CCWB (Clay Coated White Back)
CCWB (Clay Coated White Back) board is a type of paperboard that has a grey core and white surface and back layers. The white surface layer of the paperboard is made up of fillers and adhesives, and is coated with a certain amount of coating. The paperboard is then passed through multiple rollers to achieve a smooth and tight texture, with a uniform thickness.It has following features:
- Grey core and white surface and back layers
- Tight and uniform texture
- Very white and smooth surface with uniform ink absorption
- Less prone to powdering and shedding
- Strong and tough texture with good folding resistance
- Excellent printability due to its porosity structure, ink absorption, surface smoothness
CCWB paperboard is a cost-effective and sustainable packaging material that offers good stiffness and strength. CCWB paperboard is suitable for a variety of printing techniques, making it a versatile choice for both primary and secondary packaging applications.
The printability of CCWB paperboard depends on several factors, including the porosity structure and ink absorption of the paper, the smoothness and compressibility of the paper surface, the surface strength of the paper, the acidity and alkalinity of the paper, as well as the water content and stretchability of the paper.
The properties of CCWB paper must reflect the best printing quality and color effects. During the rotation of the printing cylinder, the ink adhered to the printing plate can be smoothly transferred to the surface of the paper, resulting in complete, full, clear and rich graphic prints. It's an ideal choice for a wide range of packaging applications where high-quality printing and visual appeal are important. CCWB paperboard is also environmentally friendly and recyclable.
