The packaging of a work of art: When travel threatens the masterpiece

01When transport becomes an invisible threat

Every year, thousands of artworks crisscross the globe for exhibitions, auctions, or loans between museums. In 2023, the art transport market generated $1.2 billion, according to the TEFAF report. Yet 30% of insurance claims involve damage sustained during transit—and in 80% of cases, inadequate packaging is to blame. The Centre for Research and Restoration of the Museums of France (C2RMF) has recorded over 200 damaged artworks between 2010 and 2020 due to acidic materials, humidity, or poorly cushioned shocks.

Take the case of Klimt’s Portrait of Adele Bloch-Bauer, acquired by Ronald Lauder for $135 million in 2006. During its transport to the Neue Galerie in New York, the work endured brutal fluctuations in temperature and humidity. The result: microfissures in the gold leaf, requiring $1.5 million in restoration. "A poorly packaged artwork can lose up to 50% of its value in a matter of hours," confirms an expert from the Art Loss Register. And some mistakes are simply irreparable.

02The materials that save—or destroy

Behind every successful packaging lies a carefully selected alchemy of materials. Bubble wrap, for instance, is a classic—but beware of its use. "Standard polyethylene generates static electricity, which attracts dust and can damage paint layers," explains Marie-Laure Desjardins, a restorer at the C2RMF. For sensitive works, like Degas’ pastels or Seurat’s charcoals, professionals now favor Marvelseal, a barrier film that insulates the artwork from humidity while allowing the support to breathe.

Wooden crates remain essential for heavy or fragile works. But their construction follows strict rules: insect-treated wood (ISPM 15 standard), high-density foam blocks to absorb shocks, and sometimes even integrated temperature and humidity sensors. "We use custom crates for each artwork, with acid-free certified materials," says a logistics manager at Galerie Perrotin. For Anish Kapoor’s Cloud Gate in Chicago, transporters designed a climate-controlled crate capable of maintaining a constant temperature within ±2°C.

Conversely, some materials are absolutely forbidden. Newspaper, for example, transfers its ink and yellows the support. Even "archival" adhesive tape leaves sticky residues that can peel off paint. And non-breathable plastic bags create a greenhouse effect, encouraging mold growth. "A common mistake among amateur collectors: wrapping a work in stretch film, as you would a piece of furniture," laments a curator at the Musée d’Orsay. The result? Warped canvases, flaking pigments, and impossible restorations.

03The secret protocol of museums

Behind every artwork loan lies a meticulously choreographed logistical ballet. When the Louvre lends Delacroix’s Liberty Leading the People to an international exhibition, the process begins six months in advance. First, a team of restorers examines the work from every angle: the stability of the support, the condition of the paint layer, its sensitivity to light. Then, a custom packaging is designed, with materials tested in the laboratory. "We use SpotSee sensors that record shocks during transport," explains a loan manager at the museum. "If the artwork experiences acceleration greater than 2G, the insurance is automatically alerted."

For works on paper, like Picasso’s prints or Matisse’s drawings, the standards are even stricter. "Artworks must travel flat, in Mylar polyester envelopes, with an acid-free mat," details a curator at the BnF. The temperature must remain between 18 and 22°C, and relative humidity between 45 and 55%. "Above 60% humidity, paper deforms and mold appears within 48 hours," he notes. For old photographs, like those by Man Ray, the packaging must even be opaque to prevent any light exposure.

The most advanced museums, like MoMA or the Centre Pompidou, now use 3D modeling software to design custom packaging. "For Picasso’s Guernica, we simulated the vibrations of air transport before approving the crate," recalls a former logistics manager at the Reina Sofía. The painting, measuring 3.5 by 7.8 meters, traveled rolled around a giant cylinder, in a climate-controlled crate equipped with shock-absorbing suspensions.

04The mistakes that cost millions

Some disasters have become cautionary tales in the world of conservation. In 2004, The Scream by Munch was stolen from the Oslo museum. When police recovered it two years later, the thieves had cut the frame to make transport easier. The result: tears in the canvas and irreversible loss of pictorial material. "An artwork should never be separated from its frame during transport," insists an art insurance expert. "The frame is part of the work, and it absorbs some of the shocks."

Another example: Van Gogh’s Sunflowers, loaned by the National Gallery in London in 1990. During transport, the work was wrapped in newspaper. "The ink transferred onto the canvas, creating yellowish stains that required months of restoration," recounts a curator. Today, the museum exclusively uses acid-free tissue paper, certified to ISO 18916.

Sometimes, mistakes stem from an excess of caution. In 1981, the Venus de Milo was loaned to Japan. To protect her, transporters packed her in a wooden crate lined with damp straw. "The straw released moisture, causing oxidation of the marble," explains a Louvre restorer. The resulting black stains are still visible today.

05Contemporary art: a permanent challenge

With contemporary art, the challenges multiply. How do you package a Damien Hirst work made of formaldehyde? How do you transport a Yayoi Kusama installation with its thousands of mirrors? "Every work is a unique case," confirms a logistician at Hauser & Wirth gallery. For The Physical Impossibility of Death in the Mind of Someone Living—Hirst’s shark—the team designed a sealed crate filled with nitrogen to prevent oxidation.

Interactive works, like Bruce Nauman’s neon pieces, pose another problem: they require a power supply during transport. "We use lithium-ion batteries and uninterruptible power supplies to prevent power cuts," explains a manager at Tate Modern. For Cloud Gate, Anish Kapoor demanded that the sculpture travel under controlled atmosphere, with real-time monitoring.

Unstable materials, like Louise Bourgeois’ resins or Robert Morris’ latex, impose additional constraints. "Latex ages poorly and becomes sticky over time," explains a MoMA curator. "It must be transported in climate-controlled packaging, with silica gel to absorb moisture." For Maman, Bourgeois’ famous spider, transporters designed a custom crate with high-density foam blocks to protect the fragile legs.

06Who is responsible when a work is damaged?

In case of damage, the question of responsibility is crucial. Transport contracts generally include strict clauses: declared value, handling conditions, liability in case of negligence. "If a work is damaged because it was packed with newspaper, the insurance may refuse to cover the costs," explains an art law specialist.

In 2015, Sotheby’s was ordered to pay $4 million for damaging a Rothko painting during transport. The work, valued at $8 million, had been packed without climate protection. "Insurers like Lloyd’s of London now require proof of professional packaging to cover artworks," notes a broker.

For loans between museums, contracts generally include a "reversibility clause": if the work is damaged, the lender can demand restoration at the borrower’s expense. "When the Louvre lends a work to the Metropolitan Museum, we send a team of restorers to supervise the packing and unpacking," explains a loan manager. "It’s a matter of trust, but also of responsibility."

07Toward sustainable packaging?

The art market generates tons of packaging waste every year. According to the Art Basel 2023 report, 80% of crates and materials end up in landfills. Yet solutions are emerging. Some galleries, like the Fondation Cartier, now use mushroom-based packaging (mycelium), which biodegrades in 30 days. Others, like Thaddaeus Ropac gallery, rent reusable crates from specialized companies.

"We’re working on algae-based foams that dissolve in water after use," explains a materials engineer for the art sector. "The goal is to reduce the carbon footprint without compromising the safety of the works." For sensitive works, like pastels or drawings, some museums are testing Tyvek packaging, a durable and recyclable material.

But the real challenge remains cost. "Eco-friendly packaging can be up to 30% more expensive than standard packaging," admits a logistician. "And for high-value works, safety remains the priority." Yet the pressure is mounting. In 2024, the Palais de Tokyo announced it would only accept recyclable packaging for its loans. "It’s a question of ethics, but also of survival," explains its director. "The public wouldn’t understand if we sacrificed the planet to transport a work of art."

08What you need to know before packing an artwork

If you own an artwork, a few simple rules can prevent disasters. First, never use acidic materials: newspaper, uncertified cardboard, standard adhesive tape. Next, protect the surface with a barrier film (Marvelseal) or acid-free tissue paper. For paintings, avoid direct contact with the canvas: use foam blocks to keep the work suspended in its crate.

For works on paper, transport them flat, in polyester envelopes, with an acid-free mat. Control the climate: a temperature between 18 and 22°C, and humidity between 45 and 55%. For sculptures, use adjustable straps to prevent movement during transport.

Finally, call in professionals for valuable works. Galleries and museums work with specialized transporters, like Hasenkamp or Crozatier, who know the standards and protocols. "A poorly packed artwork is like a house without a roof," sums up a curator. "Sooner or later, the rain gets in."
