Kraft Liner Board
Kraft liner board, often referred to simply as "kraft liner," is a type of paperboard known for its strength, durability, and versatility. It is widely used in the packaging industry, particularly for the production of corrugated boxes and other packaging materials. Here's some information about kraft liner boards Kraft liner board is a high-strength paperboard primarily made from long fibers of softwood pulp, typically derived from pine and spruce trees. The term "kraft" is derived from the German word for "strong" or "sturdy," reflecting its robust nature. Kraft liner is typically brown or tan in color due to its unbleached fibers.
Key Characteristics of Kraft Liner Board
High Strength
Kraft liner board is known for its excellent tensile and burst strength, making it ideal for applications where durability and resistance to tearing or puncturing are essential.
Two Types
There are two main types of kraft liner board: kraft linerboard (KLBD) and kraft top liner (KTL). KLBD is used for the inner layer of corrugated boxes, while KTL, which is typically coated, serves as the outer liner for improved printability.
Sustainable Sourcing
Like other paper-based materials, kraft liner board is highly recyclable, contributing to its sustainability as a packaging option.
Recyclability
Many manufacturers of kraft liner board prioritize using sustainably sourced wood fibers and adhere to responsible forestry practices.
Applications of Kraft Liner Board
