1、Features:
Under the same evaporation conditions, the larger the coating thicknessδ, the smaller square resistance (Ω/□) , the smaller the resistance R, the greater the load current, while the worse self healing properties.
Al metallized film has a better over-current performance.
Al metallized film has a better moisture resistance.
2、Types of Metallized Layer：
Margin size（mm）：1.0±0.5、1.5±0.5、2.0±0.5、2.5±0.5、3.0±0.5、4.0±0.5、5.0±0.5
Coating square resistance（Ω/□）：1.5±0.5、2.0±0.5、2.5±0.5、3.0±1

6、Packing：
7、 Storge：
1、Metallized film should be stored in its original package until its use with temperature 5 ～35℃and humidity less than 85%RH.
2、Metallized layer is easily oxidized when exposure to moisture. Therefore, the film should be used as soon as possible when opened.
3、The recommended temperature is 15 -25℃with humidity less than 60%RH after the package is open.
4、With original sealed package, and stored in the above mentioned conditions, the storage time can be as following:
Al metalized Film: 12 months from the delivered date
Al/Zn Alloy metalized Film: As Zn is relatively unstable, preservation period depends on the resistance of the film：
Less than 10 Ohms: 6 months (from delivery date)
10 Ohms to 15 Ohms: 3 months (from delivery date)
15 Ohms: 1months (from delivery date)
