‘arton. It is suggested that sealed film liners should be used only 
for that portion of the tonnage destined for late storage (after Janu- 
ary), as visible shrivel rarely develops before that time in Golden 
Delicious apples packed in the standard wooden apple box. 
Linuted commercial use of Pliofilm 80 FM1 and polyethylene 150 
as sealed liners for packaging Golden Delicious apples in cell cartons 
was made during the season of 1952. About 4,000 cell cartons were 
packed and stored until April and May before shipment. Trade ac- 
ceptance was excellent; the fruit sold for premium prices as high as 
$11.72 per carton for one of the last carlot shipments. ‘There were 
approximately 67,600 boxes (loose and packed) of Golden Delicious 
apples held in sealed polyethylene liners during the season of 1953. 
The results obtained in this study show that it is possible to improve 
the appearance and prolong the storage life of pears and Golden 
Delicious apples by packaging them in certain sealed film box liners 
at harvest. Hazards due to improper handling and to fruit decay 
must be recognized. With intelligent use of these films, however, the 
marketing season of Bartlett, Bosc, Comice, and Anjou pears, and 
Golden Delicious apples can be significantly extended.
