Ø Film rolls are packed and heat-sealed in vacuum plastic bags with desiccants inside.

Ø The Bags are marked with type labels, mark thickness width, free margin width and resistance.

Ø The bags are packed in carton cases.

The cartons are wrapped by wooden cases or reinforced carton.

Ø Metallized film should be stored in its original package with temperature - 35 and humidity less than 85%RH before using.

Ø Metallized layer is easily oxidized when exposure to moisture. Therefore, the film should be used as soon as possible when opened.

Ø The recommended temperature is 15 -25 with humidity less than 60%RH after opening

Ø 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
