Is It Safe to Store Food in Aluminum Foil?
As concerns about food safety and packaging materials grow, many wonder: is aluminium foil a safe choice for storing meals? Scientific evidence and practical use show that foil is generally safe when used properly, but understanding its limitations is key.
Chemical Safety: Minimal Leaching Risks
Aluminium foil is non-toxic and does not contain harmful chemicals like BPA or phthalates. While trace amounts of aluminium may leach into food, especially when in contact with acidic ingredients (like tomatoes or citrus) or high heat, the levels are far below safety limits set by health authorities. For example, a 2020 study found that leaching from foil into acidic foods was less than 0.1mg per serving—negligible compared to the average daily aluminium intake from food naturally.
Potential Concerns & How to Mitigate Them
Acidic Foods: Limit prolonged contact with highly acidic dishes (e.g., marinades) to reduce aluminium leaching. Our LIKEE foil features a food-grade protective coating that minimizes this risk.
Scratched Foil: Damaged foil may leach more aluminium. Always use smooth, intact sheets—our automated production lines ensure uniform thickness and zero defects.
