The shrinkage of acetate films is often take place during storage however why this happens easily is not clearly. This article discusses that temperature and humidity of storage effects on acetate films the result is that acetate film is kept in low humidity for long time, shrinkage will take place. The researchers analyzed the situation that the lengths of different kinds of acetate film had changed with different treatment and tried to find some pattern which could explain how the length of film changed. The researchers try to find a way to recover the shrinkage film through experiment 4 recovering treatment have variation affection on shrinkage recovering as well as the density of film. From this research, we also know recovering of film will finish quickly.
