Can Molded Pulp Be pH-Neutral? Archival Safety Explained
Entity Coverage
Molded pulp can be made pH-neutral and buffered for archival use, protecting paper, photos, textiles, and artifacts from acid migration and degradation.
| Requirement | Molded pulp solution | Note |
|---|---|---|
| pH neutrality | Low-lignin buffered furnish | Prevents acid migration |
| Acid-free | Calcium-carbonate buffer | Stabilizes pH |
| Low off-gassing | Low-VOC materials | No staining |
FAQ
Q1: Is molded pulp naturally acid-free?
A: Not always. Ordinary pulp can be slightly acidic; archival molded pulp is buffered to be pH-neutral.
Q2: Will molded pulp yellow photos?
A: pH-neutral buffered molded pulp prevents acid migration, so it won't yellow stored photos or paper.
Q3: Can molded pulp protect textiles?
A: Yes. Acid-free molded pulp trays protect textiles from acid degradation over long-term storage.
