Is Aluminium Foil Paper Safe for Wrapping Food?
September 17,2025
“Is aluminium safe?”
“Is it alright to wrap food in aluminium foil?”
“Doesn’t the metal leach into the food?”
“Are we unknowingly consuming metal?”
The list of concerns about aluminium foil seems endless. Yet, most of us have used aluminium foil at least once in our lives. And what a saviour this lightweight, shiny roll of durability has been!
From keeping your parathas and rotis warm to sealing in the aroma of that perfectly grilled fish, aluminium foil has been an unsung hero in kitchens, picnics, tiffins and takeaways. But there is a quiet panic and concern about the safety and health risks that deserve to be addressed once and for all.
And Hindalco Freshwrapp is here to debunk any myths and address your concerns.
Why is aluminium foil so popular in the first place?
Aluminium foil is an indispensable kitchen tool, and a 72-metre aluminium foil like Freshwrapp is incredibly versatile because it:
- Keeps food fresh for longer
- Protects it from light, moisture and bacteria with its FreshLock Shield
- Keeps flavours intact and aromas sealed
- Prevents food from drying out
- Prevents fridge odours from entering any covered up food trays or containers
- Retains the freshness and taste of the food when packed for tiffins and snacks
This means your food – fresh or leftovers – tastes just as fresh as when you packed it. No bacteria. Just you and your favourite food!
Also, not only is aluminium recyclable, aluminium foil helps cut down food wastage, a global problem that’s not just about hunger, but also about resources, energy consumption and has a huge environmental impact.
Here’s the honest truth:
1) Aluminium leaches into food:
In all honesty, there is a possibility. Aluminium can migrate into food, but only under certain conditions. Studies show that acidic or salty foods (think tomato curry or lemon fish) wrapped in foil and cooked or stored for long periods can cause more aluminium to transfer into the food.
However, the amount of aluminium that may transfer to food when using foil is well within the safe range set by the World Health Organization (WHO). In fact, WHO states that an adult can safely consume up to 2 milligrams of aluminium per kilogram of body weight per week. This is much more than what you’d ever get from occasionally wrapping food in foil.
In other words, your roll of aluminium foil is completely safe when used correctly. The key lies in how and when you use it:
For hot, acidic, or salty food:
Store in glass or food-grade containers instead of foil.
For room temperature or dry food:
Freshwrapp aluminium foil is the perfect ingredient for wrapping rotis, sandwiches, baked goods and more.
For cooking or baking:
Use Freshwrapp aluminium foil to cover or line trays to avoid prolonged contact with acidic marinades.
2) Aluminium foil is toxic and should never touch food:
Aluminium is everywhere and all around. Which means it’s already present in many things we eat and drink. In fact, most of the aluminium in our bodies comes from untreated food sources (over 60%) and food additives (up to 40%). Only around 4% comes from contact with uncoated aluminium items like cooking trays, utensils, or foil.
Thus, we can safely assume aluminium foil is safe when used as intended. Premium, food-grade foils like Freshwrapp meet international safety standards and are designed specifically for food contact. So, be rest assured, and wrap your food or store it in Freshwrapp aluminium foil and containers.
Why Freshwrapp aluminium foil is different
Not all foils are created equal. Freshwrapp is made from premium food-grade aluminium, which is specifically manufactured for safe use in cooking and food storage.
