Challenges in Winding Flexible Packaging Film
www.tappi.orgtoo tightly will “block”. Roll blocking is a defect where the sheet layers fuse or adhere together. When winding extensible film on thin wall cores, winding hard rolls can cause the cores to collapse. This can cause problems in removing the shaft, or with inserting the shaft or chucks on the subsequent unwinding operation.

pn.bmj.comMay 31, 2015 · density is at its highest. The visual sensitiv-ity slopes off further from the fovea. This drop in sensitivity can be visualised as a hill, with the fovea is at the peak (figure 1). Conventional perimetry is carried out under photopic (well lit) conditions, and therefore, rod photoreceptors do not con-tribute to the findings. 2.
