MPX-X2 Caps

When istalled or replacing MPX metallized polypropylene caps does it matter which way you install them? There's no markings on them to determine positive and negative. They are to be installed for EMI suppression on a power supply board. The schematics don't say either way. Thanks for you time.

If they have a bar marking on one side it signifies the outer foil layer. That should be connected to ground side.
