Storage and shelf life


This film should be stored in a low temperature dry place, the best storage conditions are temperature 10℃ ~ 23℃, relative humidity 30% ~ 65%. Should be strictly avoided in high temperature, high


Stored in wet, radioactive and chemical gases, avoid to store in the same room with processing liquid medicine, and should be used within the validity period, product shelf life of 30 months.


Matters needing attention


1. The film stored at low temperature should be taken out 2 hours in advance before use, and placed at room temperature for more than 2 hours to ensure the temperature of the film and the use environment


The temperature balance is consistent, and then open the film packaging, in order to avoid the formation of water vapor on the surface of the film caused by the adhesion between the films and affect the film picture effect,


To ensure the normal use of film.


2. The film should be unsealed, loaded and rinsed under the safety lamp. The film should not be exposed for too long under the safety lamp


Contaminated film, film should be handled with care to avoid friction. After unsealing, the film should be used up as soon as possible, and the unused film should be sealed according to the original package.
