Understanding Poly Bag Mil Sizes

Understanding poly bag Mil sizes or thicknesses will help you select the right option for your products. Choosing the right poly bag Mil is crucial for the success of your packaging strategy. Mils that are too small might end up tearing during transit, which can cause product damage. Mils that are too large on the other hand provide plenty of protection, but they can be costly compared to the Mil you actually need to get the job done. Let's look at the different poly bag Mil sizes available.
