While aluminum is commonly used in food packaging materials, the risk of allergic reactions to aluminum is generally low for most people. Aluminum is not a known allergen, and exposure through packaging is typically minimal. However, individuals with a rare condition called contact dermatitis may experience skin irritation from aluminum. For the general population, the risk of allergic reactions due to aluminum in food packaging is negligible. It's always important to monitor any unusual reactions and consult a healthcare professional if concerned.
