Basics of Poly Bag Measurement

When looking at poly bag sizes, it’s good to know how to read a manufacturer’s bag dimensions. Know that with any size or shape of poly bag, the bag’s width is always the first measurement. Take a look at the chart below for a quick guide showing you how to measure poly bags depending on their style.

A Few Considerations To Make When Measuring Poly Bags
  • Measure your product first. Before you consider what size poly bags you’ll need, it’s important to have a complete measurement of your product. This will help you choose the appropriate size poly bag for your order.
  • Consider the poly bag’s opening size. Always be sure to check that the poly bag’s opening size will be wide enough to accommodate your product’s unique dimensions.
  • Not sure where to start? Ask the experts! If you’re new to measuring poly bags, please know that these instructions are just a starting point. The team at A-Pac Manufacturing is always happy to talk to you directly to help you find the best poly bag size for your exact needs.

How to Measure Poly Bags

Flat Poly Bags

Example:
W = 8″ & L = 18″
Dimensions = 8″ x 18″

Gusseted Poly Bags

Example:
W = 8″, G = 4″, & L = 18″
Dimensions = 8″ x 4″ x 18″

Wicketed Poly Bags

Example:
W = 10″, L = 12″, & Lip = 1.5″
Dimensions = 10″ x 12″ x 1.5″

Barrel Liners

For bag width:  D x 1.57 + 2″
Example:  D = 23″
23″ x 1.57 + 2″ = 38″

For bag length:  D + H + 6″ tie off
Example:  D = 23″ & H = 36″
23″ + 36″ + 6″ = 65″

Bag Dimensions = 38″ x 65″

Box Liners

Length & Width:  L + 2 x W + 2
Example:  L = 50″ & W = 42″
50″ + 2 x 42″ + 2″ = 52″ x 44″

Height:  H + W + 6″ tie off
Example:  H = 40″ & W = 42″
40″ + 42″ + 6″ = 88″

Dimensions = 52″ x 44″ x 88″

Palette Covers

Length & Width:  L + 2 x W + 2
Example:  L = 50″ & W = 42″
50″ + 2″ x 42″ + 2″ = 52″ x 44″

Height:  H + (W x 0.5)
Example:  H = 40″ & W = 42″
40″ + (42″ x 0.5) = 61″

Dimensions = 52″ x 44″ x 61″

Bags on a Roll

Example:
W = 22″ & L = 18″
Dimensions = 22″ x 18″

Plastic Tubing

Example:
W = 14″
Dimension = 14″
