What a real Poly Mailer / Courier Bag supplier quote looks like
The PackIndex POLY_MAILER index tracks material cost only. A real delivered supplier quote for a poly mailer / courier bag typically runs 40–50% higher once conversion, overhead, and converter margin are added. Use POLY_MAILER as the material-cost anchor for benchmarking — not as the expected invoice price.
| Cost component | Typical contribution |
|---|---|
| Material (Poly Mailer / Courier Bag — this index) | $0.068 $/unit |
| Conversion & labour | +12–18% |
| Overhead | +8–15% |
| Converter margin | +10–18% |
| Indicative delivered quote | $0.095 – $0.102 $/unit |
The real spread varies by region, annual volume band, print/spec complexity, and freight. A quote landing more than ~50% above the POLY_MAILER index for a standard spec is worth challenging — benchmark it line-by-line with the PackIndex Quote Analyser.
