D2C Growth Expands Large Molded Fiber Adoption
D2C jar brands increasingly specify molded fiber compostable inserts previously limited to small premium brands, applying cavity-engineering precision across an expanding list of mid-size regional brands as sustainability packaging commitments increasingly make documented compostability a measurable procurement attribute rather than a manageable packaging detail. This shift is creating substantial new demand beyond the category's traditional corrugated base, giving formulation-capable producers a genuine growth avenue tied to D2C adoption rather than pure corrugated-category volume growth. Producers with established brand relationships are capturing disproportionate share of this expanding demand across newly converted accounts worldwide. The paper-based bottle dividers market is a natural companion read, sized by MMA at USD 0.9 billion in 2025 with 6.3% annual growth ahead.
