The study aimed to review linerboard compositions of corrugated fiberboard boxes for Oriental melons(Cucumis melon L. var makuwa), analyzing relationships among material compositions, price, weight of boxes, theoretical compression and bursting strength of various liner boards. 19 and 22 different liner boards were currently used for the bleached and the unbleached corrugated boards, respectively. The corrugated board containers with the bleached liners were mostly used in the market although the average price was 10 percents higher than the unbleached. The average compression strength of the bleached. We strongly recommend to redesign the boxes because the average compression and bursting strength of the current boxes were much higher than national packaging standards as much as 70 and 82, respectively.

In order to find effective linerboard compositions for the corrugated fibreboard containers for apples, we have evaluated the strength and the cost effectiveness of the various linerboards and corrugated fibreboard containers. From the results, we suggest SC240, WLK210 or SK180 for the outer liners, M180 to M250 for the mediums, and K2200 or Al80 for the inner liners, respectively. Furthermore, we recommend two cost effective types of corrugated fibreboard compositions, SC240/S120/S120/M160/A180 for the white face liners, and SK180/M180/S120/M180/A180 for the color face liners. Evidence has been presented to support the conclusion that the new high compression strength corrugated fibreboard containers have better performance in the compression and bursting strength tests, while reducing material costs by thirty four percents.

It is very important to utilize effectively fibrous waste paper in terms of cost savings, environmental effects, and governmental policies. The quality of final products and runnability of papermaking process are primarily affected by constitutions of fibrous raw materials. In specific, board grade paper depends directly on compositions of waste paper bales. At present, the raw materials of board grade paper are mainly derived from lots kinds of wastepaper. Some papermaking countries, like EU, USA and Japan have advanced classification and management systems of recycled fiber, but Korea has not yet organized systematically. In this study, evaluation of wastepaper bale compositions and their fiber properties were carried out for effective utilization of fibrous raw materials for board grade paper production. 3 kinds of wastepaper bales were classified to fibrous or non-fibrous materials. In case of fibrous materials, KOCC, kraft sack paper and white duplex board matters were main component in total weight basis, and in case of non-fibrous materials, vinyl, plastic and cloth matters were main component, in turns. 3 representative kinds of waste paper were disintegrated and classified, and then prepared to handsheet for evaluation of recycled fiber property. Consequently, fines and ash content of waste paper, isolated from KOCC and white duplex board were higher than that of kraft sack paper. pH values of all kinds of waste fibers were neutral or weak alkaline.

The purpose of this research was to complete basic study about standardization of corrugated fibreboard containers for apples. Various corrugated fibreboard containers are studied and the results are shown below. 1. WLK, SK, and KA are usually used for outer liner boards, S and $K_2$ are for medium or inner liner boards. 2. According to the study, about twenty different liner compositions are currently used for apple packaging. However, for the containers with white liner board, the liner composition is WLK210/M200/S120/$M200/K_{2}200$, for the containers with colored liner board, SK180/M200/S120/$M200/K_{2}200$ are mostly used. 3. Sixteen percents of cost saving are expected when subsitute white outer liner boards by those of colored.
