17Paper and Paper Products Industry

These products are grouped together because they are part of a related processing chain. Often, more than one operation is involved in a single unit. Pulping involves separating cellulose fibers from other substances in wood, or dissolving and deinking waste paper, and mixing small amounts of reagents to strengthen the fiber bonds. Processed paper products are made from paper and other materials using a variety of techniques. Paper products can include printed materials (e.g., wallpaper and wrapping paper), as long as printing is not essential to their manufacture. The production of pulp, paper, and paperboard is included in group 170, while the remaining groups include the production of paper products and further processed paper.
