Abstract
Biaxially oriented poly(vinyl alcohol) film (BO-PVA film) is a transparent synthetic resin film which is 15mu thick and composed of two layers of polyvinylidene chloride sandwiching one layer of poly(vinyl alcohol). Because BO-PVA film has excellent gas-tight and moisture proof characteristics, it is ideally suited for wrapping and protecting objects from high humidity environments. Evcavated materials if kept in normal atmospheric conditions, undergo various kinds of deterioration. The author believes, however, that excavated materials can be preserved in almost the same condition as in their buried environments if they are covered with BO-PVA film as soon as possible at the site excavation. In addition, BO-PVA film has proven to be an effective moisture proof shield for oil paintings, books and other cultural properties. See also AATA 18-945 for Part I.
