Organic shouldn't be in plastic
But according to the initial questioner, Swiss law concerning organic packaging prohibits packaging made out of "PVC or other chlorinated plastics." I wonder if that plastic packaging is biodegradable, or are we on to something?
Plastic wraps are simply not ecological. In the USA I've seen organic fruits and vegetables with stickers or cardboard/paper bands. Some will argue that there are chemicals in the glue that hold the stickers to the produce. And they are a pain to take off and deal with once they are in the compost, but somehow I think these are a better choice.
Also noted: the cheaper non-organic tea bags at Migros are sold loose in one cardboard box, unlike the organic variety which are individually wrapped.
