Fresh & Save Vacuum Bags. All-rounders in size M. There are storage bags, there are freezer bags, and then there are the Fresh & Save vacuum bags. These reusable food storage bags with a practical zip closure are your ace in the hole: whether for freezing, sous-vide cooking, or marinating. With a capacity of 4 liters, you can store a bit more: bread, vegetables, meat, or fish – it's that easy to turn your fridge and freezer into your personal freshness counter at home. Simply fill the bag with the food or prepared meal and seal it. Then, just place the powerful vacuum pump on the valve; it removes the air from the bags at the push of a button in seconds and stops automatically when the process is complete. After that, just press the push button in the center of the red silicone valve briefly to securely seal it: flavors and vitamins are reliably preserved, and food stays fresh up to five times longer! Freezer burn doesn't stand a chance! By the way, meat or fish can be vacuum-marinated in no time. The included marinating attachment makes it a breeze. To ensure your food isn't forgotten in the fridge or freezer, you can easily log it in the ZWILLING Culinary World App: scan the printed QR code before filling the bags and then track your supplies. Thanks to the app's automatic reminder function, you'll receive timely notifications when it's time to defrost and consume the food. Conveniently, each vacuum bag has an individual bag ID, so similarly looking supplies can never be confused again.
