=Storage Materials=
==Purpose==
Storage materials are those materials used to wrap or support stored collections. These are the materials in direct contact with the collections. Storage materials provide collections with support, especially for moving and handling, and offer an additional layer of protection from environmental hazards.
==Factors to consider==
*All materials that are used in contact with stored artifacts should be archival-quality materials that are not harmful to these objects.
::Non-buffered, neutral pH papers and boards can be safely used for all textile collections and are recommended for objects with protein fibers.
::Buffered papers and boards are generally safe to use with cellulosic collections but have been associated with color changes in some dyes and with corrosion of metals.
*The surface characteristics of the artifact to be stored can affect the choice of storage materials. For some artifacts, a smooth surface is preferable. For others, some friction between the object and the storage material can be desirable.
*The size, shape, construction, and condition of the object will influence the selection of the storage material. The storage material chosen must provide sufficient support to the object in storage. Ideally, this support will also be sufficient for moving the object from storage. Alternatively, an auxiliary moving support must be provided. See also Storage Methods.
==Materials to Avoid for Storage Supports or Containers==
Table 3: Materials to Avoid for Storage Supports or Containers
Material 	Volatile/Migrating Products
Fabrics 	
    Flame resistant fabrics 	formaldehyde
    Nylon-6 	acetic acid
    Permanent press and crease-resistant fabrics 	formaldehyde
    Pest-proofed fabrics 	formaldehyde
    Wool and wool felts 	sulfides; attracts insects
    Sulfur-containing dyes 	sulfides
Papers 	
    Newsprint 	
    Kraft paper 	
    Unbuffered blotter paper 	acid degradation products
    Glassine 	
    Tissue paper; blue tissue 	
    Any papers that are not acid-free or buffered	
Paper Products

==Materials that are Considered Safer for Textile Storage Containers or Supports==
Table 4: Materials Considered Safer for Textile Storage Containers or Supports
Fabrics
    Cotton - pre-washed, desized
    Linen - desized
    Polyester - not from recycled plastics but virgin polyester.
    Reemay, other spunbonded needlefelts, etc. Make sure the product has not been manufactured with adhesives.
    Any dyed fabrics must be washfast.
Foams
    Polyethylene - Ethafoam®, Nomaco Backer Rod HBR® Type C, Volara®, Plastazote®
Paper Products
    Unbuffered, neutral pH blotter paper
    Acid- and lignin-free corrugated board
    Unbuffered, neutral pH acid-free tissue
    Buffered acid-free tissue and paper (safe for cellulosics only)
Plastics
    Polyester film - Mylar®
    Virgin polyethylene film and sheets. (Not all polyethylene film is archival-quality; it may contain antioxidants, processing films, etc.)
    Polypropylene - corrugated polypropylene/polyethylene copolymer sheet such as Cor-X®, Coroplast®, and PolyFlute®
    Polystyrene
    Polyolefin - Tyvek®
    Polycarbonates
    Polyacrylonitrile
    Poly(methyl methacrylate) - Plexiglas®, Lucite®
