The Transportation Security Administration has particular regulations enabling you to carry solid foods in your hand luggage and other foods in your checked bag. Still, the issues emerge with how they are packaged.
You might have to undergo additional screening if TSA inspectors are worried about the items you use to wrap your food. The TSA permits you to bring items wrapped in aluminum foil in your checked or carry-on luggage.
However, you may have even heard of the TSA operative who made other TSA officers remove rolls of aluminum foil from suitcases. While it wasn’t the aluminum foil that was at fault, the jagged edge on the box could have been used as a weapon.
In our guide, you can learn more about the current flying rules with aluminum foil in your carry-on and checked baggage. By the end, you’ll better understand how to use aluminum and if the TSA X-ray machines detect if you have something hiding in foil. (Read Can I Take Tamales On A Plane)
Does Tin Foil Set Off Metal Detectors?
The Transportation Security Administration is the team that checks your carry-on bags at the airport security checkpoint. As part of their responsibility to protect travelers, they scrutinize checked luggage behind the scenes.
They don’t mention aluminum foil on their website, so aluminum foil rolls, or tin foil as it is also known, can be packed in both hand luggage as your carry-on bags and your checked bags.
You might also be curious, do foil wrappers trigger TSA x-ray machines or not? Unfortunately, many think aluminum foil will be invisible to the x-ray machine at the security checkpoint.
Since aluminum is not a thick metal, plenty of photons can pass through an aluminum foil wrapper as it goes through the screening process and the x-ray machine.
Remember, airport x-ray machines can see inside aluminum suitcases, so sandwich wraps stand little chance. So you can wrap your pre-prepared food in foil or bring your fast food through the TSA security checkpoint. Just keep in mind that carry-on baggage can only contain solid food.
When passing through the metal detector, ensure you don’t have any aluminum foil wrappers in your pockets, or it could set off the alarm, forcing you to submit to a pat-down additional screening inspection. Since there are many conflicting claims on whether x-rays may penetrate aluminum, it is essential to identify the specific problem.
Although X-rays can pass through aluminum foil, the metal can impede or even bend the radiation. It follows that x-rays can only create visible images if the radiation dose is adequate, and in airport x-ray equipment, the radiation dose is unquestionably adequate.
Should I Pack Food In Aluminum Foil To Fly?
Is aluminum foil the ideal way to package food to keep in your carry-on bags? Aluminum foil isn’t the first option for wrapping your snacks. When passing through security x-ray, it can show as a dark blob, and TSA officers may ask you to unwrap your food item.
It’s inconvenient, time-consuming, and foil will tear, and you won’t wrap your food as well as you did initially. The best method to package food such as sandwiches or dry fruits for traveling is using clear plastic zip-top bags.
Clear plastic containers are best for moist foods and are cheap and leak-proof to carry most foods. Remember, the TSA won’t allow liquids or gels exceeding 3.4 oz (100mL) in carry-ons, including food.
Can You Carry Aluminum Canned Beer?
Although some restrictions exist, you may bring canned beer on your flight. Beer cans are composed of aluminum, but according to the rules on liquids and gels, you cannot bring your new favorite six-pack through security.
The TSA generally allows you to pack bottles (and cans) of alcohol in your checked luggage, but there are special restrictions. Passengers may pack up to 1.3 gallons (5L) of alcohol with an alcohol-by-volume range of 24% to 70%. (48 and 140 proof).
Cans and bottles must both be sealed in retail packaging and unopened. Beer has far less alcohol than 24% ABV; therefore, the only concern you should have is protecting your cans from damage during transportation.
If you choose to purchase your alcohol at the duty-free area of the airport, keep in mind that you cannot consume it while flying, and it needs to stay in your carry-on bags. (Read Can You Bring Nail Glue On A Plane)
Aluminum Foil In Checked Baggage
