Many meat purchases are less expensive if purchased in quantity, but frost-burn used to work against it. FoodSaver provides the ability to divide and freeze one-meal packages in a frost-free, sanitary way. You can make meatloaf/meatball mix in quantity and save it in single-meal portions for freezing instead of making a batch for single-use that ends up having half of it thrown away. Clean the sealer area with a Clorox wipe and feel confident you've not contaminated the meat.
