Results are shown in Table 2. These tests shcv/ed that (1) 

 more injury occurred in dry fiber trays than in moist fiber trays; 

 (2) more injury occurred in shallow fiber trays than in deep-cell 

 fiber trays; (3) damage to fruit packed in fiber trays can be 

 reduced by individually wrapping apples in paper, padding the 

 bottom of the carton, and especially by putting pads between layers; 

 and (4) cold apples are more subject to bruising than are warm 

 apples . 



Clearly, the way apples are packed influences the amount of 

 damage inflicted by impact upon the carton. However, the clearest 

 m.essage from these studies is: Don't drop cartons of apples!
