Suppliers and guide to selecting preservation materials
This guide aims to provide information to help you select appropriate, safe enclosure materials to store and preserve your personal collections. A list of suggested suppliers of preservation materials is also provided.
Some things to consider
A good approach to housing your collections is to provide several layers of protection by first placing individual objects into sleeves or envelopes, then into suitable boxes or folders.
Always be cautious when purchasing storage material. Many commercially available enclosures are labelled 'archival' or 'acid-free'. However, some of these items may contain lignin, dyes, sizing agents, coatings, plasticisers, or other harmful additives. Always ask for product specifications and if in doubt consult a conservator.
Never use enclosures made from unprocessed wood pulp paper, glassine, or polyvinyl chloride (PVC). Never laminate objects that are precious to you as the process is irreversible and deteriorates with age. The process itself is also harmful to the object as it contains heat, adhesives, and pressure.
Paper or Plastic archival enclosures?
- There are two main materials used for archival enclosures: paper and plastic.
- The choice between paper and plastic enclosures should be based on the type of object being housed and its condition, the anticipated amount of use, financial resources, and environmental storage conditions.
- Items that are used frequently can be abraded by repeated removal from and insertion into paper enclosures, thus plastic may be more suitable as the object can be viewed in-situ. In areas of high humidity, paper enclosures should be used as they allow greater airflow, thus preventing the creation of microclimates within storage enclosures.
- Material that may potentially off-gas harmful acidic by-products (e.g. cellulose acetate and nitrate film) should also be housed in paper enclosures, as it allows air exchange thus minimising detrimental build up of acids.
- Use the table entitled Selecting safe enclosure materials to help make the right selection.
- Always make sure the method of storage selected is reversible so that you can safely remove your collections without damaging them if you notice any problems.
