The work aims to explore the influence of environmental temperature and humidity on deformation of aluminized paper, and obtain the best ranges of storage temperature and humidity of the aluminized paper. Three kinds of aluminized papers were respectively cut into two different sizes, and the paper deformation experiments were carried out by constant temperature humidity chamber. In each setting conditions of temperature and humidity, the sizes of large paper and moisture content of small paper were respectively measured in the process of moisture absorption and dehumidification. First, in order to calculate the paper stretch ratio, the standard paper sizes were obtained in 55%RH conditions through the correlation modeling analysis of environmental humidity and paper size. Second, the range of paper stretch ratio was calculated according to the range of referenced registering accuracy. The humidity range was achieved through constructing the correlation model of paper stretch ratio and humidity. Third, the correlation model was established between water content and environmental temperature and humidity. Finally, through the correlation analysis of paper stretch ratio and water content, the temperature range corresponding to the referenced registering accuracy was gained by applying the humidity range to the water content model. The research results showed that, under the conditions of meeting the control range of registering accuracy of three kinds of papers, the standard control range of the workshop temperature should be 20.4~26.3 ℃, and the standard control range of relative humidity of the workshop should be 53.9%~58.0%. The deformation of aluminized paper can be well controlled through the study on the influence of environmental temperature and humidity on the deformation of aluminized paper.
