Natural pulp from wood unbleached virgin hardwood pulp sheet board

Hardwood pulp board is a type of pulp from wood trees, which are typically deciduous trees such as oak, maple, birch, and beech. 

The unbleached wood pulp 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 pulp is shorten than softwood pulp. Hardwood pulp is often mixed with softwood pulp or bamboo pulp, derived from coniferous trees, to achieve desired properties in the final product.

Packing: packed in bale with iron wire.

840*700*520mm/pack, 1400*840*1800mm/bale, around 1.98 tons/ bale.

What is unbleached pulp from wood used for?

Unbleached pulp from wood, produced through the kraft pulping process without undergoing bleaching, finds applications in various industries due to its specific characteristics. 

1. Packaging Materials: Unbleached hardwood 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 hardwood 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 hardwood pulp board due to its natural color and cost-effectiveness.

7. Art and Craft: Unbleached hardwood 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.
