Why Does Food Packaging Bloat?

When you purchase food or juice pouches, you might notice that a few pouches are bloated. Generally, there is a warning written on pouches that if a packet is bloated, it should not be purchased.

Bloating is a clear indication that bacteria are present inside the packet. Bacteria feed on the contents of the pouch and produce gas. Since this gas cannot escape from the sealed packet, it accumulates inside and causes the pouch to bloat.


Bacteria can sneak into the food packaging in several ways:

  1. During the process of manufacturing — If the packaging machine is contaminated by bacteria, a large number of pouches can get infected.

  2. Through a puncture — The packaging may get punctured due to rough handling or during transportation. Besides exposing the food to bacteria, the puncture also exposes the food to moisture and air. Some retailers simply reseal the foil pouches when they detect a puncture. The bacteria may get inside as soon as the packaging gets punctured, and the resealing will not allow the gas to escape.
    This will cause the bag to bloat.

Food packaged in bloated pouches may contain harmful bacteria, and hence it is not fit for consumption.

We at StandUpPouches.net make sure that this does not happen. Our stand up pouches are puncture resistant and effectively prevent bacteria from entering the packet.

Stand up bags are made of multiple layers of superior quality barrier film that protect the contents of the bag from a range of environmental and physical hazards.
