由 caicai8478 I. Core Principles and Risk Assessment
A. Italian Conservation Philosophy
Following the core principle of “prevention is better than cure,” this approach combines traditional craftsmanship with modern materials science. Each artwork is considered a unique individual, and packaging solutions must be based on a comprehensive “Condition Report” and “Travel Risk Assessment.”
B. Risk Assessment Matrix
Pre-transport assessments include:
Item fragility: Materials (canvas, wood, marble, glass), structure, age, current restoration status
Journey risks: Distance, mode of transport, number of transshipments, crossing climate zones, potential vibration and shock
Destination environment: Destination climate, exhibition hall conditions, expected exhibition period
II. Customized Cushioning Packaging System
A. Multi-Layer Protective Structure (“Onion” Packaging Method)
First Layer: Intimate Protection (Direct Contact)
Acid-Free Cotton Paper Wrapping: Uses pH 7.5-8.5 treated cotton paper.
Sulfur-Free Thin Cotton Paper Pleated Filling: Creates a flexible transition between delicate surfaces (such as gilded frames) and rigid support.
Reversible Fixing Method: Uses only acid-free tape, cotton straps, or unbleached plain weave fabric.
Second Layer: Cushioning and Support Layer (Customized Inner Packaging)
Sculptures and Three-Dimensional Works:
Sculpted Foam: High-density polyethylene foam (60-80 kg/m³) CNC-cut according to the artwork’s contours.
Vacuum-Formed Plastic Sleeve: Customized sleeves using PETG or copolyester for extremely delicate surfaces.
Suspension System: Internal spring suspension allows the artwork to “float” within the case, isolating it from external vibrations.
Paintings and Two-Dimensional Works:
Rigid Support Board: Honeycomb aluminum panel or museum-grade corrugated cardboard (compliant with PAT testing).
Corner Protection: Uses molded foam or Corner. Lok™ Patented System
Abrasion-resistant separation layer: Silicone-coated cellophane or Teflon film
Glass and ceramics:
Pre-stretch wrapping: Using adjustable tension Cling Film™ wrapping film
Gel padding: Silicone or polyurethane gel padding for perfect fit to irregular surfaces
Segmented packaging: Components are packaged separately and then assembled and secured
Third layer: Structural outer shell (custom shipping case)
Material options:
Climate Control Crates: Plywood + aluminum frame with built-in insulation
Traditional Italian wooden crates: Poplar or pine, mortise and tenon joints, prohibiting direct contact of artwork with nails
Internal structure: Honeycomb-shaped cushioning compartments, isotropic support
Sealing system: Using neoprene or silicone sealing strips to achieve IP54 protection rating
B. Dedicated cushioning material library
Material Density Best Use Italian supplier examples
Ethafoam™ 22-45kg/m³ General purpose cushioning Arteinmovimento
Reglass™ 30kg/m³ Ultra-fine surface Goppion Bubble Film N/A Lightweight Filler, Protector Archival Corrugated Acid-Free Flat Artwork Separator, FAZI

Backup power supply and lighting
IX. Cost Estimation Reference
Protection Level | Packaging Cost (as a percentage of artwork’s estimated value) | Typical Transportation Time | Applicable Artwork Type
Basic Level | 0.5-1% | Domestic/Short Distance | Modern Reproductions, Decorative Artwork
Professional Level | 1-3% | International/Medium Distance | 19th-20th Century Originals, Important Sculptures
Museum Level | 3-8% | Global/Long Distance | Old Masters Works, National Treasures
Ultimate Protection Level | 8-15%+ | Special Missions Frescoes, Extremely Fragile Works
X. Summary of Italian Best Practices
Respect for Material Characteristics: Every material (wood, paint layers, plaster) has its own “memory” and physical properties.
Simulate a Static Environment: Excellent packaging should make the artwork “feel” like it’s still on the museum wall.
Full Traceability: Every action should be recorded from studio to destination.
Expert Team: Packers, conservators, logistics experts, and insurance assessors collaborate in planning.
Cultural Responsibility: Transporters are not just logistics providers, but temporary guardians of cultural heritage.
This guide integrates the standard operating procedures of the Uffizi Gallery, Brera Gallery, and major Italian art transport companies (such as C.R.C., Hasenkamp, Moby). Specific plans need to be adjusted according to the actual artwork and transport requirements.
