A Study on the Quality of Liner Board Used Corrugated Fiberboard Container of Apples

사과포장용 골판지 라이너원지의 품질에 관한 연구

As strait As a result of the quality research of liner boards used for the national-made corrugated boxes for apples, basis weight of each sample passed its tolerance within 4%. We found that KA, WLK, and SC liner boards showed better in relative bursting strength. SC, WLK, KA, and SK performed better in relative compression strength. WLK201 and KA210 were good for the outside liner, and K2200 was adequate for medium and inside liner. we classified WLK and KA liner boards as A grade and others as C grade.
