I mean the standard lunch box food police is bad enough. Not allowed xyz in pack up.
But for the next two weeks we have to have no packaging waste in the lunch box either. So nothing in individual wrappers, sandwich bags, etc. Ater the two weeks experiment is up apparently it's fine to using as many cheap plastic bags, bits of cling film as you can cram in the box. 
Do the school really thing I'm going to bung sandwiches, cucumber, pepper strips, satay and illegal cake in one Tupperware box with no method of wrapping them?
Dd came home today with no empty sandwich bags which is unusual. Apparently the kids with rubbish at the end of lunch have to put their rubbish in a big bag so at the end of the trial they can see how much they're damaging the world.
