• Good resistance - It is very effective in blocking air, moisture and light, which helps in keeping the food fresh.
• Good conductor of heat- It is a good conductor of heat, allowing food to heat quickly and evenly.
• Reuse – Aluminium foil can be reused.

Disadvantages of Aluminum Foil

• Aluminium Leaching – Aluminium foil may leach aluminium when it reacts with certain food items, which may be harmful to health.
• Reaction with acidic food items – Aluminum can react with acidic food items such as tomatoes, lemon, and vinegar, which may change the taste of the food and increase the amount of aluminum in the food.
• Reaction at High Temperatures: Cooking in aluminium foil at high temperatures can also cause aluminium to leach out.
