Roll cellophane,with substance  range of 28g-56g/m2 we produce is divided into two types terms of use purposes: one type is the mill-roll cellophane, which is directly wound into roll after being cut off the edges of film at the end of production machine; the other is the roll cellophane for printing and laminating.Besides the basic properties of PT-cellophane in sheet,the most important properties of the latter kind of roll cellophane are that its thickness is much more even than sheet cellophane along the whole width direction because of the little difference between the max.thckness and the min.thckness of the film;and that it is more suitable for printing and laminatiog because of the special surface treated by special processes.
