Wraps for lunchbox - help!

[Bingtata]

DD is taking her first packed lunch to school tomorrow and she has asked if she can have a wrap, which we often do at home. I've never put one in a packed lunch though, how do I make sure that it doesn't open out in the lunchbox?

I always do ds two of them - make sure you fold in tight, and put them in a box with the join side on the bottom. I squash two of them into a takeaway container and have had no complaints yet! When I tried wrapping them in foil they unrolled as he unwrapped them apparently.

Oh and I always spread the ntire thing with a thin layer of butter or mayonnaise first, because it helps to stick it together.

Thanks cockadoodledoo, I will try that
