This prevents excessive oxygen concentration from causing anaerobic respiration, thereby avoiding the accumulation of large amounts of volatile substances such as ethanol and acetaldehyde, which would affect the flavor of the fruit. The oxygen concentration inside the film bag can generally be maintained at around 10-15%, and it is highly tolerant of carbon dioxide concentration, making it especially suitable for fruits and vegetables with high humidity, particularly tropical fruits. In other countries, these packaging bags are used to store "frozen" cherries, which can be preserved for 80 days in ordinary cold storage while maintaining the flavor and quality of the fruit.
