Can aluminum be used in food packaging?

Yes, aluminum is commonly used in food packaging due to its lightweight, durability, and excellent barrier properties against light, oxygen, and moisture. It is often used in the form of aluminum foil and aluminum-coated films or laminates to protect food and extend its shelf life. However, there are concerns about the potential health risks of aluminum exposure, and it's important to note that regulations and guidelines exist to ensure that aluminum levels in food packaging are safe for consumers.
