed the highest density. The breaking length and burst factor decreased with the increase of inorganic materials, indicating that physical properties of hanji were not improved by adding inorganic materials. The emission rates of far-infrared radiation increased in the hanji manufactured using inorganic materials. The higher emission rates were observed in the hanji with elvan or ocher. Addition of inorganic compounds to hanji showed the flame retardative effect. The colorfastness to light of the hanji with elvan or ocher was the degree of 4, which explained by the characteristic color of the inorganics.

Hanji is a traditional Korean handmade paper, made of bast fibers of the paper mulberry. Its fiber furnish is much more expensive than wood fiber furnish. Hanji with a low basis weight requires additional opacity and smoothness for better writing and printing. Filler such as calcium carbonate can not be used to raise the opacity of Hanji because of its low retention in low basis weight paper and the high freeness of the Hanji fiber furnish. Addition of red algae pulp, which is prepared from marine red algae to the Hanji fiber furnish negated retention problems happening in the case of mineral filler addition, and produced a substantial improvement in the opacity and smoothness of Hanji. The higher retention was due to the much larger size of the red algae fibers compared to the mineral fillers. The improvement in opacity and smoothness were also due to the shape of the red algae fibers: that red algae fibers are narrower in widths and shorter in lengths than wood fibers results in increased surface area and smoothness.

This research was performed to investigate the physical properties and color appearance of Hanji manufactured using bast fibers dyed separately by two reactive dyes with different colors. The breaking length of color Ha was above 7 km. The fastness was five grade; the use of reactive dyes made the color of the Hanji not to be faded away. The Hanji manufactured by mixing uniformly two types of bast fibers separately dyed showed the mixed color of two different colors. However, the shives showed their original colors, resulted in irregular color patterns all over the sheets. The color of color Hanji with different colors in the front and back side of sheets showed color difference between front and back side of the sheets. Accordingly, the color of the sheet has a reflection from the backside, resulted in Pink. The colors of the Hanji appeared in this study could not be found from the Hanji manufactured by traditional methods.
