Blue Denim Paper
100% cotton based roll cover material suitable for high speed, high line pressure supercalendering.
Typical Uses
- Magazine/SC paper
- Coated paper
- LWC paper
Key Features
- Accurate nip profile and surface smoothness produce excellent and consistent paper quality
- Relative resistance to burning compared to other standard filling materials
- Performs well in high production volume supercalendering applications
Blue Denim Paper is a 100% cotton based filling material produced from blue denim cotton fibres. Its relatively narrow nip width and high specific nip pressure result in suitability for high production volume supercalendering applications. The accurate nip profile and surface smoothness characteristics of Blue Denim Paper rolls enhance final paper quality. Regrinding is required at regular intervals to maintain a surface free from marking and high density spots. Temperature tolerance is higher than filling materials produced from cotton / wool combination materials due to narrow nip width resulting in lower heat generation.
The performance of Blue Denim Paper rolls can be improved through RHL’s unique Roll Conditioning service. This extra service is designed to enable the rolls to withstand more extreme running conditions with resulting improved life and performance.
