What Does It Mean When Food Packaging Expands?
When food packaging expands, it usually means that there has been a buildup of gas inside the package. This can occur due to fermentation or the release of gases from the food itself, or from microorganisms present in the food. In some cases, it may also be a sign of bacterial contamination. Expanding food packaging can indicate that the food is no longer safe to eat, and should be discarded.
