The flexible circuit shouldn't be damaged by bending unless the bends are very sharp. Its a little stiffer than a plastic bag.
Single layer PCBs have only a single layer of copper traces. Multi layer PCBs have several copper layers stacked up and can be connected with vias between the layers. The more layers on a PCB the more complicated the circuit can be. 2 or 4 layers is fairly standard.

I have a very small (narrow) place to mount my PCB and that's why i want it to be a flexible PCB so that i can bend it somehow to make it fit that place.
Now....if i increase the number of layers of the FPCB, can i make my circuit smaller and smaller?
Probably, obviously the limit is the size of the components, I don't know if you can get flexible PCB's as multi-layer?. But all multi-layer does is glue thin PCB's together - so a four layer board is simply two double layer boards glued together (with some kind of insulation in between) and through hole plating joining the layers.
The first Pace Digital satellite receivers (for Australia or South Africa, as I recall) had massive early failures - all at roughly the same time. The four layer boards hadn't been cleaned properly during manufacture, and traces of etchant were left between the two boards. This resulted in tracks been etched away during use, and they all failed within a few weeks of each other :lol:
It might sound pretty cool for small electronics, but for something with bulky capacitors and/or heatsinks your better off sticking with your normal PCB.
can't you laminate a piece of copper foil to a transparency (with heat) and then etch your own board yourself???
