6. 2-5-6 Foil Bags When first opening foil storage bags, make certain to cut only at the heat sealed end. Carefully cut as close to the heat seal line as possible. This will allow the bag to be partially vacuum packed and re-sealed in the future. When first opening foil storage bags, make certain to cut only at the heat sealed end. Carefully cut as close to the heat seal line as possible. This will allow the bag to be partially vacuum packed and re-sealed in the future. - Once the bag is resealed, the 270 day inspection cycle stops.
