pH-Neutral and Archival-Safe Molded Pulp: When Packaging Must Protect Paper, Textiles and Artifacts

Ordinary paper packaging can be slightly acidic, and over years that acid migrates into paper, photos, and textiles, causing yellowing and degradation. Archival-safe molded pulp is made pH-neutral and buffered, protecting documents, garments, and artifacts over long-term storage and display.

The Scenario: Three challenges in archival packaging

Archival-safe packaging faces three challenges:

Pain Points

• Acid in ordinary pulp migrates into stored items over time, yellowing paper and degrading textiles;
• Lignin and residual chemicals can off-gas and stain photos, prints, and artifacts;
• Long-term stability demands materials that stay neutral through humidity and temperature cycles.

The Solution: Three archival molded-pulp solutions

Molded pulp offers three solutions for archival packaging:

1. pH-neutral and buffered pulp Use low-lignin, pH-neutral, calcium-carbonate-buffered furnish to keep pH stable and prevent acid migration.

2. Acid-free, low-off-gassing materials Select acid-free, low-VOC materials so photos, prints, and textiles aren't stained over time.

3. Stable storage structures Molded trays and boxes hold documents and garments flat and dust-free through long-term storage.

The Result: Preserved for decades

With these solutions, stored items stay bright and intact for decades. Molded pulp is recyclable and archival-safe, protecting heritage and premium textile brands alike.
