Ideal for shopping, these 'intelligent' double-wall freezer bags maintain the temperature of chilled or frozen groceries for up to 6 hours. They use Freeze-LokT technology to insulate contents at below 5?C, and can be used on their own or as linings for your existing shopping bags. They're also great for picnics to keep dishes 'fridge-fresh', or to preserve food while you defrost your freezer.
