Abstract:
The effect of packaging on the buffering capacities of hami melon during dropping process was evaluated. The hami melon was packaged by the 3, 5, and 7-layer corrugated carton, or filled by 5 different fillers. And the gravity acceleration of the packaged melon was measured during the dropping process. The 7-layer corrugated carton presented the lowest acceleration, 3.6% and 2.1% lower than the 3-layer and 5-layer corrugated carton, respectively. The acceleration presented the negative correlation with its thickness and edgewise compressive strength with the correlation of -0.987 and -0.994, respectively. The bulk pearl cotton presented the lowest acceleration, being of 27.1%, 23.2%, 11.5% and 3.9% lower than the EPE pearl cotton, bubble column, corrugated paper and bubble film, respectively. The strongest buffering capacity of the bulk EPE pearl cotton was caused by the porous structure. Moreover, the porous structure facilitated the air circulation of the Hami melon. Hence, the bulk EPE pearl cotton is a potential package for the Hami melon.
