If I put food in party boxes for a 4 year old do I wrap it?

I'm thinking rolls/sandwiches do they need cling film?

How do I contain crisps / grapes / pizza - some sort of bag? if so what sort?

I'd cling film rolls or sandwiches, and put foil round pizza. Grapes I'd just leave loose, I think, as long as they were pretty dry. I'd just give them a whole bag of crisps, so no idea what you'd do if you were splitting a big bag.

sandwich bags for everything
