MPP Film
BOPP metallized film is the heart of film capacitors, and FSPG’s powerful production and R&D team can delivers industry-leading film solutions for you.
Metallized Polypropylene Film Capacitor
The core application of MPP Film is “the manufacture of film capacitors,” these capacitors now run through nearly the entire new-energy and power-electronics landscape. The global capacitor-film market is projected to grow at a CAGR of 5.40 % from 2025 to 2030, driven especially by electric vehicles, renewable-energy infrastructure and industrial automation. In these sectors polypropylene-based films are being engineered for higher thermal stability, higher dielectric strength and superior self-healing to meet the rising demands of high-voltage, high-frequency applications. With more than 400 technical staff, over 300 patents and 100+ invention patents, FSPG is ready to deliver high-quality film-capacitor solutions for you.

Advantages of FSPG Metallized Polypropylene Film
Ultra-thin
2.4–4 µm metallized film directly replaces 6 µm grades, cutting DC-link capacitor height by 3–5 mm and freeing valuable volume for 800 V SiC traction inverters, increasing power density by 15%.
High temperature resistance
high-temperature/humidity process withstands 85 °C/85 %RH for 1,000 h with capacitance drift ≤1%; optional low sheet-resistance or safety pattern raises ripple-current capability by 25% and provides short-circuit self-healing, meeting AEC-Q200 without extra moisture-proof housing.
Type Of Metallized Polypropylene Film
Zinc-Aluminum Metallized Film
Zn-Al alloy layer allows Zn to vaporize first during breakdown, absorbing energy and producing cleaner self-healing; capacitance loss <0.5 %, longer lifetime. Key parameters • Metal layer: Zn 70 % + Al 30 % alloy, 30–60 nm • Sheet resistance: 3–6 Ω/□ (customizable) • Typical thickness: 2.5–6 μm
Zinc-Edge-Thickened Metallized Film
1–2 μm Zn overcoat on edge dissolves into sprayed metal during end-spraying, giving excellent adhesion, lower ESR and almost zero side “dead zone”. Key parameters • Metal layer: Al base, edge 1–2 μm Zn • Sheet resistance: 2–4 Ω/□ base, <0.5 Ω/□ on edge • Typical thickness: 3–6 μm
Aluminum Metallized Film
pure Al layer offers the lowest sheet resistance (2–4 Ω/□) and lowest cost; Al₂O₃ passivation provides outstanding oxidation resistance, ideal for high-volume, cost-sensitive applications. Key parameters • Metal layer: 99.9 % Al, 20–40 nm • Sheet resistance: 2–4 Ω/□ • Typical thickness: 2–6 μm
