I have read for like steak and salmon etc . which you aren ' t doing for very long freezer ziplocs are fine . However if you were doing say a shortrib or something where you are sousvideing for like 2436 hours they say you should use a system like FoodSaver bags . <| sep |> I added text to this post but it didn ' t save .
