Differences between inner earloop and outer earloop lie in their appearance as well as production process. We can explain it in a simple way.
If we compare the inner earloop and outer earloop non-woven mask, we will find that there is an added piece of non-woven on the edge of mask.
The below pictures are outer earloop mask.
The below pictures are inner earloop mask.
The below picture is inner earloop mask vs outer earloop mask.
The below is the picture of our outer earloop mask welding machine.
The below is our inner earloop mask welding machine.
Among our earloop mask welding machine, there is an additional non-woven roll on inner earloop welding machine.
