4.8μm Electronic Capacitor Grade Metallized Dielectric Plastic Polypropylene Film
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.

Packing & Storage
(1) Film rolls are packed and heat-sealed in vacuum plastic bags with desiccants inside.
(2) The bags are marked with type labels.
(3) The bags are packed in carton cases.
(4) The cartons are wrapped in wooden cases or reinforced carton
(1)Metallized film should be stored in its original package with temperature 5~35ºC and humidity less
than 85%RH before using.
(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 15-25ºC with humidty less than 60%RH after opening.
(4)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:
<=10Ω/Square:6 months
10-30Ω/Square:3 months
>30Ω/Square:1 month
