Three-layer model

PackIndex tracks three tiers of the packaging supply chain: L1 Raw Materials (pulp, polymers, metals, energy), L2 Semi-finished intermediates (board grades, films), and L3 Finished Unit Indices (CORR, FLEX, RGID, PAPR, FOAM, LABL and 20 others). Each layer feeds the next via documented supply-chain linkages.

L3 index construction

Finished unit indices are constructed from L1 and L2 input prices using a weighted bill-of-materials model, continuously calibrated by anonymised contributor Pulse signals from active packaging professionals. The model covers raw material inputs (L1), semi-finished intermediates (L2), mill energy costs, and contributor-verified pricing signals. BOM weights are reviewed quarterly.

L1 & L2 data sources

Raw material and intermediate prices are sourced from verified market data sources ingested weekly. Fibre and board prices update weekly. Polymer prices update weekly. Metal prices update daily. Energy prices update daily.

Pulse contributor system

Registered users submit directional Pulse signals — volume band, price direction vs prior quarter, lead time, supplier mood. Signals are anonymised, aggregated into a diffusion index (range -100 to +100), and used as a sentiment adjustment layer on top of the quantitative model.

Update frequency

L1 energy prices update daily. Fibre, board, and polymer prices update weekly. L3 finished unit indices are published weekly every Tuesday. Contributor pulse windows close on Tuesdays.

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. Latin American prices reflect local currency equivalents at live rates.

What indices include

Raw material commodity costs (L1), semi-finished intermediates (L2) via documented BOM weights, mill energy costs, and contributor-verified Pulse signals from packaging professionals actively trading in these markets.
