Example:

                         A. Length =50"

                               B. Width =44"

                               C. Depth =48"

                                                        Rectangular Containers

1. For a plastic bag acting as a cover, add approximately 4" to either "A" or "B" for a loose fit.  For the height, add half of "B" to the actual height of the box.

A: 50" + 4" = 54"
B:               =44"                 Size to order: 54"x44"x70"
C:  48" + 22" = 70"

2. For a box, tub or hopper liner, use the same procedure as above for width and lenth.  For height, add all of dimension "B" to the actual height plus a few inches for overlapping the ends of the liner.

A: 50" + 4"= 54"
B:             = 44"                  Size to order: 54"x44"x96"
C: 48" + 44" + 4" =96"

                                                                    

                           Round Containers

                  1. Circumference = Diameter X 3.33*
                  2. Lay flat width of bag = 1/2 circumference
                  3. Length= L + D + 4"   (4" is overhang for tying)

 Example:

L = 31"                               Width = 1/2 (D x 3.33) = 1/2(24" x 3.33) = 40"
D = 24"                               Length =L + D + 4" = 31" + 24" + 4" = 59"
                                          Bag Size = 40"x59"

* Pi=3.14 but 3.33 allows extra girth for ease of filling the bag.
