The plastic between the leaves is most likely for sound deadening as the leaves slide across each other... They will work without them, but may be a little squeaky and creaky....

But like Chris says, they should have known if that's their business... I would see if they will replace them...

What worries me more is the powder coating as a pack. I know when I painted my leaf packs, the paint cracked and flaked off on the sides after a couple trips down the road. Granted that was 15 yr old me and I made even more mistakes back then but still.
