Custom protective covers can help museums reduce dust deposition, incidental handling exposure and minor splash risks around stored collections. The most effective cover is not simply a piece of material cut to size: it is a specification that considers the object, storage environment, staff access and the complete finished construction.
This guide explains the decisions to make when specifying custom Tyvek covers for museum storage. For an overview of the material and its limitations, begin with our practical guide to Tyvek covers in museum and archival storage.

Start with the storage risk—not the cover
Define the main problem before choosing a design. Common priorities include reducing dust, limiting incidental contact, providing a light barrier, improving identification or protecting equipment during movement between storage and work areas. A cover should complement appropriate enclosures, environmental management, pest control, leak prevention and safe handling procedures.
For sensitive objects, direct-contact applications or unusual environments, involve a qualified conservator in the specification.
What will the cover protect?
Record the object or storage system, its materials, sensitivity, condition and normal position. Museum cover projects may involve:
- collection objects on open shelving
- archival boxes and primary enclosures
- mobile shelving bays and cabinets
- framed works and art-storage racks
- garment and textile systems
- trolleys, equipment and handling aids
- large or irregular objects
Clarify whether the cover will touch the object or only surround its support or enclosure. That distinction can affect material selection, seams and clearance.
Select material for the application
Tyvek is a non-woven high-density polyethylene material valued in many collection-care contexts for its low weight, tear resistance and low-lint surface. Different grades and styles behave differently. A product used for construction, packaging or disposable clothing is not automatically appropriate for a museum application.
The specification should identify the selected Tyvek style and any other components, including thread, zips, hook-and-loop fasteners, windows, labels and reinforcement. Finished performance depends on the entire cover—not only the base sheet.
Specify the fit accurately
Provide maximum external width, depth and height in millimetres. Include handles, hinges, latches, wheels, brackets and other protrusions. A practical allowance is usually needed so staff can remove and refit the cover without catching corners or applying force.
Do not add an arbitrary allowance to your figures. Supply the true dimensions and explain the handling routine so the manufacturer can discuss suitable clearance. Use our step-by-step custom cover measurement guide to prepare dimensions, sketches and photographs.
Plan access and staff workflow
A cover that obstructs normal work may be removed and not replaced. Identify how frequently staff access the item and which components need to remain available. Options may include:
- front or side flaps
- zip openings
- openings around fixed handles
- inspection or identification windows
- label pockets
- split designs for large equipment
Mark the front face, opening direction and location of every access point on photographs or a labelled sketch.
Consider seams, closures and openings
Every seam or opening changes how the finished cover performs. The cover should not be described as waterproof simply because Tyvek resists water. Zips, stitched seams, windows and access gaps may allow moisture entry. Ask how the proposed construction responds to the risks identified for your storage area.
Closures should also be easy for staff to operate without placing pressure on fragile parts. Avoid features that could catch on an object or introduce unnecessary abrasion.
Make identification straightforward
Collection staff should be able to identify a covered item without unnecessary handling. Provide the required label size, orientation and viewing position. Consider whether a window, external label pocket, printed identifier or barcode access is appropriate for the workflow.
Identification features should be placed where they remain visible in the object's normal storage position.
Decide between standard and custom sizes
Standard fitted covers can be efficient for repeated box formats or identical equipment. Custom designs are better suited to unusual objects, shelving systems, large equipment or applications requiring access features.
For repeated custom sizes, consider approving one sample before full production. A trial fit allows staff to confirm clearance, orientation, closures and label placement.
Assess the supplier's specification process
A useful quotation process should clarify:
- object and storage-system dimensions
- selected material and components
- quantity for each size
- fit and clearance
- access and closure details
- label or window requirements
- production tolerances
- lead time and delivery location
Ask for assumptions to be recorded so that both parties are reviewing the same design before production begins.
Information to include in your enquiry
- Organisation and contact details
- Description of each object or storage system
- Maximum dimensions in millimetres
- Quantity required
- Front, side, rear and detail photographs
- Handling and access frequency
- Main risks the cover should reduce
- Preferred openings, closures and labels
- Delivery postcode and required timing
