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 5 - 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
