From photos you may see the difference between these two strapping seal/clips.
Is the machine same to produce them all?
No not at all
1 Single fold seal/clip machine
It is relatively easy to make the single seal/clip by pressing the two ends down and make the shape by squeezing them from two sides
to wrap together and have a beautiful finishing. as shown at below photos.
2 but for the double fold strapping seal/clip making it needs five small" arms" to push from different angle and form the shape of double folding
as shown in the video below
