Tree-free paper, also known as no tree paper, offers an alternative to traditional wood-pulp paper [1] due to its unique raw material [2] composition. This type of paper is considered more eco-friendly especially when evaluating its entire life cycle. Sources of fiber for tree-free paper [3] [4] [5] Tree-free paper fibers are derived from ...
Wood-free paper is used in a variety of applications: Writing and printing papers: Wood-free paper is the most common type of paper used for writing and printing. [23] It is available in a variety of weights and finishes, making it ideal for a variety of applications [17] Envelopes: Wood-free paper is the most common type of paper used for ...
The end paper product (paper, paperboard, tissue, cardboard, etc.) dictates the species, or species blend, that is best suited to provide the desirable sheet characteristics, and also dictates the required fibre processing (chemical treatment, heat treatment, mechanical "brushing" or refining, etc.).
Offset paper is a WFU paper with ISO brightness > 80% and a basis weight of 40–300 g/m 2. Surface strength and low linting are the main parameters, but brightness and opacity are also important. Surface strength and low linting are the main parameters, but brightness and opacity are also important.
Since dissolving pulp is highly refined, it is a product of high whiteness with few impurities making it suitable in specialty paper-related products such as filter paper and vulcanized fibre. Cellulose powder is dissolving pulp that has undergone acid hydrolysis, been mechanically disintegrated and made into fine powder.

In the 1965 Post’s Pulp and Paper Directory, National Vulcanized Fibre Co. was listed as having two mills' producing rag paper for vulcanized fibre. They were at Newark, producing 15 tons a day; and Yorklyn, producing 18 tons a day. This compares with Spaulding Fibre’s Tonawanda plant, then producing 40 tons a day (Post’s directory).
Fiber crops are generally harvestable after a single growing season, as distinct from trees, which are typically grown for many years before being harvested for such materials as wood pulp fiber or lacebark. In specific circumstances, fiber crops can be superior to wood pulp fiber in terms of technical performance, environmental impact or cost. [2]
