When you wrap something with newspaper and put it in the freezer, several things can happen:
Insulation: Newspaper can provide a certain level of insulation. It can help maintain the temperature of the item you are wrapping by reducing the rate of heat transfer. This can be beneficial for keeping the wrapped item colder for longer.
Moisture absorption: Newspaper has absorbent properties and can absorb moisture from the surrounding environment. This can help in preventing excess moisture from reaching the wrapped item and potentially affecting its quality or texture.
Odor absorption: Newspaper has the ability to absorb odors. This can be useful if you are wrapping an item with a strong odor, as the newspaper can help contain and minimize the smell from spreading to other items in the freezer.
Protection: Wrapping an item with newspaper provides a layer of protection against potential freezer burn or damage. It can create a barrier between the item and the freezer environment, reducing the chances of ice crystals forming on the surface of the wrapped item.
However, it's worth noting that newspaper alone may not provide the same level of protection as purpose-made freezer bags or containers. These specialized materials are designed to provide superior insulation and protection against moisture and air. If you require long-term storage or want to ensure the best possible preservation of your item, it's recommended to use proper freezer-safe packaging.
