About the Kraft Paper Bag Index
PackIndex PAPR tracks the material cost of a kraft paper bag/sack — the reference format for paper-based flexible packaging in food service, retail, and industrial markets. The 5kg SOS (Self-Opening Square) sack is the reference spec. Primary driver is sack kraft paper (KRAFT), which tracks NBSK pulp.

What a real Kraft Paper Bag supplier quote looks like
The PackIndex PAPR index tracks material cost only. A real delivered supplier quote for a kraft paper bag typically runs 40–50% higher once conversion, overhead, and converter margin are added. Use PAPR as the material-cost anchor for benchmarking — not as the expected invoice price.
| Cost component | Typical contribution |
|---|---|
| Material (Kraft Paper Bag — this index) | $0.666 $/unit |
| Conversion & labour | +12–18% |
| Overhead | +8–15% |
| Converter margin | +10–18% |
| Indicative delivered quote | $0.933 – $0.999 $/unit |
The real spread varies by region, annual volume band, print/spec complexity, and freight. A quote landing more than ~50% above the PAPR index for a standard spec is worth challenging — benchmark it line-by-line with the PackIndex Quote Analyser.
