Chip Bag Explosions: Airport Security's Worst Nightmare

Many travellers wonder if it's safe to bring snacks like bags of chips on a plane, and whether the change in air pressure during the flight could cause them to explode. While air pressure does impact sealed bags, it is unlikely for a bag of chips to explode during a flight. The pressure in an airplane cabin is typically maintained at an equivalent altitude of 6,000 to 8,000 feet, which may cause the bag to expand but not burst.

Why chip bags don't explode in an airport

Many travellers wonder if it is safe to bring snacks like bags of chips on a plane, especially considering the air pressure changes during the flight. The main concern is whether the bag will explode due to these changes, which could create a mess or cause panic among passengers.

It is important to note that while air pressure does impact sealed bags, it is unlikely for a bag of chips to explode during a flight. The pressure in an airplane cabin is typically maintained at an equivalent altitude of 6,000 to 8,000 feet, which may cause the bag to expand but not burst. This means that the air pressure inside the plane is lower than at ground level.

As the aircraft climbs, the atmospheric pressure decreases, causing the bag of chips to expand. The bag may puff up due to pressure differences, but it is more likely to simply expand rather than explode. In most cases, an explosion would only occur if a significant amount of extra pressure is applied to the bag, such as when handling or grabbing it with force.

Chip bags are designed to withstand pressure changes during transportation. Any competent US maker of chips will design their product to be shipped via road or rail, which often involves traversing high-altitude routes. If the packaging was not able to handle these pressure changes, manufacturers would face the issue of entire container loads of chips being ruined before they reach stores.

Additionally, some types of chip packaging can better withstand changes in cabin pressure. For example, brands like Pringles are packaged in rigid containers that minimize the risk of expansion or explosion.

Why chip bags might explode on a plane

Many travellers wonder whether it's safe to bring snacks like bags of chips on a plane, especially considering the air pressure changes that occur during the flight. The main concern is whether a bag of chips would explode due to these changes, which could potentially create a mess or cause panic among passengers.

While it is unlikely for a bag of chips to explode during a flight, air pressure changes in a plane can cause chip bags to expand. The pressure in an airplane cabin is typically maintained at an equivalent altitude of 6,000 to 8,000 feet, which may cause the bag to expand but not burst. As the aircraft climbs, the atmospheric pressure decreases, causing the bag of chips to expand. The bag may puff up due to differences in pressure, but it is more likely to simply expand rather than explode.

The force on the bag depends on the pressure difference between the outside and inside. If the pressure inside the bag is different from the pressure outside, there is an overall force that stresses the bag. As the plane climbs in altitude, the cabin pressure drops, and the bag will inflate further as the gas within tries to expand. If the seals are faulty, the bag may pop.

In most cases, an explosion would only occur if a significant amount of extra pressure is applied to the bag, such as when handling or grabbing it with force. The likelihood of a chip bag popping open is quite small, and it is more common for the bags to simply expand without bursting.

How to prevent chip bags from exploding

Chip bags can expand and sometimes even burst open due to changes in air pressure when flying. This is more likely to occur in the cargo hold of a plane, which is not always pressurized, than in the passenger cabin, which is typically maintained at an equivalent altitude pressure of 6,000 to 8,000 feet.

To prevent chip bags from exploding, there are several measures you can take:

• Use rigid containers: Storing chips in rigid containers, such as Pringles tubes, can help withstand changes in cabin pressure better than flexible bags, reducing the risk of expansion or explosion.
• Resealable food pouches: Using resealable food pouches instead of the original chip bags can provide a more durable and convenient option while maintaining freshness and flavor.
• Poke a small hole: If you are sending chips by air to friends or family, you can try poking a small hole in the chip bag to allow air to escape, preventing a pressure buildup that could lead to an explosion.
• Alternative shipping methods: Consider shipping methods that do not involve airplanes, such as ground transportation or shipping via boat, to avoid the rapid air pressure changes that occur during air travel.
• Carry-on baggage: If you want to bring chips on a plane, consider packing them in your carry-on baggage, where the cabin pressure is more stable and less likely to cause the chip bags to explode.

The science behind chip bags and air pressure

Chip bags are packed and sealed in airtight containers on the ground, where the air pressure inside the bag is the same as the pressure outside. However, as an aircraft climbs, the atmospheric pressure decreases, leading to a pressure difference between the inside and outside of the chip bag. This pressure difference causes the bag to inflate as the gas within tries to expand, and in some cases, it may even burst.

The cabin of a commercial aircraft is typically pressurised to an equivalent altitude of 6,000 to 8,000 feet, resulting in a lower air pressure inside the plane compared to ground level. This pressure change can cause chip bags to expand but not necessarily explode. The bags may puff up due to the pressure difference, but they are more likely to simply expand rather than burst.

The force exerted on the chip bag depends on the pressure difference between the outside and inside of the bag. This force per unit area is defined as pressure, measured in pounds per square inch (psi). As the plane climbs in altitude, the cabin pressure drops, increasing the pressure difference and causing the bag to inflate further. If the seals on the bag are faulty or the bag is weakened or over-pressurised, it may fail and pop.

The likelihood of a chip bag exploding during a flight is relatively small. In most cases, an explosion would only occur if additional pressure is applied to the bag, such as when handling it with force. The packaging of some chip brands, such as Pringles, is designed to handle changes in cabin pressure better than typical flexible bags, reducing the risk of expansion or explosion.

To prevent chip bags from exploding during air transport, it is recommended to poke a small hole in the bag to allow air to escape or choose alternative shipping methods that do not involve airplanes.

Chip bag explosions: rare occurrence or common issue?

It's a scenario that many travellers have worried about at some point: you're on a plane, and suddenly, the bag of crisps in your hand explodes, leaving a mess and potentially causing panic among passengers. But how likely is this event to occur?

Firstly, it's important to understand the science behind chip bag explosions. The cabin pressure in an aircraft is typically maintained at an equivalent altitude of 6,000 to 8,000 feet, resulting in lower air pressure inside the plane compared to ground level. As the plane climbs, the atmospheric pressure decreases, and any sealed bags of crisps will expand due to the difference in pressure between the inside and outside of the bag.

While it is true that changes in air pressure can cause chip bags to expand, the likelihood of them actually exploding is quite small. The bags are usually sturdy enough to handle the drop in air pressure as the plane reaches cruising altitude. In most cases, an explosion would only occur if extra pressure is applied to the bag, such as grabbing it with force.

However, there have been reports of chip bags exploding during flights. Some factors that could contribute to this include faulty seals on the bags or weakened packaging. Additionally, in unpressurised or not-fully-pressurised areas of the plane, such as the cargo hold, the pressure difference may be greater, increasing the risk of the bags popping open.

To minimise the risk of chip bag explosions during air travel, passengers can consider alternative packaging options, such as food pouches or rigid containers. These options provide a more secure way to store crisps and reduce the chances of mess or disruption caused by explosions.

In conclusion, while chip bag explosions on planes are not a common occurrence, they can happen under certain circumstances. By understanding the science behind these explosions and taking simple precautions, travellers can minimise the risk and enjoy their snacks without worry.
