1. Natural phenomena: Air bubbles are usually caused by small air bubbles within the bag. This is a natural phenomenon and will disappear naturally after a period of time. Insufficient vacuum level: This is a common and direct cause of air bubbles. Because it's difficult to achieve a complete vacuum by removing air from moisture, and if the vacuum pump is small and the vacuuming time is short, air can easily remain in the packaging, making it difficult to achieve a true vacuum.

2. Related to the vacuum bag and the vacuuming time: If the vacuum bag is thin or the vacuuming time is too short, air bubbles may occur. Therefore, it's important to set the parameters correctly before vacuuming.
