Freight Cost Pressure Expands Large Lightweight Adoption
Converters increasingly specify lightweight and high-performance corrugated board previously limited to small-batch premium mills, applying fiber-formulation precision across an expanding list of mid-size regional converters as freight-cost pressure increasingly makes documented strength-to-weight ratio a measurable procurement attribute rather than a manageable material detail. This shift is creating substantial new demand beyond the category's traditional single-wall base, giving formulation-capable mills a genuine growth avenue tied to freight-cost adoption rather than pure single-wall-category volume growth. Mills with established converter relationships are capturing disproportionate share of this expanding demand across newly converted accounts worldwide. The corrugated fiberboard market is a natural companion read, sized by MMA at USD 145.0 billion in 2025 with 4.6% annual growth ahead.
Market Impact: Sustains 17% of single-wall volume
