콜드체인용 골판지 상자의 냉기공과 상자의 압축강도와의 관계를 알아보고자, 골판지 상자에 각각 냉기공을 2 또는 3개를 뚫고, 냉기공의 크기와 면적을 달리하여 상온(RH 705 %)에서 4주간 저장하면서 골판지 상자의 압축강도를 측정하였다. 냉기공 면적이 4, 7, 10 %모두에서 냉기공의 크기가 폭은 좁고 길이가 긴 것이 압축강도가 높게 나타났다. 또한 냉기공 면적에 따른 압축강도를 살펴보면 냉기공 면적이 4 %인 상자가 다른 상자들에 비해 압축
To develope corrugated paperboard box for cold chain system, it was investigated to compression strength and size of air hole. The size of air holes of the side tested box were designed as six groups, 4, 7, 10% and two kind of air hole, 2, 3 hole per the side. Compression strength of box(440330170 mm(lengthwidthheight))was tested by compression tester UM-20Y, DaeSin Co., Korea, speed is 12.5 mm/min), it was stored 4 week at room temperature, RH 705%. Compression strength was high the mort narrow, the longer of air hole. Compression strength of box of the side, 4% was 10% higher among 4, 7, 10%, but differentiate of compression strength owing to the number of air hole was below 10%. for improving the compression strength of box, paper board box for cold chain system was made of the narrow of width and of the long length of air hole.
