1. Before and after inflating the vacuum bag, be careful not to let it be scratched by sharp objects. It is best to operate it on a bed or on a clean table. If there are sharp hard objects in the stored items, be extra careful. Place in vacuum bag. Also, pay attention to the storage location to see if there are any sharp objects to ensure the integrity of the bag. This is the most basic.
2. The items you put in should be far away from the mouth of the bag. If they are close to the mouth of the bag, they may easily expand. This is a common situation. It is recommended that you buy bags of sufficient size. After all, vacuum packaging bags are relatively cheap. A larger size bag won't cost much more.
3. Clean the items to be stored to prevent foreign matter from causing damage to the bag. This is also easy to understand. Foreign matter will cause the seal to be loose. A customer encountered this problem a month ago. The sealed food was not cleaned in advance, causing all the sealed food to deteriorate. The abnormality was not discovered until the smell emitted. The loss was heavy. We should take this as a warning.
