What are Potato chip bags filled with?
You may notice that when you open a new bag of potato chips, half of the bag is filled with “air”. That air is actually nitrogen gas. Nitrogen is an inert gas, and is used during the packaging process to exclude and remove air and in particular, oxygen.
What gas is inside chip bags?
Nitrogen is used in chips packets as they fill the space not letting other gases to present inside the packet. Nitrogen is a inert gas which won’t react with the chips and not affects the nature of the packed product.
Why is there so much air in potato chip bags?
As it turns out, the “air” in snack bags isn’t just air at all. It’s taste-preserving nitrogen that fights off staleness and protects bags from pre-snack time squashing.
Is there oxygen in chip bags?
Actually, the answer is no. What many of us have mistaken for atmospheric air in our chip is actually nitrogen. In fact, oxygen would cause the chips to go stale and oils to become rancid. This process is known as “slack fill”, which is even thought to make chips taste better.
Why are potato chip bags half empty?
The Reason You’re Looking at a Bag Half-Full In the manufacturing industry, “slack fill” is empty space that’s intentionally placed around a product. The idea is that the extra room can as a buffer to protect your Lays, Ruffles or Tostitos from damage.
What kind of material is a potato chip bag made of?
A typical potato chip bag is made up of multiple layers of polymer materials: Biaxially Oriented Polypropylene (BOPP) on the inside, low-density polyethylene (LDPE) in the middle, another middle layer of BOPP, and an outer layer of Surlyn®, a thermoplastic resin.
Why are potato chip bags filled with air?
It keeps the chips whole. Finally, bags of chips have nitrogen in them to act as a barrier as the chips are being transported from the manufacturing facility to the store and from the store to your home. The nitrogen acts like a pillow, buffering out any impact so it keeps the chips intact.
Are there any potato chip bags that are recyclable?
Despite being recyclable in a way, potato chip bags need a more tedious process to be recycled. Potato chip bags cannot go into your single stream recycle bin, since most chip bags are made from aluminum laminated with polypropylene.
Why do potato chips have nitrogen in them?
These are the main reasons why bags of chips have nitrogen in them: It gives the chips a longer shelf life. Bacteria need oxygen to thrive, and if all of the oxygen is removed, it can’t grow. This means there is no chance of mold, mildew, or other substances showing up on the chips. It keeps away moisture.

Why are my potato chip bags soggy?
That’s not just any ordinary air puffing up potato chip bags, either: It’s nitrogen. Oxygen can cause the potatoes to spoil and the oil to go rancid, and the humidity found in ambient air makes the chips go soggy. Instead, packages are filled with nitrogen gas to help the snacks stay fresh,…

Why are potato chip bags filled with nitrogen gas?
Even though it may seem like the nitrogen in a potato chip bag is only there to deceive you, it actually serves a very important purpose: to protect the chips from being crushed or going bad. It is especially effective because it does not impact the taste or texture at all.
