If you want to vacuum pack particularly moist foods, there are several options. For example, if you want to vacuum pack berries to freeze them, it is advisable to freeze them briefly beforehand and then vacuum pack them. This prevents them from being crushed. If you are vacuum-sealing meat, it can help to place a small, film-wide piece of kitchen paper between the meat and the bag entrance before vacuum-sealing. This absorbs the excess meat juices before they enter the appliance.
