To use a shrink wrap bag, place the items in the bag and eliminate excess air by pulling the bag tightly over the items. Use a heating element such as a hair dryer to reduce air within the bag. Firmly tie or attach a twist tie to the top.
Individuals can also use a shrink wrap bag with a food-safe sealer to store food safely in the freezer. Shrink wrap bags are commonly used to decorate baskets or gifts. Eliminating the excess air in the bag puts the items on display and allows people to view the items inside the bag easily.
