What is the difference between WEET Metal foil capacitor (Pure aluminum foil and film Capacitor) and WEET Metallized Polypropylene Film Capacitors?

Metal foil capacitor is also a film capacitor. What you understand is that the electrode plate is aluminum foil and the medium is film;
A metal film capacitor is a capacitor made of a metal film (such as aluminum foil) sandwiched between two insulating films.

Plastic film capacitor can be divided into metallized film capacitor and full film capacitor (full film capacitor means that the electrode is aluminum foil and the medium is Polypropylene Film)
1. The metallized film capacitor has the ability of self-healing, but the high-frequency characteristics and current carrying capacity are poor;
2. The foil capacitor has no self-healing ability, but it has strong high frequency characteristics and current carrying capacity, which is special designed for audio systems
