Please allow me to add to that answer, Mr. Lehoux.
Earlier Mr. Lemaire discussed food waste, which is a serious problem.
Plastics help preserve products for much longer periods. We're talking about grocery basket affordability here. Take two pieces of broccoli, one wrapped in plastic and the other without plastic packaging. Put them in your vegetable drawer and see how long they're preserved.
Food waste is also a problem. We mustn't solve one problem by creating another.
