골판지상자에 기능성 필름을 첨합한 포장상자(FC)의 배 저장 중 품질유지 상태를 조사하고자 대조구로 기존에 유통중인 골판지 상자와 0.02, 0.04mm의 LDPE필름과, 0.02와 0.04mm의 기능성MA필름(CE)에 배를 포장하여 5 C에 60일간 저장하면서 신선도 변화를 비교 고찰하였다. 중량변화는 대조구는 2.9% 감소했으며, FC, LDPE와 CE 포장구들은 1.0-0.5% 감소했다. 경도는 각 포장방법간에 차이가 없었으며 비타민C 함량

Weight loss of fear packed with corrugated paperboard box(FC) laminated with functional MA film after 60 days storage at 5 was 1.0%, and that of LDPE, CE film was 0.6-0.7%, while that of control(Corrugated Paperboard box) was 2.8%. Total ascorbic acid content of pear ill MA films and FC package was higher than that of control. Titratable acid of control changed 37%, but that of the others packages changed below 27%. Soluble solid content of control changed 27%, while the others changed below 2%. Reference in overall appearence of pear were not found among packaging methods. Corrugated paperboard box(FC) laminated with Functional MA film can be used as packaging material for pear packaging.
