Wood is the principal source of cellulosic fiber for pulp and paper manufacture. At present, wood provides about 90% to 95% of the world’s virgin fiber requirement. For paper technologists and mill chemists, understanding the raw material at a cellular level is not just academic—it is essential for optimizing the pulping process. A tree can … Read more
Cellulosic fibers are the fundamental building blocks of the global paper and pulp industry. Extracted primarily from plant life and wood, these natural polymers possess a unique combination of physical and chemical characteristics that make them exceptionally suited for forming durable, versatile networks. Cellulosic fibers exhibit a number of properties which fulfill the requirements of … Read more
When you hold a sheet of paper, you aren’t just holding a flattened mat of wood; you are holding a triumph of chemical engineering. For professionals in the pulp and paper industry, understanding fiber chemistry is not just academic—it is the difference between a high-performance packaging grade and a web break on the machine. At … Read more
The pulp and paper industry has shaped human civilization for nearly 2,000 years. Understanding the milestones in pulp and paper industries development isn’t just a look back at history; it’s a roadmap for the future of sustainable manufacturing. As we move through 2026, the industry is undergoing another radical shift—transitioning from mass production to “smart” … Read more
Paper is everywhere—books, packaging, tissues, photocopy sheets, newsprint, paper cups, and even specialty industrial applications. But behind every sheet of paper lie microscopic fibers that determine its strength, texture, brightness, and durability. These fibers can come from trees, plants, recycled paper, and even textile waste. As sustainability becomes a global priority, understanding the sources of … Read more
Paper touches nearly every part of modern life—books, packaging, tissues, cartons, food boxes, office sheets, and more. But few people understand what “pulp,” “paper,” and “paperboard” actually mean or how they differ. This article breaks down these essential materials in a clear, simple way. Whether you’re a student, buyer, manufacturer, or sustainability researcher, you’ll find … Read more
When it comes to packaging delicate items like clothing, artwork, collectibles, or archival documents, not all tissue papers are the same. One type stands out for its protective and long-lasting qualities — acid-free tissue paper. It has become an essential material for museums, fashion retailers, e-commerce brands, and even eco-conscious consumers who care about both … Read more
A drum chipper reduces logs, slabs, edgings, and waste wood into uniform chips by cutting against a fixed counter-knife (anvil) with knives mounted on a large rotating drum (rotor). Compared with disc chippers, drum machines are prized for very high throughput, broad infeed acceptance, and robust handling of variable wood forms—from whole logs to sawmill … Read more
The chipping process in papermaking is a vital early stage in transforming raw wood into pulp—the foundation for paper production. Uniform wood chips promote efficient pulping and result in superior paper quality. This article explores each phase, including raw materials, debarking methods, log cutting, chippers (disc, drum, screw), screening, and the conveyors that tie it … Read more
