This is a better preservative bag.
Traditional preservative bags are not easy to open, especially when the hands are dry.
This kind of preservative bag has a line of removable adhesive coating, whose weak adhesiveness increases the friction between the hands and the bag and helps open the bag easily.
The adhesive coating can seal the preservative bag more simply, instead of with a clamp.
In addition, the coating plays a fixed role, which enables people to take one bag at a time.
