Storage Metallized film should be stored in its original package with temperature 5 - 35ºC and humidity less than 85%RH before using. Metallized layer is easily oxidized when exposure to moisture. Therefore, the film should be used as soon as possible when opened. The recommended temperature is 15 -25ºC with humidity less than 60%RH after opening. With original sealed package, and stored as mentioned above, the storage time can be as following: Al metallized film: 12 months from the delivery date. Al/Zn Alloy metallized film: As zinc is quite unstable , the storage period (from delivery date) depends on the resistance of the film: ≤10 Ω/: 6 months 10 ~30Ω/: 3 months
>30Ω/: 1month
