Packaging Cost Benchmark Q1 2026: What Every Procurement Team Needs to Know

Q1 2026 PackIndex Snapshot

The first quarter of 2026 has delivered the starkest divergence between corrugated and flexible packaging costs since 2022. The PackIndex CORR corrugated RSC index stands at $0.486/unit — up 14% year-on-year — while FLEX flexible pouch has eased to $0.370/unit, down 1.4% over the same period.

The Corrugated Story

OCC (Old Corrugated Containers) is the primary driver at $188/t — an 18% YoY increase. Mill restocking across Central Europe, combined with below-average recovery fibre collection volumes in Germany and the Benelux, has kept the market tight through Q1.

The Flexible Opportunity

Polypropylene resin (PP) has softened as Asian capacity additions weigh on European import prices. The PackIndex PP L1 index is at $1,149/t — down from a Q3 2025 peak of $1,312/t. BOPP film, which tracks PP with a 4-6 week lag, has followed.

For buyers with mixed corrugated and flexible specifications, this is the widest relative value gap in four years. A corrugated-to-flexible conversion study is worth commissioning now.

What to Do This Week

1. Run the Quote Checker on any corrugated renewal quotes — expect 8-14% above the $0.486 benchmark to be flagged as HIGH or OVERPRICED.
2. Review flexible specs — if a corrugated shipper can be substituted with a flexible pouch at equivalent protection, the $0.116/unit spread is worth modelling.
3. Check OCC index clause — does your converter contract have one? If not, the next renewal conversation will be one-sided.
