The last thing you need to confirm with film supplier is the rolls diameter.
If the rolls length is too long, maybe cannot be inserted to our air cushion machines.
The distance between material bar and the material pole is about 7cm and the distance between the material bar and the load-bearing feet is about 12cm.
For your reference, our air pillows bags with 20cm width, 500m/roll, 20micron are 5.5cm for the outer diameter. And it works well with our machine.
