Film capacitors use a plastic film as the dielectric (insulator) between the (conductive) plates of a capacitor. Plastics used are; polytetrafluorethylene, polystyrene, polypropylene, polycarbonate, and polyteraphylate (polyester).
Silvered mica uses naturally occurring cleaved sheets of mica as the dielectric. Because mica is a natural material, it is variable quality. In general, silvered mica is not quite as good as polystyrene.
Those Mallorys are probably electrolytic. Some audio uses require electrolytics.

My apologies. You will have to admit, though, that "polyethyleneterphthalate" doesn't roll easily off the tongue (or keyboard). I've just checked in my 1986 Mullard quick reference guide, and it splits them into two words, "polyethylene terephthalate". Which is still a tongue twister.
