PermaSafety is sturdy, uniform (homogeneous) product from “virgin” plastic. Since PermaSafety is so thick (1 mm of plastic with additional 160μm glue) has on the sides chamfered edges to prevent lifting and jamming. Each roll is made individually. Each width requires its own very expensive machine to manufacture, so we have a width of 50mm, 75mm and 100mm. The upper surface is finished with a mild anti-skid textured or smooth surface, easy to clean.
