Rolls of Super Calendered Kraft

A Calender stack is a series of hard pressure rollers used to form or smooth a sheet of paper or plastic film. Known for its ultra smoothness and glossiness. This finishing or extra calendering is often done not in line and handled by a special machine dedicated to this type of calendering. The "supercalender" machine gives paper a high-gloss finish, depending on how long it is calendered for. A supercalender is a vertical alternating stack of hard polished steel and soft cotton (or other resilient material) rolls. The hard roll is pressed heavily against the soft roll, compressing the material. As the paper web passes through this nip, the force generated as the soft roll struggles to return to its original dimensions "buffs" the paper, generating the additional luster and enamel-like finish typical of supercalendered paper.

Glassine is manufactured within a narrow caliper tolerance and provide very good die-cutting principals. Glassines have a very low absorption tolerance, making them perfect for consistent silicone coating. Glassine offers many advantages in comparisons to other paper carriers, especially for double sided liners within a narrow release differential. See more details on Glassine by clicking here.
