Apologies for assuming that the original poster was referring to a change from plastic to paper, (there was a similar discussion a few weeks ago complaining of just that). As I said above, I rarely have chocolate like that. Is what you refer to as 'foil', pure aluminium, or metallised (plastic) film - a material that is almost impossible to recycle successfully? Pure aluminium foild is easily recycled provided the user separates it from other waste material.Roses used to contain a selection of foil and paper wrappers as well as plastic ones. Now they've gone completely over to plastic which also uses more space.
It will be interesting to do a similar comparison on Quality Street.
