개발된 항균 포장 원지를 이용하여 포장 봉지(packaging bag)와 골판지 포장 상자(corrugated box)를 제작하였고, 여기에 과채류를 포장하였을 때 일반 포장 봉지나 골판지 상자에서 포장된 과채류 보다 변패 미생물의 발생이나 생체중 감소가 상당히 줄어들었다. 이는 BAAG에 의해 과채류의 변패에 관여하는 미생물의 생육을 차단하였고, 제올라이트에 의해 과채류의 조직을 빠르게 연화시키는 기체들인 에틸렌가스, 이산화탄소 및 산소가 제거되었으며, AKD에 의해 과채류가 보유한 수분 손실을 최소한으로 일어나게 하였기 때문이다. 결론적으로 BAAG, 제올라이트, 그리고 AKD로 처리된 포장 원지를 이용하여 제작한 포장대(packaging bag)과 골판지 포장 상자는 저장 과채류의 선도를 유지하는 데 탁월한 효과를 발휘하였고, 기능성 첨가제의 처리로 인한 제조 원가의 상승은 폐기 과채류의 양이 감소하면서 상쇄시킬 수 있었다. 따라서 일반 골판지 상자에 저장된 과채류보다는 기능성 골판지 상자에 저장하는 방법이 보다 경제적인 저장 방법이 될 수 있음을 확인하였다.

This paper provides an overview of kimchi packaging technology, focusing on packaging materials, package design, and active/intelligent packaging technology for kimchi. From a packaging-material standpoint, although various materials have been used to ensure customer satisfaction and convenience, plastic is the most widely used material, in the form of bags, trays, pouches, and rigid containers. Additionally, recent efforts in the kimchi packaging industry have allowed companies to differentiate their products by using different packaging materials and technologies, while simultaneously improving product safety and quality. On the other hand, the biggest problem in kimchi packaging is excess $CO_2$ production, leading to package expansion and leakage. To alleviate this problem, the use of $CO_2$ absorbers, high $CO_2$-permeable films, and degassing valves, in addition to the use of different packaging systems, has been investigated. Active and/or intelligent packaging systems have been developed, to include active functions beyond simply inert, passive containment and protection of the kimchi product. However, most such approaches are not yet adequately effective to be useful on a commercial scale. Therefore, further studies are needed to resolve the limitations of each technology.

In order to reduce packaging and logistics costs for any business, it is important to identify opportunities for improvement throughout an entire logistics system including measurement of the performance and cost of packaging. Although the importance of packaging in a supply chain has been recognized by many scholars and experts, the total cost and value of packaging have not been successfully estimated. This paper reviews the recent researches and articles that tried to quantify the value of packaging focusing on the business decision between reusable and expendable shipping container systems. Three key factors such as cost, ownership, and standardization are identified and discussed in terms of impact on supply chain costs and performances. It is important to understand that the decision of a package system can change a logistics activities and even entire logistical system. Hence, the total cost and value of transport packaging should be calculated with understanding of interactions with logistical activities throughout supply chain. Identifying the opportunities and constraints of packaging changes on total logistics cost and activities must be carefully examined before implementation of a packaging system.

As the demands of environment protection increases, the pulp mold container is developed to substitute for EPS (expanded polystyrene) as a shock absorbing packaging material. The water-absorbing ratio and mechanical properties such as tensile strength and compressive strength of pulp mold are important factors to evaluate its shock absorbing characteristics. Influences of mixing ratios of ONP (old newspaper) and OCC (old corrugated container) on physical properties of pulp mold were investigated at various conditions of temperature and relative humidity. The optimum mixing ratio of ONP and OCC was also searched based on physical properties. The results showed that when relative humidity was increased from 60% to 90%, the water absorption ratio of pulp mold increased significantly, tensile strength decreased 20$\sim$30%, and compressive strength decreased 10$\sim$20%. In addition, the optimum mixing ratio of ONP and OCC was found to be 50%:50%.

Paper angle, environment friendly packaging material, has been mainly used as an edge protector. But, we have perceived its application to package design of heavy product such as strength reinforcement or unit load system (ULS) in the future. Above all, understanding of buckling behavior for angle itself and compression strength and quality standard have to be accomplished for the paper angle to be used for this purpose. The purpose of this study was to elucidate the buckling behavior through theoretical and finite element analysis, and to develop compression strength model by compression test for symetric and asymetric paper angle. Based on the result of theoretical and finite element analysis, increasing rate of buckling of asymmetric paper angle was higher as applied load level was bigger and/or the length of angle was longer than that of symmetric paper angle. Decreasing rate of minimum principal moment of inertia was remarkably increased as the extent of asymmetric angle is bigger, and buckling orientation of angle was open direction near the small web. Increasing rate of maximum compression strength (MCS) for thickness of angle was smaller as the web size was bigger in symmetric angle. MCS of asymmetric angle of $43{\times}57$ and $33{\times}67$ was decreased $15{\sim}18%$ and $65{\sim}78%$, and change of buckling was increased $12{\sim}13%$ and $62{\sim}66%$, respectively.

It is very difficult to export the fresh agricultural products to long distant countries such as America and EU without any damage. Fresh exporting products would be met very hazardous environments such as hot and cold weather, heavy trembles with rolling and pitching. Therefore, care should be taken on tight fastening the products inside the container and keeping the designated temperature and relative humidity. The physical strength of outer box should be applied differently because each agricultural product has its own character for packaging. There have been many agricultural products researches for export packaging to the U.S.A. so far. However they have never got desirable results which enough to apply it in real. The main purpose of this research is to develop optimum compressive strength of corrugated fiber board box which would be used to American export packaging of fresh agricultural products such as perilla leaves, green red pepper and spinach.
