Three-Layer Model
L1 Raw Materials — verified market data ingested weekly covering fibres, polymers, metals, and energy. Forms the foundation of all PackIndex values.
L2 Semi-Finished — derived from L1 using documented bill-of-materials conversion weights. Covers board grades, films, and intermediate materials.
L3 Finished Units — BOM-weighted sum of L2 inputs plus mill energy overlay, adjusted by Pulse contributor signals (±15%). Published every Tuesday.
Pulse Contributor System
Packaging professionals submit directional signals (price trend, volume, lead time, supplier mood) for any category. Signals are anonymised, aggregated into a diffusion index (−100 to +100), and applied as a sentiment overlay on L3 values. Contributors earn credits that unlock additional PackIndex features.
Geographic Coverage
All indices are published in USD with live conversion to EUR, GBP, CAD, BRL, MXN, CLP, and COP. North American polymer prices are also displayed in ¢/lb and $/short ton — standard North American trade units. Latin American prices reflect local currency equivalents at live rates.
