Poly Bag Consumption & Costing

A poly bag is a thin, flexible plastic film that protects and preserves a garment through shipping and storage, and often carries retail information too. It is a small per-unit cost, but across tens of thousands of pieces it is real money, and it is easy to miscalculate because film thickness is measured in unfamiliar units. Here is how poly bag weight, and therefore cost, is worked out.

Poly bag types

Common styles used in garment packing: heat-sealed tube, re-closeable, self-adhesive, button, zipper, flapped, gusseted, and hanger bags.
