Vertex™ Divosheet is a highly flexible polyethylene sheet to be used in the trial pressing method. Per box 1000 sheets. Before we are placing the flask with the dough under the hydraulic press, put a Divosheet over the dough in the flask. Than place the upper part of the flask and close the flask. Place the flask under the hydraulic press and slowly press the flask until the moment that all the rest dough came out. Remove the flask from the hydraulic press and open it again. Remove the Divosheet and the rest dough. Close the flask again and continue the pressing technique. By doing these steps in the process, the bite raise will be prevented.
