Due to the roll paper sheeting machine could be applicated in many fields. We met different kinds of inquiries every day.
Recently, a Turkey friend he wants to find a rotary blade sheeting machine. But it is not the standard configuration we thought.
After deep communication, we know he needs a crack-back slitting unit before the rotary sheeting division. He needs cross-cut the adhesive paper. And our mechanical shear blade could work on it. But here is the remarkable thing: the base silicone layer is cut off, but the adhesive layer stays in one piece so that people can peel the base paper freely after cutting it into big sheets in pallets.
Here let me share the two types of crack-back slitting ways currently used in the market.
One of the most common uses is a rotary die to do creasing cuts on the paper. Another common way is using blades inline with the sheeting machinery to slit the label’s back liner.
Type 2 is the primary type our factory can do. It adopts a pneumatic drive crush blade to slit the base paper, and the air drive power and blade cut angle are adjustable.
The most critical element of a back slit label is getting the proper depth so that you cut the paper but not the adhesive or label material.

If you also work in the adhesive paper industry, how to add this function to your machine? Maybe there will be a type 3 crack-back slitting solution. Welcome to discuss.
