In optimum design of packaging container for bulk materials, minimum board area, compression performance and distribution efficiency must be considered. In this study, mathematical models for minimum board area (RMA), compression strength (CS) and maximum compression strength per unit board area (MCSA) of container as algorithm for optimum design of packaging conatiner for bulk materials were developed as follows : RMA=f(V,D), ${\alpha}_{RMA}=f(V,D)$, MCSA=f(V,D), and ${\alpha}_{MCSA}=f(V,D)$. In order to develop these models, compression test according to various dimensions of container and response surface analysis for minimum board area, compression strength, and maximum compression strength per unit board area of container were carried out. In developed models, volume and depth of container were principal independent variables. Through the verified results for these models, optimum design of packaging container on the design conditions and limit conditions was possible. These models might be used in developing optimum design software of packaging container for bulk materials.

Due to the rapid increase in cyber shopping mall of agricultural products, the parcel delivery service industry also increased, making it necessary to design an optimum packaging for agricultural products. And Due to the recent increase in strawberry consumption, there is also a need for a packaging system for parcel delivery service. In order to establish the criteria for optimum cushioning packaging design of strawberries, the bioyield strength of strawberries by storage time was measured through the ASABE test standards, and the peak acceleration in the resonance frequency and resonance frequency bands of strawberries was measured through the vibration test regulated in the ASTM test specifications. Tray cup pad and corrugated fiberboard box of delivery strawberries were designed using FEM theoretical analysis of contact stress and resonant frequency. In addition, an optimum packaging system was developed with a cushioning and vibration design considering the impact characteristics when distributing agricultural products. Through the performance evaluation and on-site evaluation of the optimum packaging system of strawberries for parcel delivery service, the random PSD test results of the delivery showed a 74% reduction in the acceleration level, and the actual distribution test of the delivery showed that the damage rate of strawberries was not more than 6.7%, indicating that it was possible to use the optimum packaging of strawberries for delivery.

If an optimum design technique is applied in the design of packaging container for bulk-type products, merits on the side of not only economic and compression performance but distribution efficiency are expected. Accordingly, minimum board area (mRBA), compression strength (CS) and compression strength per unit area (mCSPA) are important design parameters in optimum design of packaging container for bulk-type products. In this study, mathematical models for mRBA, CS and mCSPA of container as algorithm for optimum design program were developed. In order to develop these models, compression test by various dimensions of container and response surface analysis for mRBA, CS, and mCSPA of container were carried out. In the developed models, volume, W/L ratio and depth of container were principal independent variables. On the found of these models, optimum design program having faculties of outward and inward optimum design and information design was developed. Though the packaging specifications are same, required board area, board combination and cost of the corrugated board required container manufacture were greatly different by boundary conditions in outward design. Moreover, about 6.3∼10.1% in weight of container was lighter, and about 13.2∼25.6% in cost of container was reduced when the program was applied for 2 kinds of bulk-type products.

Software summarized packaging technology related is needed for low cost and high efficiency in production and packaging design of corrugated board, and in development of these softwares, distribution and packaging environment of one's country must be reflected, well. In domestic occasion, software related to corrugated board packaging dont's exist nearly, and in many industrial fields, the more higher role and importance of packaging in various industrial field is, the more higher necessity of that is. In this study, on the base of preceeding studies (Park, 2001; 2003; 2003), software to optimize board combination that is most importance and sensitivity in composition of cost elements in production and packaging design of corrugated board was developed. This software was composed of input module, output module, database and management module, and calculation module, and efficiency of this software was analyzed on the both sides of sensitivity in design result and effectiveness in a case analyse. In the inward design results having same strength, board combination balance, bursting strength, box weight, and cost were greatly different. Therefore, optimum inward design according to user's design specifications is possible, and in a case analysis for actual products, obtained the more profitable results than before design.

일부 화장품용기의 크기가 내용물에 비해 지나치게 크다는 언론 보도가 잇따르고 있는 시점에서 내용량 부피 대비 포장외용적의 비율을 이용한 부피 지수를 산출하는 연구를 진행하였다. 시중에서 유통되는 기초화장품 중 국내외 화장품 200개 이상을 분석하여 화장품 용기 부피지수(Lcos) 및 지수를 이용한 최적 기준, 권고기준 및 상한기준의 설계 기준을 도출하였다. 분석결과 수거된 국내외 화장품의 약 37%는 권고 기준 혹은 최적 기준을 충족시켰으며 약 15%는 상한기준을 넘어 과대한 부피를 가지는 것으로 나타났다. 또한 부피지수가 1.0에서 1.2 사이에 약 31%의 화장품이 분포되어 있으며 이러한 제품들은 향후 개발 과정에서 약간의 용기 부피 감량화 노력에 의해 권고기준 내로 디자인 변경이 용이한 그룹에 속한다고 볼 수 있었다. 본 연구의 결과물인 화장품용기 부피지수의 이용은 화장품이 과대포장 되어 있다는 부정적인 이미지를 탈피하고 제품용량 대비 적절한 외용적 및 재질 사용량에 대한 기준점을 제시하는 수단이 될 수 있을 것이다. 또한 향후 업계에서 자율적으로 연구된 지수를 반영하여 화장품 용기의 설계 및 생산 시 기준점을 잡을 수 있는 가이드라인의 역할을 할 수 있기를 바란다.

Among the many packaging materials used in cushion packaging, there is a lack of optimum design for packaging trays and cushion pads used in pear packaging for export and domestic distribution. It causes over-packaging due to excessive material input, and can be solved by applying various parameters needed to optimize the design of the packaging tray and cushion pad considering the packaging material and the number of pears in the box. In the case of a cushion pad for pears, the economic efficiency of material and thickness should be considered. Therefore, it is possible to design a packaging tray and cushion pad depending on eco-friendly packaging materials (PLA, PET) used by applying appropriate design parameters. The static characteristics of the materials used for the packaging of pears were analyzed using FEA (finite element analysis) simulation technique to derive the optimal design parameters. In this study, we analyzed the contact stress and deformation of PET, PLA tray (0.1, 0.5 1.0, 1.5 and 2 mm) and PET foam (2.0, 3 .0 and 4.0 mm) with pears to derive appropriate cushion packaging design factors. The contact stress between the pear and PET foam pad placed on PLA, PET trays were simulated by FEA considering the bioyield strength (192.54±28 kPa) of the pears and safety factor (5) of packaging design, which is the criterion of damage to the pears. For the combination of PET tray and PET foam buffer pad, the thickness of the PET foam is at least 3 mm, the thickness of the PET foam is at least 1.0 mm, the thickness of the foam is at least 2 mm, and if the thickness of the PET tray is at least 1.5 mm, the thickness of the foam is at least 1 mm, suitable for the packaging design. In addition, for the combination of PLA tray and PET foam pad, the thickness of the PET foam was not less than 2 mm if the thickness of the PLA tray was 0.5 mm, and 1 mm or more if the thickness of the PLA tray was not less than 1.0 mm, the thickness of the PET foam was suitable for the packaging design.

Physical damage to fruits and vegetables caused by shock degrades the value of product in the fresh market. In order to design a product/packaging system to protect the product, the G-factor to the product that causes shock damage needs to be determined. The shock fragility of organisms such as fruits with a concept correspondent to the G-factor of industrial products was calculated and we defined the allowable bio-shock fragility index as the value divided peak acceleration that was generated in safe drop height by standard acceleration of gravity. We did modeling for safe drop hight that would prevent fruits from damage by drop tests and tried to estimate the allowable bio-shock fragility index of pears and apples for optimum packaging design. The bio-shock fragility index of pears was in the range of $0.74{\sim}2.29\;G$, while apples had a slightly higher value than that of pears, of $0.51{\sim}2.98\;G$. This result shows accordance with the general fact that apples have a firmer structure and get less damage from the same impact. Based on this result, it is possible to create an optimum packaging design by providing a damage standard by impact.
