Why Plastic Sleeves and Folders Can Damage Important Documents
Plastic is commonly marketed as “protective”, but when it comes to paper documents, it often does more harm than good.
The hidden issue with plastic storage
Many plastic sleeves:
- Trap humidity
- Restrict airflow
- Create static
- Leach chemicals over time
These conditions accelerate deterioration, especially in warm or humid environments.
Moisture and mould risk
Paper stored in plastic is far more vulnerable to moisture damage. Even small changes in temperature can cause condensation inside sealed sleeves.
Over time, this can lead to:
- Warping
- Sticking
- Ink transfer
- Mould growth
Chemical breakdown
Some plastics release compounds as they age. These can interact with paper and ink, causing yellowing or fading.
Better alternatives
Breathable, acid-free materials allow documents to remain stable while protecting them from handling and pressure.
Preservation is not about sealing paper away — it’s about creating the right conditions for longevity.
When protection becomes damage
The intention behind plastic storage is understandable. But true protection requires understanding how paper behaves over time.
Sometimes the most common solution is the least suitable.
