Vacuum compression bags can be divided into three categories according to the exhaust mode:


The first type: the exhaust type, which is exhausted through an external exhaust device such as an exhaust pump or a vacuum cleaner.


The second type: rolling type, this type of compression bag is generally small, and the gas is discharged by rolling the compression bag by hand.
