On tetra pack of fruit juices it is printed IF THE PACKET IS PUFFED DO NOT BUY What the reason?

Tetra Paks are a type of packaging made from layers of paper, plastic, and aluminum. They are commonly used for packaging liquid foods, such as fruit juices, milk, and soups.

The warning "IF THE PACKET IS PUFFED DO NOT BUY" is printed on Tetra Paks because a puffed packet can indicate that the product has been spoiled. This can happen if the Tetra Pak has been damaged, allowing air to enter the package. When air comes into contact with the food, it can cause the food to spoil. Additionally, a puffed Tetra Pak can indicate that the product has been exposed to high temperatures, which can also cause spoilage.

Consuming spoiled food can cause foodborne illnesses, such as vomiting, diarrhea, and abdominal cramps. In some cases, foodborne illnesses can be serious and even life-threatening.

Therefore, it is important to follow the instructions on Tetra Paks and avoid purchasing any packets that are puffed. If you do purchase a Tetra Pak that is puffed, it is important to discard it immediately.
