Product type
Softwood Kraft Pulp is a type of pulp produced from softwood trees, primarily conifers like pine and spruce. It is created through the Kraft process, which involves cooking wood chips in a chemical solution to break down the lignin and separate the cellulose fibers. This results in a strong and durable pulp that is ideal for various paper products. Softwood Kraft Pulp is known for its long fiber length, which contributes to the strength and quality of the final paper products.
| Fiber length | Long fibers typically ranging from 2 to 5 mm |
| Brightness | Usually between 85% to 90% |
| Moisture content | Typically 8% to 10% |
| Kappa number | Generally between 15 to 30 |
| pH level | Typically between 4.5 to 7.5 |
When selecting Softwood Kraft Pulp, buyers should consider the desired fiber length and strength for their specific paper applications. It is also important to specify the required brightness and moisture content to ensure optimal performance in the production process. Certifications such as sustainable sourcing or environmental standards may be relevant, depending on the buyer's requirements. Quantities should be clearly stated to facilitate accurate quotes.
