A swollen food package can immediately raise concerns, but not every inflated package means the same thing. Some are designed that way, while others may signal a problem.
The extra air inside chip bags is usually intentional. Many snack companies fill packages with nitrogen to protect chips from breaking and help maintain freshness during transport.
This space is not a trick to reduce the amount of food. It acts as a cushion, keeping delicate snacks safe before they reach the store.
However, unusual swelling in refrigerated foods like dairy products, cheese, meat, or ready-to-eat meals should be treated differently. It can sometimes indicate changes inside the package.
