Having the right thickness for your poly bags is very important. If you choose a gauge that is too small, you run the risk of having the poly bag puncture or break. Or you might end up spending more than necessary for a thick gauge that is not needed for your application. In order to choose the right gauge, take into consideration what is most suitable to your product's proper display and support.
