Shipping artwork internationally requires far more than simple bubble wrap and a cardboard box. Paintings, sculptures, antiques and collectibles are sensitive to impact, vibration, moisture, temperature, and improper packing materials. The wrong technique can cause cracking, warping, scratches, or even complete artwork loss.
As specialists in fine art logistics and fragile cargo shipping, CalcoCargo has over 15 years of experience packing, crating and transporting high-value art for galleries, collectors, auction houses and private clients worldwide. This comprehensive guide explains exactly how to prepare artwork for safe international transport.
1. Why Proper Packing Is Critical for Artwork
Art is vulnerable to multiple risks during transit:
- Shock and vibration
- Pressure changes during flights
- Humidity and temperature fluctuations
- Mishandling during loading
- Abrasion from poor packing
- Moisture seepage
- Canvas tension changes
Standard couriers are not trained to handle artwork, which is why proper museum-level packing is essential before international shipping.
2. Prepare a Clean, Safe Workspace
Before packing:
- Clean the workspace
- Lay soft padding on the table
- Wear cotton or nitrile gloves
- Ensure the area is dust-free
Artwork should never be handled with bare hands due to oil transfer.
3. Use Museum-Grade Protective Materials
Only archival or non-reactive materials should be used. Avoid newspaper, cling wrap, or cheap bubble wrap.
Correct professional materials:
- Glassine paper (protects against moisture and abrasion)
- Acid-free tissue paper
- Bubble wrap (non-abrasive, smooth type)
- Polyethylene foam sheets
- Foam corner protectors
- Rigid backing board
- Shock-absorbing foam blocks
- Poly-coated vapor barrier film
These materials prevent paint sticking, chemical reactions, moisture absorption and surface damage.
4. Step-by-Step: Packing Paintings for International Shipping
Step 1: Surface Protection Layer
Wrap the artwork with glassine paper or acid-free tissue.
This prevents the wrap from touching the painted surface and protects against humidity.
Step 2: Add Cushioning
Wrap the artwork in smooth, non-sticky bubble wrap.
Add:
- foam corner protectors
- two layers of wrap
- a rigid board across the face for support
Step 3: Secure the Edges
Tape only the outer bubble wrap — never tape directly onto the glassine or artwork.
5. Packing Sculptures, Antiques and 3D Artwork
Sculptures require zero movement inside the crate.
Key techniques include:
- foam cavity molds
- bracing blocks
- multi-layer cushioning
- rigid side supports
- double-boxing for extra protection
Irregular shapes must be custom fitted to the crate interior.
Large or heavy sculptures often require internal suspension systems to absorb impact.
6. Build a Custom Wooden Crate for Maximum Protection
A professional art crate is essential for international transport.
What a museum-grade crate includes:
- 12–20mm plywood walls
- vapor barrier lining
- polyethylene foam interior
- shock-absorbing mounts
- foam spacers
- insulated internal padding
- screw-down or bolted lid
- edge bracing
- forklift-safe base (optional)
A crate prevents shifting, reduces vibration, and protects against drops or compression during handling.
CalcoCargo provides secure crating services tailored to each artwork’s dimensions and fragility.
7. Add Humidity, Temperature & Shock Protection
Artwork is sensitive to environmental changes during flights and ocean transport.
Add the following inside the crate:
- Desiccant packs to control humidity
- Vapor barrier film to prevent moisture seepage
- Shock/tilt indicators on the crate exterior
- Silica gel packs for long-distance sea freight
This helps preserve the artwork through long journeys and climate shifts.
8. Label the Crate Correctly
Proper labels ensure safe handling.
Recommended labels:
- FRAGILE — HANDLE WITH CARE
- THIS SIDE UP
- DO NOT STACK
- KEEP DRY
Attach the packing list and commercial invoice in a sealed pouch.
9. Choose a Specialist Art Shipping Company
The safest packing is only effective if paired with professional handling.

- white-glove pickup
- airport supervision
- fine art air freight

10. Always Insure Your Artwork
Even with perfect packing, insurance is essential.
We recommend:
- All-risk cargo insurance
- Coverage for packing, transport, flight, handling, and delivery
- Declared values based on market replacement or appraisal
Insurance protects you against unforeseen events beyond your control.
