Polyester film capacitors are film capacitors using a dielectric made of the thermoplastic polar polymer material polyethylene terephthalate (PET).

Capcitor with polyster film as dielectric film , is called as Polyster capacitor

A metal film capacitor is an electrical part that holds energy electrostatically inside of an electric field. The capacitor has a dielectric which separates two electrical parts which are made out of thin film.

Last time I looked there are no 47nF polarized capacitors. The value is too small to make practically.
*to store charge. *to smooth out(reduce ripple on dc) a voltage
The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.
We don't know much about the circuit these capacitors are in, but they are coupling capacitors. Coupling capacitors isolate DC between stages or circuits, and they couple AC between those circuits or stages. Only the signal gets in and goes out. The DC the stage operates on is isolated from stage to stage.
All capacitors are essentially charge holding components that build up a charge on either side of two plates, and then disperse it later. By nature they are not polar, so, no, they do not have a direction.
The capacitors those are polarity sensitive are called electrolytic and tantalum capacitors. These capacitors are labeled as positive and negative.
Capacitors are rated in Microfarads
because normal capacitors does not have any polaririties.
