Can bubble wrap cause damage to a painting? When it comes to storing or transporting paintings, ensuring proper protection is crucial. Many people rely on bubble wrap, a widely used packaging material, to safeguard their artwork.
But is bubble wrap actually safe for paintings? While it seems like a soft, cushioning option, using it improperly can lead to significant damage. Let’s explore whether bubble wrap is a friend or foe when it comes to preserving paintings.
Understanding Bubble Wrap
What is Bubble Wrap Made Of?
Bubble wrap is a flexible plastic material featuring air-filled bubbles that provide cushioning. It’s primarily made from polyethylene, a type of plastic known for its lightweight and shock-absorbing properties.
Why is Bubble Wrap Commonly Used for Packaging?
- Protects against physical impact and vibrations
- Provides insulation against temperature changes
- Lightweight and cost-effective
Pros and Cons of Bubble Wrap for Artwork Protection
✅ Pros:
- Protects against minor shocks and impact
- Helps in reducing direct pressure on fragile surfaces
- Available in different sizes and thicknesses
❌ Cons:
- Can trap moisture, leading to mold or paint damage
- Bubbles can leave impressions on the surface of paintings
- Plastic may cause chemical reactions with certain paint types
Potential Risks of Bubble Wrap on Paintings
1. Trapped Moisture Issues
Bubble wrap is not breathable, meaning it can trap humidity inside, which may lead to mold growth or paint softening, especially for oil or acrylic paintings.
2. Imprint Damage from Bubbles
If the bubbles directly touch the painting’s surface, they can leave permanent indentations, particularly on varnished or soft paint layers.
3. Chemical Reactions with Paint or Varnish
Some plastics release chemicals over time that can react with paint or varnish, causing discoloration or surface deterioration.
4. Static Electricity Concerns for Certain Mediums
For artworks created with pastels or charcoal, bubble wrap can generate static electricity, which may lift or smudge pigment.
Best Practices for Using Bubble Wrap on Paintings
If you must use bubble wrap, follow these guidelines to minimize risks:
- Never let bubble wrap touch the painting surface directly.
- Wrap the painting in a protective layer first, such as acid-free tissue paper or glassine paper.
- Use the bubble side facing outward to prevent indentations.
- Avoid sealing the wrap too tightly, allowing some airflow.
Alternative Materials for Wrapping Paintings
For better protection, consider these safer alternatives:
- Glassine Paper – A smooth, non-stick material that prevents moisture and dust damage.
- Acid-Free Tissue Paper – Helps protect delicate surfaces without chemical interference.
- Foam Board and Custom Crates – Ideal for high-value artwork that needs long-term storage or shipping.
How to Store and Transport Paintings Safely
Ideal Storage Conditions
- Keep paintings in a cool, dry environment with stable humidity levels.
- Store them vertically to prevent pressure damage.
Handling Tips for Delicate Artwork
- Wear gloves to prevent oils from hands transferring to the surface.
- Avoid stacking paintings without proper padding in between.
Preventing Accidental Pressure Damage
- Use corner protectors and a rigid backing board.
- Secure artwork in a custom-built wooden crate for long-distance transport.
Conclusion
While bubble wrap offers some level of protection, it is not the best choice for directly wrapping paintings. The risks of moisture trapping, surface damage, and chemical reactions make it a poor long-term solution. Instead, opt for acid-free materials like glassine paper or foam boards for better preservation. If you do use bubble wrap, always ensure there is a protective barrier between it and the artwork.
FAQs
1. Can bubble wrap ruin an oil painting?
Yes, if applied directly, bubble wrap can leave imprints, trap moisture, or cause chemical reactions with oil paint.
2. Is there a safe way to use bubble wrap on artwork?
Only if you first wrap the painting in glassine or acid-free tissue paper and keep the bubble side facing outward.
3. What should I use instead of bubble wrap?
Glassine paper, foam boards, and custom crates are better alternatives for storing and transporting paintings safely.
4. How long can a painting stay wrapped in bubble wrap?
Not for long. Extended wrapping in bubble wrap can lead to trapped humidity, which may cause mold or surface damage.
5. Does humidity affect paintings wrapped in plastic?
Yes! Humidity can get trapped inside plastic wrap, leading to mold growth or paint deterioration over time.
