What makes paper unstable?
Paper breaks down chemically and physically as it ages. Its chemical degradation creates products that can contaminate and react with other records. Aged paper is more susceptible to damage when handled.
The condition of paper over time is determined by the quality and type, how it has been made, what is in it and how it has been used, stored and handled.
Archival quality paper will undergo little or no change in its properties.
Recycled content is measured as a percentage of the paper’s weight. This may not be detailed on the product label, making it difficult to gauge its durability and longevity.
Recycled paper may be adequate for records of short-term retention, drafts and other casual use.
Thermal paper is highly unstable. The text can fade within months and may not last longer than 5 years. We do not recommend using thermal paper. Records created on this paper should be copied to a better paper or scanned electronically.
Permanent paper must meet certain standards and specifications. Paper advertised as lasting 100 years, ‘durable’, ‘acid-free’, ‘lignin-free’ and ‘buffered’ does not necessarily meet these relevant standards. Archival paper will be watermarked or have packaging labelled with a statement of compliance with the relevant standard(s).
AS 4003-1996: Australian Standard for Permanent Paper governs the permanence and durability of paper and how it is stored. It defines permanent paper as paper ‘which during long term storage in libraries, archives and other protected environments will undergo little or no change in properties that affect its use’.
The optimal climate-controlled conditions stipulated in AS 4003-1996 will not guarantee the continued strength of paper.
For records with a retention period of 30 years or more, the paper is required to meet the National Archives of Australia’s (NAA) technical specification for archival paper.
These specifications require the paper to have increased pH levels and lignin-free content. Paper that is compliant with the NAA specification will have the following NAA registered trademark.
ISO 18916:2007 Imaging materials–Processed imaging materials–Photographic activity test for enclosure materials applies to paper (and other materials) to use to store photographic materials.
The type of paper you should use depends on the record’s retention requirements, use and likely storage conditions.
