When the oxygenand moisture in the package create a suitable environment, microorganisms will growand release carbon dioxide gas, which will cause mold and mildew in the food, andbag swelling. Packaging of substandard quality will cause the above issues:
1) Poor barrier properties – when the packaging materials is of poor oxygen and water barrier properties, it causes oxygen and water vapor to slowly penetrate into the packaging during long-term storage of food.
2) Poor sealing performance – for instance, poor sealing performance of the package caused by incorrect heat sealing parameters, outside air and moisture will enter the package from the heat sealing site.
3) Inferior physical and mechanical properties - such as packaging materials are weak to punctures; or pinholes, creases, and damages on the packaging materials due to the kneading or squeezing during production and storage. If the damages were not discovered in time, the food would be exposed to a large amount of oxygen and water vapor which may lead to mold and mildew.
