Round & Rectangular Containers

Round Container
1) To determine circumference of the bag, multiply the the diameter of the container by 3.14. Divide that total by 2 to get the flat width you need for your bag. (Add l inch for a looser fit.)
2) Add 1/2 of the diameter to the height of the container. Add 5 inches to this total for overhang. This is the total length of the bag needed.
3 )If tying bag, add 1/2 the diameter to the bag length in # 2
Rectangular Container
To determine the size of a rectangular container, do the following: (In parenthesis are a sample for a carton 14" length x 12" width x 21" depth)
1) Bag width = L + W + 2 (28 = 14 + 12 + 21)
2) Bag length = Depth + 1/2 shortest side + 5" (32 = 21 + 6 + 5)
The ideal bag is 28 x 32 x Gauge or 16 x 12 x 32 x gauge.
