Of course, 150 cartons a day is the best cost savings scenario
It is based on the following assumptions :
Average carton dimension : 12x12x16 in
Average void to fill : ¼ to 1/3 cu. ft.
On a yearly basis : 9,500 to 12,000 cu. ft.
Equates to 4 to 6 rolls per month
Below this threshold: scenario: MINI PAK'R is the best machine
