Yes, but it depends on the previous contents of the bag. FoodSaver® Bags that previously contained fruits, vegetables, breads and dry goods can be washed and reused. FoodSaver® Bags that contained raw meats, fish, eggs or un-pasteurized cheese should be discarded after use because they may contain invisible bacteria that will remain after washing. FoodSaver® Bags that contained greasy or oily foods should also be discarded, as they may be difficult to clean. FoodSaver® Bags can be washed by hand. Dry completely. They can then be re-vacuumed.
