Metallized polypropylene film for electrical appliances can be coated with a very thin plastic film on its surface. Metallised polypropylene film will melt under high vacuum melting and the evaporation of the upper. Metalized polypropylene film is the main raw material for thin film batteries. Anhuisaifu’s metallised polypropylene film is a top-tier solution designed specifically for the capacitor industry. Engineered with precision, this high-quality metallised polypropylene film is metallised to enhance its electrical properties, making it an ideal choice for manufacturing capacitors that demand reliability and performance. Its superior dielectric strength and thermal stability ensure long-lasting durability and efficiency in a wide range of applications. Whether for power, lighting, or electronics, Anhuisaifu's metallised polypropylene film stands out as a premium material that meets the rigorous standards of today’s capacitor manufacturers.

Types of Polypropylene Metallised Film

Features of Metallised Polypropylene Film

  • Base Film

    Biaxially Oriented Polypropylene film (BOPP film).

  • Melt, Evaporate And Precipitate Material

    Melt, evaporate and precipitate high-purity aluminum or zinc on BOPP base film under a high vacuum, and form a very thin metal layer on the surface of BOPP base film.

  • Self-healing Effect

    It has a self-healing effect. After the local breakdown of metallized film medium, it instinctively recovers to the electrical performance phenomenon before breakdown.

  • Margin

    Margin refers to the requirement of actual capacitor production. The blank insulating strip (strip) formed by covering the edges or middle of one or both sides of the metallized film without metal evaporation is called the margin, and its width is called the margin.

  • The Square Resistance

    The resistance value of the metal layer on the metallized film of square resistance in the unit square area is called the square resistance, which is expressed in Ω/□. Generally, the square resistance is used to represent the thickness of the metal coating.

  • Thickness and Width

    Thickness: 2um - 12um

    Width: according to the customer's design needs, the steam plating and slitting shall be carried out.

Storage of Metallised Polypropylene Film

Storage of Metallised Polypropylene Film

  • Prior to use, the metallic film should be kept in its original packaging at a temperature between 5 and 35 °C and a relative humidity of no more than 85%.

  • When exposed to moisture, metalized layers are readily oxidized.

  • As a result, once opened, the film should be utilized as soon as feasible.

  • After opening, a temperature between 15 and 25 °C with a relative humidity of under 60 % is advised.

  • The storage time can be as follows when the original sealed container is kept as described above:

Aluminized film: 12 months after the date of delivery.

Metalized Al/Zn alloy film:

The storage time (as measured from the delivery date) depends on the film's resistivity because zinc is rather unstable:

≦10Ω: 6 months

10-30Ω: 3 months 

>30Ω: 1 month
