Great idea but not thought out completely. It’s great for just meat or dry foods. The minute you try to marinate or add any liquid to the pack along with meatfish the vacuum pump sucks up the liquid through the hole in the plastic, allowing the liquids to go into your machine. I don’t think that’s good for the vacuum pump as there’s no way to get it out. Not only is it bad for the parts but it’s also unsanitary.
