Cartonboard is a type of stiff paperboard that is characterized by its strength, rigidity, and resistance to bending or folding. It is commonly used for manufacturing various types of cartons, packaging materials, and boxes, due to its durability and versatility.
Typically made from a combination of recycled paper and wood pulp, cartonboard is manufactured through a process called papermaking. The fibers are extracted from the raw materials and then mixed with water to create a pulp, which is then refined and filtered to remove impurities. Afterward, the pulp is rapidly dried and pressed to form solid sheets of cartonboard.
The thickness of cartonboard can vary depending on its intended use; however, it generally falls within the range of 200 to 600 grams per square meter. This thickness ensures that it provides adequate protection and support to the products it carries.
Cartonboard is known for its excellent printing and graphics capabilities, allowing it to be easily decorated with vibrant colors and designs. It also possesses high tensile strength, enabling it to resist tearing and creasing. Moreover, cartonboard can be coated or laminated, enhancing its appearance and providing additional protection against moisture, grease, and other external factors.
Due to its eco-friendly nature, cartonboard is increasingly favored as a sustainable packaging solution. It is recyclable and biodegradable, thus minimizing its impact on the environment. Additionally, its versatility and versatility make it an ideal choice for a wide range of applications in industries such as food and beverage, cosmetics, electronics, and more.
