The Difference Between Aluminum and Tin Foil

Aluminum Foil

What Is Aluminum Foil?

Aluminum foil is a thin sheet of metal foil or metal leaf composed of an aluminum alloy containing roughly 92–99 percent aluminum. It usually has a thickness between 0.0002 to 0.006 inches, but its width and strength vary greatly based on the intended application. 

Just some of those applications include:

  • Manufacturing thermal insulation
  • Creating fin stock for air conditioners
  • Making capacitors for electronic devices
  • Creating insulation for storage tanks
  • Packaging food
  • Making containers
  • Building electric coils for transformers

The popularity of aluminum foil stems from the fact that it’s a highly versatile product that can be used in limitless ways. It’s a durable, non-toxic, greaseproof material capable of resisting chemical attacks. It also offers decent magnetic shielding and is an excellent electrical conductor. 

The best part? Making the foil itself is a relatively inexpensive process.

Aluminum Foil Industry Usage

The packaging industry captures the vast majority of the aluminum foil market. As the foil is nearly impermeable to gases and water vapor, it’s used in various products – from foodstuffs to gifts! 

Foil can extend the shelf life of products, it takes extremely little storage space, and it produces lower waste than its counterparts. With all these positives, it’s evident why aluminum foil is so popular.

Manufacturing Process

Aluminum foil is made by converting billet aluminum into rolling sheet ingots. This process is replicated in sheet and foil rolling mills to obtain the desired thickness. 

Concerning the debate between the shiny and dull sides: there’s no “right side” of a foil sheet. The texture differences only arise due to the manufacturing process itself, and either side of aluminum foil is safe to use.

With “hobo packs”, the aluminum foil becomes the cookware.

Uses in Cooking and Food

The fact that aluminum foil is entirely recyclable makes it a great asset in the quest for greener living. As long as your aluminum foil isn’t dirty, you can reuse it in the kitchen.

And its usability in the kitchen is legendary. It’s used in packaged products such as cream cheese and candy, you can use it to store leftovers, and you can even use it as a cooking surface.

And why stop at a surface? The Boy Scouts introduced the world to the magic of hobo packs, which involve placing cut-up pieces of various ingredients in foil and roasting them over a fire.


Why should we Recycle Aluminum Foil?

Aluminum is one of the highest-valued recyclable materials around, and the rate at which it can be repurposed is very fast, generally within 60 days. Nearly 75% of aluminum that has been manufactured in the U.S. is still in circulation, and we as Americans dispose of enough aluminum foil yearly to build an aircraft fleet.

Deliciousness With Aluminum Foil

Suppose you’re in hand with a roll of foil and about to cook or prepare food, don’t skip this section. Since I’m positive that it’ll give you some delightful information.


With its waterproof and greaseproof features, along with aluminum foil’s standard thickness, it can efficiently lock the moisture of your foods. This isn’t just a storage method, but cooking foods wrapped with aluminum foil will also maintain their tenderness and juice.

When storing food, it’s not a bad idea to opt for heavy-duty aluminum foil. With the undeniable distinctions between heavy-duty and regular aluminum foil, you’ll see that the heavy-duty one can maintain your food’s freshness much more better.


Talking about keeping the tenderness and juice of food, you can find other substitutes for aluminum foil, such as butcher paper or parchment paper. I’d suggest you compare butcher paper with parchment paper to know for sure which one best suits your preferences.

However, these substitutes meet the problems with open flames – which is absolutely no problem with aluminum foil. With a significant melting temperature at 1220oF, aluminum foil is among the handiest items of the pitmasters.

So if you’re ever feeling like making some lip-smacking desserts with your trusted grill, don’t forget to utilize aluminum foil as your sidekick.

One of the questions that most people will have when using this product is probably “Can I use aluminum foil in ovens?”. Considering aluminum foil’s paper-thin appearance, it’s not hard to imagine that some would worry the product can catch on fire while in the oven.

However, there’s no need to worry about such unlikely things. Thanks to its high heat resistance, aluminum foil is oven-safe. There are multiple methods to cook with aluminum foil in the oven, such as wrapping, covering, or lining.

Can I Recycle Aluminum Foil for Money?

The short answer is no; even though it is made from the same material as soda and beer cans, aluminum foil is used for food storage and transportation. Due to the risk of food contamination, many recyclers will not pay for it.

Even if you could find a company willing to pay for it, aluminum is so lightweight that you would have to recycle massive amounts to make any money from it.


At this point, I’m positive that you’re well understood that tin foil and aluminum foil are different things. However, if you’re still confused with the information or struggling with using aluminum foil, here are some of the most asked questions to solve your problems.

Is parchment paper toxic?

Yes, parchment paper is absolutely safe forcooking. Parchment paper is a sheet of paperimpregnated with silicone, which makes the paper grease- andmoisture-resistant as well as relatively heat-resistant. since thebleached one contains toxic dioxin, it is better to use theunbleached parchment paper.

The Downsides Of Tin Foil

Tin foil is so convenient in the kitchen.

Tin foil is so convenient in the kitchen.

You reach for it when you want to cover a lasagna that’s cooking in the oven, or when you want to wrap some food leftovers or cover your fresh salad (after tossing it with eco-friendly bamboo salad servers, of course!). But aluminum foil comes with many drawbacks.

These include the following:

It Can Be Harmful To Health

Some research has found that tin foil can be harmful to our health by increasing the amount of aluminum in our bodies.

Aluminum containers and cooking utensils, as well as aluminum foil, all leach aluminum into food, as reported by Healthline. While the amount of aluminum we’re exposed to is considered safe, the site goes on to say that research has found higher levels of aluminum in people with Alzheimer’s disease.

It’s Bad For The Environment

Producing a ton of aluminum requires 170 million BTUs (British Thermal Units, a measure of energy).

This is the equivalent of 1,400 gallons of gasoline. It also releases approximately 12 tons of greenhouse gases.

Unlike the regular aluminum, which is often used to contain refillable zero-waste products, aluminum foil is not infinitely recyclable. When it’s disposed of, aluminum takes 400 years to decompose, as Curiosity reports.

Luckily, you don’t have to continue using aluminum tin foil in your home.

There are safer and eco-friendlier options available to you. 

Related Questions

Why Should You Avoid Aluminum Cookware?

Although it’s considered safe, it releases aluminum into food.

Acidic foods, like tomatoes, cause more aluminum release, and longer cooking or storing times also increase the amount of this metal that enters your food, as reported by Livestrong.

How Can You Cover Foods Cooking In The Oven?

There are many options instead of using aluminum foil. Use a metal lid, silicone lid, or baking sheet to cover your foods.

The benefit of these items is that you can reuse them for a long time and for other uses around the kitchen.

Is Parchment Paper Eco-Friendly?

It’s not eco-friendly – it’s made with the use of chemicals like acid, sulfur, and chlorine, which can seep into foods.

In addition, it’s not very sustainable because parchment paper is brittle and coated with silicone to make it non-stick.

This is also what makes it hard to recycle and you can’t compost it.

Can you tell the difference between aluminum and tin foil?

It’s pretty hard to tell them apart, given that tinfoil isn’t widely used anymore. Their appearance is similar enough that most people wouldn’t know unless they were to physically use both to compare. In general, though, tin foil is “less sturdy and stiffer compared to aluminum and can also leave a bitter taste in the food.”


Real tin foil these days is used more for things like electrical capacitors than food prep or storage. It still can be used for packaging materials and such, but since it’s not the popular or cost-effective choice, it’s rare that you’ll find actual tin foil in your local grocery store. More often than not, it’s okay to assume the foil covering your roasted veggies is aluminum.
