Hard wood pulp board is a type of pulp produced from hardwood trees, which are typically deciduous trees such as oak, maple, birch, and beech. We use chemical pulping method to produce kraft wood pulp.
The natural wood pulp board is commonly used in the production of paper, cardboard, and other cellulose-based products due to its strength, durability, and versatility.
The fiber length of hardwood kraft pulp is shorten than softwood kraft pulp. Hardwood pulp is often mixed with softwood pulp or bamboo pulp, derived from coniferous trees, to achieve desired properties in the final product.
The hard wood pulp board is in sheet form. It is packed in bale with iron wire.
Packing: 840*700*520mm/pack, 1400*840*1800mm/bale, around 1.98 tons/ bale.
Free sample: Available.

Application
Unbleached hardwood pulp, produced through the kraft pulping process without undergoing bleaching, finds applications in various industries due to its specific characteristics. Some common applications of unbleached hardwood pulp include:
1. Packaging Materials: Unbleached hard wood pulp board is commonly used in the production of packaging materials such as corrugated cardboard, linerboard, and containerboard. Its strength and durability make it suitable for protecting goods during shipping and handling.
2. Industrial Papers: It is used in the manufacture of industrial papers such as Kraft paper and sack paper. These papers are used for wrapping, packaging, and as liners for various industrial products due to their strength and tear resistance.
3. Composite Panels: Unbleached hardwood pulp can be used as a component in the production of composite panels, such as particleboard and medium-density fiberboard (MDF), providing structural strength and stability.
4. Absorbent Products: In industries such as automotive and construction, unbleached hardwood pulp is utilized in the production of absorbent materials like insulation products and acoustic panels due to its absorbency and insulating properties.
5. Environmental Applications: Unbleached hard wood pulp board is sometimes used in environmental applications such as in the creation of biodegradable products or as a component in soil erosion control products.
6. Specialty Papers: Some specialty papers, particularly those where color consistency is not critical, may utilize unbleached hard wood pulp board due to its natural color and cost-effectiveness.
7. Art and Craft: Unbleached hard wood pulp board can also be used in various art and craft applications where its natural color and texture are desirable characteristics.
Unbleached hardwood pulp offers a cost-effective and environmentally friendly option for applications where the absence of bright white color is not a requirement, and strength and durability are essential.
What is called wood pulp?
Wood pulp, simply put, refers to the fibrous material derived from wood through mechanical or chemical processes. It’s the primary raw material used in the production of paper and a wide range of other products. Wood pulp can be categorized into two main types based on the source of the wood: hardwood pulp and softwood pulp.
Hardwood pulp is derived from deciduous trees, such as oak, maple, birch, and beech, while softwood pulp comes from coniferous trees like pine, spruce, fir, and cedar. Wood pulp is processed into various grades and qualities depending on the desired characteristics of the end product, such as strength, smoothness, opacity, and absorbency. It’s a versatile material used in industries ranging from papermaking to textiles, packaging, and beyond.
