Unbleached softwood pulp kraft wood pulp material

Softwood pulp is extracted from softwood trees, primarily coniferous trees such as pine, spruce, fir, and hemlock. Softwood trees have longer, straighter fibers compared to hardwood trees, which typically have shorter and more irregular fibers.

Softwood pulp is known for its strength, long fibers, and high cellulose content, making it particularly suitable for applications where strength and durability are important, such as in the production of packaging materials, paperboard, and specialty papers like high-quality printing papers.

The wood pulp 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.

What are the softwoods used in paper industry?

In the paper industry, several types of wood for paper making. Some of the main paper pulp tree species utilized include:

1. Pine: Pine trees are widely used in the paper industry due to their abundance and favorable fiber characteristics. Varieties such as Scots pine, Eastern white pine, and Southern yellow pine are commonly utilized.

2. Spruce: Spruce trees, particularly species like Norway spruce and Sitka spruce, are valued for their long, slender fibers, which contribute to the strength and smoothness of paper products.

3. Fir: Fir trees, including species like Douglas fir and balsam fir, are another important source of softwood pulp. They provide fibers with good strength properties, suitable for various paper grades.

4. Hemlock: Hemlock trees, such as Eastern hemlock and Western hemlock, are also used in the paper industry. Hemlock fibers are known for their strength and versatility in papermaking.

These softwood species are processed into pulp and the resulting pulp is utilized in the production of a wide range of paper and paperboard products, including newsprint, packaging materials, printing papers, and specialty papers.
