26. How Does MTED Kraft Paper Bag Making Machine Save Your Material Consumption?

You put the number of paper bags you need, their dimensions, and design on a control panel before the production starts.

The paper web width of the kraft paper roll you feed into the machine is according to the paper bag size. Thus the chances to waste the kraft paper are minimal.

Error Detector

MTED’s fully automatic kraft paper bag making machines are well-known for their stable performance. If any error occurs, the kraft paper bag making machine stops by itself.

It saves you from damaging the machine as well as wastage of material.

Kraft Paper Consumption

We design the machine precisely to make paper bags back to back. According to the preset tube cutting length, the roll feeding machines consume the whole paper web by forming paper tubes and cutting the bags.
