在鲜桃市场流通的保护性包装设计中，破损损失成本曲线的确定至关重要。该曲线将分布中的跌落频率数据与跌落高度的函数以及特定跌落高度的冲击造成的损坏所造成的损失的可能性相结合。对于新鲜上市的桃子，外部可见的瘀伤是造成损失的冲击损伤。在这项研究中，六个品种的桃从8 - 38厘米的高度范围内落在钢板上。目视检查其外部和内部是否有瘀伤和纤维撕裂。结果与先前研究的数据相结合，涵盖了31 - 91 cm的重叠范围。并用于计算Redhaven桃和6个品种组合的损害损失成本曲线。曲线预测了设计用于防止16 cm或更小跌落的包装的最坏情况损失在95%范围内。最坏情况损失随着包装设计范围达到46 cm而稳定下降，其中损失在10 - 20%范围内。
For the design of protective packaging for the distribution of fresh market peaches, it is important to determine the damage loss cost curve. This curve combines data on the frequency of drops in distribution as a function of drop height with the likelihood of losses occurring from damage resulting from impacts from specific drop heights. For fresh market peaches, externally visible bruises are the impact damage producing losses. In this study peaches of six cultivars were dropped onto a steel plate from heights in the range 8-38 cm. They were visually examined externally and internally for bruises and for fiber tears. Results were combined with data from a previous study covering the overlapping range of 31-91 cm. and used to calculate the damage loss cost curves for Redhaven peaches and for the composite of the six cultivars. The curves predict worst case losses in the 95% range for packages designed to protect against drops of 16 cm or less. Worst case losses decrease steadily with package designs ranging up to 46 cm where losses are in the 10-20% range.
