Zn-Al Metallized BOPP Plastic Film For Capacitor Use
Product Description
The metallized film is to vapor-deposit zinc and aluminum on the surface of the film in a vacuum state.The material has large dielectric constant, high insulation resistance, good heat resistance and good tensile properties, and is suitable for making metallized polypropylene film capacitors.
Product Parameters

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
Our Advantages
Core Advantages
