Pick up and reuse sturdy plastic packaging

Perhaps a bit cheap the tip, but I have not seen him here: I'll wash large sundae packaging from the TK chest or other plastic packaging with a closing lid in the dishwasher and use it several times for leftovers, cheese, sausage, etc.

Why buy expensive Tupper or emsa plastic? Who has to save, can come with such packaging easily and free of charge to a few cans in various practical sizes, provided he had bought the products anyway.
