Packaging materials protect your archive and collections from harmful external influences such as light, air pollution and moisture. The quality of your packaging materials largely determines how long your archive and collections will survive. | Packaging materials protect your archive and collections from harmful external influences such as light, air pollution and moisture.

This significantly delays the acidification process, but please note there are some exceptions! Blueprints, for example, must be stored in inert packaging.
