Bubble film machine (air cushion film machine) and air column machine

1, the principle is different

The bubble film machine (air cushion film machine) is damped by the volume compression of the gas.
The gas column is damped by physical structure

2, the difference in focus

The focus of the bubble film machine (air cushion film machine) is buffering, only one process
The introduction of the gas column is to absorb energy and then release energy, which is equivalent to two processes.

Advantages and disadvantages
1, the bubble film machine (air cushion film machine) has a single process, small elasticity, small footprint, good shock absorption effect
2, the gas column will have a secondary bounce process, occupying a large space, may cause secondary vibration, shock absorption effect is very good

Different use range
1, bubble film machine (air cushion film machine) is suitable for the packaging of small objects,
2, the air column machine is suitable for the packaging of large objects
