It employs flush cut as the type of cutting, allowing customers to make pasted valve sacks with either graduated or straight-out cut ends.
Moreover, our valve bag tuber can be paired with valve sack bottomer to make kraft paper bags of 500-1100mm in length, 350-620mm in width and up to 80mm of bottom width.
