Poly bags
Choose bags by thickness, closure, and handling risk
The right poly bag depends on what you are packing, how sharp or heavy the item is, whether the bag needs to seal, and how much handling it will face.
Use this page to route by mil thickness, bag format, and workflow. If you are unsure, start with the thickness selector.
Choose by Mil Thickness
Higher mil bags are tougher, but they cost more and may be unnecessary for light products.
Choose by Bag Type
Different bag styles solve different handling problems across packing, fulfillment, storage, and returns.
Choose by Use Case
Poly bags are often the right choice for moisture protection, grouping, dust protection, or inner fulfillment packaging.
