BAG TYPES |
ORDER OF MEASUREMENTS |
|
Flat Bags |
Width X Length plus gauge |
|
Side Gusset Bags |
Width X Gusset X Lenght plus gauge |
|
Bottom Gusset Bags |
Width X Length X Gusset plus gauge |
|
|
|
|
Measuring for Flat Bag: Width x >Length
|
|
Width = Opening of bag
Length= Usable portion of bag
Gauge= Film thickness, measured in mils or microns
|
Example:
Width= 6 inches
Length = 9 inches
Gauge= .002 inches
Bag size is written as: 6” x 9” 2 mil
|
|
|
|
Measuring for Bottom Gusseted Bags: Width x Length x Gusset
|
|
Width = Across opening of the bag
Length= From opening to bottom of the bag (with gusset tucked in)
Gusset= Distance across the open face of bottom pleat
Gauge = Thickness of bag, measured in mils.
|
Example:
Width= 6 inches
Length = 9 inches
Gusset= 3 inches
Gauge = .002 inches
Bag size is written as: 6" X 9" X 3" 2mil
|
|
|
|
Measuring for Side Gusseted Bags: Width x Gusset x Length
|
|
Width = Across opening of the bag (with gusset tucked in)
Gusset = Distance across the open face of side pleat
Length = From the opening to the bottom of the bag
Gauge = Thickness of bag, measured in mils.
|
Example:
Width = 6 inches
Gusset = 3 inches
Length = 9 inches
Gauge = .002 inches
Bag size is written as: 6”x 3” x 9” 2 mil

MICRONS TO MILS FORMULA
|
|
Divide the microns by 25.4 to express micron as thickness in mils
10 microns /25.4 = .39 Mil
24 microns/25.4 = .94 Mil
|
|
|
|
MILS TO MICRONS FORMULA
|
|
Multiply the mils by 25.4 to express mils as thickness in microns
1.0 Mils = 25.4 Microns
.30 Mils x 25.4 = 7.6 Microns
.65 Mil x 25.4 = 16.5 Micron
