Spy apples in separate plastic storage units were in excellent condition after 
6 to 7 months. Care was necessary not to perforate the film walls by rough 
handling. Rodents were another possible source of leaks. 
Chace, Dewey, and Pflug (5) enclosed 2,460 bushels of McIntosh apples in 
a tent made of 8-mil vinyl film within a regular storage room. Details of this 
technique are in the section on Controlled-Atmosphere Storage. 
Johansson (35) found that a l-mil polyethylene enclosure over approxi- | 
mately 250 boxes stored at 40° F, served as a satisfactory controlled-atmosphere | 
chamber for Cox's Orange and Ingrid Marie apples. Leblond (38) reported that 
ethylcellulose was a good film for plastic gas storages at a relatively high 
temperature of 54°, He described the requirements of films for fruit storage 
as permeable enough to water vapor, very permeable to volatile organic materials) 
and not very permeable to oxygen and carbon dioxide.
