What are Poly Bags?

Poly Bags are small bags made from FDA and USDA-approved plastic material, such as polyethylene (PE) or polypropylene (PP). Perfect for storing and organizing small items, these bags come in different sizes, shapes, and thicknesses to suit different purposes. Many poly bags come with reclosable openings, allowing for multiple uses and minimal waste.

What is Mil Thickness?

Mil is the standard unit of measurement for poly/plastic bags. Also known as a thou or a point, a mil is one-thousandth of an inch. For reference, human hair is roughly 4 mil thick.

Most poly bags will be available in the 2-3 mil range, with some specialty bags coming in at 1.5 and 4 mil.
