Often, we are asked what thickness plastic zip Locking bags we need for different applications. We are happy to help guide you on what to use and provide samples to compare. Use this guide as a starting point for the various thickness offered in our stock ClearZip® zipper locking bags. Gauge or Thickness is expressed in mils, 1000th of an inch. One mil equals .001”. A standard consumer-brand Ziploc sandwich bag is about 1.4 mil thick. And most consumer-brand freezer bags are 2.4 mil thick. Please Note: Industry standard tolerance for thickness is +/- 10%.

ClearZip Locking Bag Sizes: How To Measure Bags Dimensions

How do you measure a zip-locking bag for your application?

Bags are measured and communicated in inches as width first, then by length. The Width is measured side to side when the bag is orientated with the opening at the top; the length is measured from the zipper track to the bottom. Please note that the Lip (area above the zipper) is NOT included in the length dimension. For bottom gusset bags, measure the open gusset across and communicate it as W x L +B.G: ie, 6” x 8”+4”. Please Note: Industry standard tolerance for size variances is +/- 1/8 inch to both dimensions.

Ours are usually thicker and very dependable because of their secure locking top, which provides an excellent way to keep out foreign substances that can compromise your products. Most of our zip bags are made of Low-Density Polyethylene or LDPE plastic film but can also be custom-made to your specifications.


Every business imaginable uses Zip Locking bags in one way or another. Whether industrial, commercial, or residential, you can be assured that a Zipper lock bag is being used.

The side of the bag that opens is always in the width dimension. All ClearZip® lock-Top bags are measured by the usable inside dimensions (without the zipper or lip included in the overall measurements). No matter what resealable poly bag or open-end poly bag you choose from us, they all meet FDA and USDA specifications for food. Your packaged contents are on display, visible through the clear LDPE. The zip-top seal allows them to be closed, opened, and resealed repeatedly. This makes these bags perfect for items that must be kept fresh or repackaged.


It would be difficult to find another product that is more widely used, no matter by what name you call it. When there are items needing protection, and organization, coupled with the need to be repackaged, there is no better solution than International Plastic's ClearZip® Zip Locking Bags.


We are the leading online wholesale supplier of ClearZip® industrial zipper-lock bags. Our ClearZip® Zip Locking bags are not the same as consumer sandwich, storage, and freezer brands marketed to home consumers. Our bags are thicker and much cheaper than consumer-branded bags.
