White top linerboard is a type of paper that is specifically designed for demanding printing jobs. It is characterized by its smoothness and attractive appearance on the top surface. The basis weight for the top ply, or layer, of the linerboard typically ranges from 70-80 grams per square meter. In order to achieve the desired level of quality, bleached chemical pulp is used as the main component for the top ply.

One crucial factor in producing high-quality white top linerboard is the formation of the top ply. Formation refers to the uniform distribution of fibers within the paper, and it plays a vital role in determining the paper’s visual appearance. To achieve excellent formation, it is important to use hardwood pulp as the primary component of the top ply.

In addition to the choice of pulp, filler is often used in the top ply to improve the opacity of the paper. Opacity refers to the paper’s ability to prevent the transmission of light, and it is particularly important for achieving a clean and vibrant print. By using filler, the top ply becomes more opaque, ensuring that the ink does not bleed through and maintaining a high level of print quality.

Furthermore, the use of filler in the top ply also enhances the overall appearance of the white top linerboard. The added opacity helps to create a more visually appealing surface, making it ideal for printing jobs that require sharp and detailed images or text. With improved opacity, the white top linerboard provides a clean and crisp canvas for any printed design.

Overall, white top linerboard is specifically engineered for demanding printing jobs that require a high level of smoothness and visual appeal. By using bleached chemical pulp as the main component and incorporating filler to improve opacity, the top ply of the linerboard ensures excellent formation and an attractive surface. Whether it is for packaging, displays, or any other printing application, white top linerboard is the perfect choice for achieving outstanding print quality.
