Packing:

• Film rolls are packed in plastic bags, vacuumed and put into desiccant for heat sealing.
• The Bags are marked with type labels, mark thickness width, free margin width and resistance.
• The bags are packed in carton cases.

The cartons are wrapped by wooden cases or reinforced carton.
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/square: 6 months
10 ~30Ω/square: 3 months
>30Ω/square: 1month
