Mottled linerboard is a type of packaging material that is commonly used to create boxes and other containers. What sets it apart from other types of linerboard is its distinctive appearance, which gives it a flocky or speckled look. This appearance is achieved through the use of a top ply made of bleached pulp.

The top ply of mottled linerboard is made from bleached pulp, which gives it a bright, white color. This is in contrast to the bottom ply, which is typically made from recycled paper fibers and has a more natural, brownish color. The top ply basis weight of mottled linerboard is roughly 40 g/m2, which is relatively low compared to other types of linerboard.

The low top ply basis weight is what gives mottled linerboard its flocky appearance. Because the top ply is lighter in weight, it creates a more open and porous surface. This allows for the formation of small, irregularly shaped spots or specks on the surface of the linerboard. These spots or specks give the material its unique and eye-catching appearance.

In addition to its distinctive appearance, mottled linerboard also offers a range of other benefits. For one, it is an environmentally friendly option, as it is made from recycled paper fibers. This makes it a popular choice among businesses and consumers who are looking to reduce their environmental impact.

Mottled linerboard is also known for its strength and durability. Despite its relatively low basis weight, it is able to provide a high level of protection for packaged goods. This makes it suitable for a wide range of applications, including shipping boxes, retail packaging, and more.

Furthermore, mottled linerboard is highly versatile and can be easily customized to meet specific packaging needs. It can be printed on, laminated, or coated to enhance its appearance or provide additional functionality. This makes it a popular choice for businesses that want to create unique and eye-catching packaging designs.

In conclusion, mottled linerboard is a unique and versatile packaging material that offers both aesthetic appeal and practicality. Its flocky appearance, achieved through the use of a low top ply basis weight of bleached pulp, makes it stand out from other types of linerboard. With its strength, durability, and customizability, mottled linerboard is a great choice for businesses looking to create eye-catching and environmentally friendly packaging solutions.
