Temperature and humidity requirements

General Paper at 38 ℃ or above, its intensity decreased significantly, the Treasury within the temperature to 18 ~ 25 ℃ is appropriate, indoor (paper base) temperature reached 39 ℃, air cooling measures should be taken to prevent the deterioration of paper embrittlement.

     In order to better ensure the quality of paper, storage of paper is best able to grasp the relative humidity of 60% -70%. Winter and spring, too dry, too wet in summer, as well as poor ventilation, light exposure, dust and harmful gases such as stolen goods, will affect in varying degrees of performance and quality of paper, warehouse management personnel shall be paid to these factors.
