Industrial paper-primarily in the form of paperboard-serves as a base material for manufacturing packaging products such as shipping cartons, folding boxes, and paper cups. It requires further processing to create finished goods and is widely used in sectors including logistics, food packaging, and construction protection. Common varieties include kraft paperboard, corrugating medium, and coated white-top board; kraft paperboard, for instance, combines unbleached sulfate wood pulp on the surface with recycled pulp, offering high compressive strength and excellent printability, while corrugating medium is made from semi-chemical pulp and typically forms the fluted layer of corrugated board.
Industrial papers are tailored to specific industrial applications based on their structural and manufacturing characteristics; for example, coated white-top board-processed with bleached pulp-offers the whiteness and ply bond strength required for food packaging, whereas greyboard and roofing felt base paper are often produced from recycled pulp to meet waterproofing and protective layering needs. Specialized functional products include high-temperature insulation paper and cleanroom wiping paper, utilized in electronics, apparel, and equipment maintenance. Strict moisture protection is required during transport to prevent paper damage and associated economic losses.
