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.

Layflat Dimensions
For each layflat bag there are three dimensions. The first measurement is the width across the opening of the bag. The length runs from the bag opening to the bottom of the bag. Gauge, the third figure in a bag's dimensions, is a measure of its thickness expressed in mils.

Gusseted Dimensions
A gusseted bag allows for your product to sit on a shelf. It is also perfect for a box liner -- it will square out in a box. The width measures across the opening of the bag when laid flat. The depth is the fully extended gusset. The length runs from the opening to the seal, and the final dimension is the Gauge, a measure of its thickness expressed in mils.
