British Columbia’s (B.C.) solid wood and pulp and paper industries complement each other. Fibre for pulp and paper production comes from residual sawmill chips and logs. B.C. wood fibre supply for pulp and paper comes from a variety of wood species.

Due to the climatic conditions in B.C., many of these species naturally develop long, slender and thin-walled fibres. These fibre properties result in pulps, particularly kraft pulps, that have excellent tensile strength properties, suitable for reinforcing a wide range of paper and tissue products and maximizing operating efficiencies on paper machine and converting equipment. 
 

Market Pulp

B.C. mills produce pulp from local softwood species from the province’s sustainably managed forests. As a result, B.C. pulp is in demand worldwide for its superior ability to produce a wide range of high-quality paper products. Examples include magazines, specialty and writing papers, tissues, paper towels, newsprint and containerboard.

Kraft Pulp – Northern Bleached Softwood Kraft (NBSK)

The kraft process is a chemical pulping process that makes a very strong pulp. The chemicals used for pulping are recovered and reused, making the process very efficient. NBSK is used by paper manufacturers to produce a variety of paper products, including tissue grades, printing and writing papers, lightweight coated papers for catalogues, magazines and speciality papers.

This pulp is popular due to its diversity of applications, for its strength and other functional advantages. The fibre used to make kraft pulp is mainly made of leftover material from B.C. lumber mills that would otherwise be wasted. The versatile fibre properties of bleached pulp make it suitable for use in the manufacturing of a wide variety of products, especially those requiring the highest tensile strength.

Kraft Pulp – Northern Softwood Kraft (NSK)

Unbleached NSK is a strong pulp, used for kraft and wrapping papers, specialty papers and linerboard. Special high purity unbleached kraft pulp is used in electrical insulation applications.

Bleached Chemi-Thermo Mechanical Pulp (BCTMP)

This pulping process applies heat, chemicals and a refining process to make BCTMP in a non-chlorine environment. B.C. softwood BCTMP is used for manufacturing products such as coated board grades, printing and writing paper, and paper towel and napkin grades. Hardwood BCTMP is suitable for the production of coated board grades, printing and writing papers. 

Dissolving Pulp

Dissolving pulps are bleached chemical pulps composed mainly of pure cellulose (90 percent alpha-cellulose and over), that are used to manufacture various cellulose-derived products. B.C.’s western hemlock species is particularly well suited to making dissolving pulp.

Different dissolving pulp grades vary in purity depending on end-use. They are used principally as a source of cellulose in the manufacturing of products such as synthetic fibres such as rayon, plastic materials, lacquers and explosives.

Paper

B.C. produces a wide range of high-quality paper products from softwood species indigenous to B.C. Paper, one of wood’s oldest uses, is used for writing, printing, and for packaging, health and sanitary products, as well as many industrial processes. Recycled paper is made of reconstituted de-inked pulp and composites. Paper is also increasingly used as a green packaging material, a renewable alternative to fossil fuel-based packaging (plastics and foams).

Mechanical printing papers contain mechanical pulps such as Thermo-Mechanical Pulp or Chemi-Thermo-Mechanical Pulp. Some mechanical printing papers contain a small amount of kraft pulp for extra strength.

Newsprint

Newsprint is an uncoated mechanical paper mainly used in the printing of newspapers. It is primarily made of mechanical pulp and can contain recycled fibre from old newspapers and magazines. 

Uncoated mechanical papers

Uncoated papers, excluding newsprint, are composed of fibres mainly from mechanical pulping. They are used for inserts, flyers, magazines, catalogues, directories and books. 

Lightweight coated papers

Lightweight coated papers can be gloss or matte finish, and come in a variety of weights for printing magazines, catalogues, inserts/flyers, supplements and promotional materials. 

Kraft papers

Kraft papers are made predominantly from wood pulp. They are noted for their strength and, in unbleached grades, used primarily as wrappers and packaging materials. They can be converted into grocery bags, multi-wall sacks, tire wraps and butchers wraps. 

Containerboard

Component materials such as linerboard and corrugated medium are used in the manufacture of shipping containers, other corrugated board products, specialty liners and fibre boards. 

Tissue

Tissue grades, manufactured from kraft and recycled pulp, include bathroom and facial tissue, paper towels and napkins. They are manufactured for consumer, in-home and commercial use and away-from-home use, such as office and industrial buildings, schools and hotels.
