卷筒玻璃纸按基本用途分为两类：一类是下机卷筒纸，即在玻璃纸生产线切边后直接卷取下机。另一类是用于印刷复合的高档卷筒玻璃纸，除具有平板玻璃纸的功能外，卷筒玻璃纸的显著特点是幅间差小，厚度更加均匀，表面经过特殊处理，更加适用于印刷和复合。

Roll cellophane we produced is divided into two types in 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. thickness and the min. thickness of the film; and that it is more suitable for printing and laminating because of the special surface treated by special processes.
