MPPZn/AlH Slope Metallized Film

Coating a thin Al/Zn layer on the surface of plastic film, will get high self-healing Al/Zn metallized film for capacitor use.
The prominent feature of metallized film is its self healing ability. That is, when somewhere is breakdown, short-circuit current can make the film around the breakdown area melting and evaporation to recover its insulation property. Thus significantly reduce the impact on the breakdown strength by conductive defects and weakness in paper or film, thereby improving the working field.
Generally the thickness of the metal layer is 5nm-50nm, but on the international it can be 1nm-100nm. In terms of heat resistance, 1nm-100um is preferred, when taking electric properties into consideration of electric properties, 5nm-50nm is more preferred.

Packing

Roll films are packed in vacuum plastic bag

Bags are marked with lables of types

The bags are packed in carton cases

The cartons are wrapped in wooden cases or reinforced carton  

 Storge

Metallized film should be stored in its original package and be used with temperature 535℃ and humidity less than 85%RH.

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

The recommended temperature is 15 -25℃with humidity less than 60%RH after the package is open.

With original sealed package, and stored in the above mentioned conditions, the storage time can be as following:

Ø Al metalized Film: 12 months from the delivered date.

Ø Al/Zn Alloy metalized Film: As Zn is relatively unstable, preservation period depends on the resistance of the film

ü Less than 10 Ohms: 6 months (from delivery date)

ü 10 Ohms to 15 Ohms: 3 months (from delivery date)

ü 15 Ohms: 1month (from delivery date)
