Protecting the delicate surface of oil paintings during transport and storage is crucial to preserving their aesthetic and financial value. This comprehensive guide explores the most effective wrapping materials—including acid‑free glassine, acid‑free tissue, closed‑cell foam, bubble wrap, Tyvek, and Mylar—to prevent scuffs and abrasion. We also discuss best practices for layering these materials, additional protective components like corner guards and rigid boards, and fundamental crate design considerations to safeguard oil paintings from shocks, humidity changes, and pests. Finally, learn how Union Fine Art Services provides bespoke art packaging and crating solutions backed by decades of experience, ensuring your artwork arrives in pristine condition.
Why Proper Wrapping Matters for Oil Paintings
Oil paint surfaces can be deceptively soft even after drying, making them susceptible to scuffs, abrasions, and sticking to adjacent wrapping materials during shipment. Regular paper or plastic in direct contact can adhere to or chemically interact with the paint layer, causing irreversible damage. Proper wrapping materials act as an inert, non‑abrasive barrier between the paint surface and outer packaging layers, preserving not only the visual integrity but also preventing issues like paint flaking, cracking, and off‑gassing over time.
Acid‑Free Glassine Paper
Overview
Glassine is a smooth, glossy, semi‑transparent paper that resists moisture and grease. Its non‑abrasive surface makes it ideal for direct contact with oil paint layers.
Benefits
- Non‑Abrasive Surface: Glassine’s ultra‑smooth finish prevents microscratches on the paint film.
- Moisture Resistance: Its tight fiber structure repels light moisture, reducing the risk of environmental damage.
- Archival Quality: Being acid‑free, glassine will not release harmful acids that degrade paint over time.
Application Tips
- Cut to Size: Trim glassine to cover the entire painted surface plus a 2–3 cm overlap on all sides.
- Lay Gently: Place a single layer directly over the painting face, ensuring no wrinkles or folds touch the paint.
- Secure Edges: Use archival‑quality tape on the back stretcher or frame to keep the glassine in place without contacting the paint.
Acid‑Free Tissue Paper
Overview
Acid‑free tissue is a lightweight, porous paper primarily used as an intermediary layer between the artwork and cushioning wrapping materials.
Benefits
- Breathability: Allows air exchange, preventing moisture buildup that can lead to mold.
- Light Cushioning: Provides a soft barrier that conforms to textured paint surfaces without abrasion.
Application Tips
- Layering: Place acid‑free tissue over the glassine layer to add an extra cushion before using bulkier wraps.
- Multiple Sheets: For heavily impastoed or highly textured works, use two to three sheets to ensure complete surface coverage.
Closed‑Cell Foam (Volara, Microfoam)
Overview
Closed‑cell foam sheets like Volara or Microfoam offer lightweight yet firm cushioning, ideal for protecting frames and canvases from impact.
Benefits
- Shock Absorption: The closed‑cell structure absorbs vibrations and sudden shocks.
- Non‑Abrasive: Smooth on both sides, it will not scratch the paint when the foam is the innermost layer.
- Moisture Barrier: Impermeable to water, protecting against incidental spills or high humidity.
Application Tips
- Bubble Side Up/Down? If using bubble wrap instead, ensure bubbles face outward; for foam, either side is safe.
- Enveloping: Wrap the painting in foam, leaving a 5 cm overlap before adding external wraps.
- Combine with Tissue: Always have tissue or glassine beneath foam to prevent direct contact with the paint.
Bubble Wrap Best Practices
Overview
Bubble wrap is ubiquitous in shipping for cushioning bulk and preventing shifting within a crate or box.
Benefits
- Cushioning Bulk: Fills voids and distributes pressure evenly.
- Cost‑Effective: Readily available in various bubble sizes for different levels of protection.
Potential Risks
- Surface Marks: Direct contact of bubble wrap bubbles against paint can imprint or stick.
- Moisture Trapping: Can trap humidity if used as the only inner layer.
Application Tips
- Outer Layer Only: Always position bubble wrap as the second or third layer over glassine, tissue, or foam.
- Bubble Orientation: Keep bubbles outward to avoid pressure points against the painting.
- Secure Wraps: Use palette wrap (plastic stretch film) to snugly hold the bubble wrap in place without tape touching the painting surface.
Tyvek & Mylar Films
Overview
Tyvek and Mylar (Melinex) are synthetic, inert films offering water resistance, tear resistance, and breathability.
Benefits
- Inert Composition: Does not off‑gas or react with paint layers.
- Long‑Term Storage: Preferred by museums for archival storage due to longevity.
- Pest Barrier: Impermeable to insects and spores.
Application Tips
- Primary Layer: Use Tyvek as the first wrapping layer over tissue/glassine for ultimate protection.
- Replace with Mylar: For high‑value works, especially in fluctuating temperatures, opt for Mylar over Tyvek for added stability.
Pallet Wrap / Palette Wrap
Overview
Similarly named to kitchen plastic wrap, palette wrap is a highly stretchable polyethylene film used to bind layers securely.
Benefits
- Tight Hold: Applies uniform pressure to prevent internal shifting.
- Clear View: Allows quick inspection without removal.
Application Tips
- Start at the Back: Begin wrapping at the rear to ensure the front remains smooth and wrinkle-free.
- Multiple Passes: For larger paintings, make several overlapping passes to build up strength and stability.
Additional Protective Components
Rigid Cardboard or Foam Board
- Prevents Pressure Points: A rigid board over the wrapped surface distributes external force.
- Custom Fit: Cut to exact dimensions or slightly larger with scored edges to fold around sides.
Corner Protectors
- Shock Protection: Foam or plastic corner guards absorb impacts on vulnerable edges.
- Easy Installation: Slip onto frame corners before final wrapping layers.
Silica Gel Packs
- Humidity Control: Include 2–3 packs taped to the back stretcher to moderate RH within the wrap.
Crate Design Considerations for Oil Paintings
Even with impeccable wrapping, an appropriately designed crate is essential to guard against extreme shocks, temperature fluctuations, and handling errors.
Material Selection
- Kiln‑Dried Pine or Plywood: Non‑warping, sturdy, and widely available.
- Internal Bracing: Cross‑members and cradle systems to immobilize the painting within.
Environment Control
- Insulated Liners: Foam or corrugated plastic liners within the crate walls buffer temperature swings.
- Sealed Construction: Gasketed edges or tape‑seal seams to exclude dust and pests.
Handling Features
- Skids & Feet: Elevate the crate off the floor to avoid water damage and ease forklift access.
- Labeled Handling Instructions: “This Side Up,” “Fragile,” and pictograms reduce mishandling risks.
