각 국가 권역별 이행실험방법에 따라 지방성 및 고온가열 식품 포장재에서의 시뮬란트별 항산화제와 DEHA의 특정이행량을 비교하였다. 고온 가열용 식품 포장재의 경우 일부 두께가 두꺼운 필름, 예를 들어 PP 필름에서는 각 국가 권역별 시뮬란트 종류와 온도 조건의 차이에 따른 항산화제의 이행량의 차이가 나타났다. 미국이나 유럽연합에서 지방성 식품의 시뮬란트를 이용하여 얻어진 실험치에 $2{\sim}5$의 reduction factor가 계산되는 것을 감안한다면 아시아 조건하에서의 이행치가 유의적으로 높아지는 결과를 초래하게 된다. 아시아의 이행 실험 조건은 해당포장재의 온도 노출 조건에 따라 다양하게 설정될 필요성이 제기되었다.

국내배추의 유통 및 포장실태를 조사하고자 1999년 1월 중순부터 1999년 12월까지 생산지별로 전남. 북, 경남. 북 지역 출하실태를 산지단계, 도매 및 소매단계에서 포장실태를 조사하였다. 수박의 품위를 조사한 결과 4등급으로 거래되며 특대는 $8.91{\pm}1.06kg$으로 등급간에도 86%의 중량차이가 나타났고 당도의 경우 130%의 차이가 있었다. 유통단계별 포장실태는 산물출하가 대부분이었으며 일부에서 골판지 상자나 Wooden-Collar가 사용되고 있었다. 포장단위는 8-10kg, 한 개용 및 4개용 등이 미미하나마 포장하여 유통되고 있었다.

PET $16{\mu}m/dry$ lamination/Al-foil $7{\mu}m/dry$ lamination/CPP $80{\mu}m$의 사양으로 2개 업체에서 제조된 포장용 복합필름에서 제품 충전공정 중에서 발생한 열접착 트러블의 원인을 규명하고자 복합필름을 분리하여 각각의 두께와 재질이 제시된 사양과 일치하는지를 관능검사와 IR, DSC로 측정한 결과 1개 업체의 것이 차단층의 두께가 다르고 열접착층 필름의 재질은 비슷한 것임을 알았고, 시험기로 찾은 최적 열접착조건은 $195^{\circ}C$와 $210^{\circ}C$로 $15^{\circ}C$의 차이를 보였으며 이를 종형 4면 액체충전포장기로 직접 충전 포장하였을 때의 봉지의 열접착 강도를 비교한 결과 최적 열접착 조건 $195^{\circ}C$의 것은 평균 $4.76kg/cm^2/15mm,\;210^{\circ}C$의 것은 평균 $3.84kg/cm^2/15mm$이었다.

This study was carried out to investigate vibration shock and dropping shock of refrigerator during physical distribution. The values of vibration shock were measured to be ${\sim}3G$ for up and down direction, ${\sim}0.8G$ for right and left direction and ${\sim}0.5G$ for back and forth direction on the national road. There was no damage during transport. From the results of dropping test by KS A 1026(General Rules of Performance Testing for Packaged Freights), relative equations were gained as follow : y = 0.12x + 7.63(where y is G-factor and x is Dropping height). The maximum values of dropping shock during materials handling were measured to be 11G. This shock value was corresponding to dropping shocks of dropping height 28.3cm by KS A 1026.

In this study, the physical properties of starch adhesive by temperature in carrier and main part for the Stain-Hall method were analyzed. The temperatures of starch solutions in carrier part were inversely proportional to the viscosities. The viscosities of starch solutions were maintained similarly if 2nd temperatures were same independent on the those of the 1st temperatures in carrier part. the starch solutions showed similar viscosities in all range except the viscosity of the solutions in $30^{\circ}C\;and\;40^{\circ}C$. The viscosities of starch adhesives in main part were in proportion to those of starch solutions in carrier part. The viscosities of starch adhesives in main part were maintained similarly if 2nd temperatures in carrier part were same. The viscosities of starch adhesives in main part were low when the ultimate temperature of starch solutions in carrier part were high.

This study were conducted to reveal the awareness and competitiveness of Korean packaging industry in information technology(IT) and e-commerce. For the survey, 114 sample companies were selected representing all packaging materials, equipment and systems, institutes, consulting and trading companies. The trained interviewers spoke to the respondents who were at the position of packaging research and development and were considered knowledgeable about the level of IT in the company. The collected data were analyze in three major categories: IT fundamentals, usages, and company policy. From the results, packaging suppliers were at the very low level of IT fundamentals and uses compared to those of packaging users. The gap between packaging suppliers and users that access the Internet was seriously wide, and this trend was generally due to different size of company. Packaging suppliers were still at the basic level of information-oriented working environment.
