A mil is the industry-wide measurement unit for plastic bag thickness.
1 mil is equal to a thousandth of an inch (1000 mil = 1 inch). Most plastic bags are 6 mils or less, with the average poly bag breadth around 2 mils. This may seem like a small range, but for poly bags, there’s a big difference between 0.5 or 1 mil poly bag and a 5 mil poly bag.
Poly bags are an incredibly versatile packaging material that can be developed into varying strengths to serve any application.
