Manila paper (Spanish : 'Papel de Manila') is a relatively inexpensive type of paper, generally made through a less-refined process than other types of paper, and is typically made from semi-bleached wood fibers.
The manila component of the name originates from manila hemp (a.k.a. abacá leaves), which was named after Manila, the capital of the Philippines. [1] Beginning in the 1840s, recycled abacá rope fibers were the main material for manila paper. [2]
Before the end of the 20th century,[ when? ] papermakers replaced the abacá fibers with wood pulp, [3] which cost less to source and process. [4] Despite the change in production material, "the name and color remain." [4]
Since at least 1915, manila paper has been shaped to create manila file folders and manila envelopes. [5]
It is just as strong as kraft paper but has better printing qualities, such as stronger pigment retention.[ citation needed ] Manila paper is buff-colored and the fibers of the paper are usually visible to the naked eye.[ citation needed ]
Some fashion schools and people in the fashion industry use large rolls of Manila to create finalised clothing patterns.[ citation needed ] Because the paper is generally inexpensive, it is commonly given to children for making art. [6]
In the 1830s, a cotton and linen rag shortage occurred in the United States. [7] This caused papermakers to seek out additional production materials. [8] This paper shortage "only abated in the 1870s, when rag paper was gradually replaced by paper made from wood pulp". [7]
In 1843, papermaker Mark Hollingsworth and his sons John and Lyman obtained a patent "to manufacture paper from manila fibers". [9] This family company became Hollingsworth & Vose. [9] The Guggenheim claims that this creation of manila paper was a way "of recycling manila rope, previously used on ships." [8] The resulting paper was strong, water-resistant, and flexible. [8]
Manila paper was originally made out of old Manila hemp ropes which were extensively used on ships, having replaced true hemp.[ citation needed ] The ropes were made from abacá or Musa textilis, which is grown in the Philippines. [10] Abacá is an exceptionally strong fibre, nowadays used for special papers like tea bag tissue.[ citation needed ] It is also very expensive, being several times more expensive than woodpulp, hence the change to that fiber for what is still called Manilla—usually with two L's.[ citation needed ] More recently[ when? ] new wood pulp has often been replaced with a high proportion of recycled fibers.[ citation needed ] True Manila hemp folders would have been much tougher and longer lasting than modern folders. [11]
By 1873, the United States Department of Agriculture quoted Thomas H. Dunham, who described Manila paper as "nine-tenths jute" when praising jute production. [12]
In 1906, over 2,000,000 piculs of manila fibers were produced, making approximately 66% of the country's export profits. [13]
From 1898 to 1946, the United States colonized the Philippines following the Spanish-American War. The Guggenheim claims the "colonial government found ways to prevent Filipinos from profiting off of the abaca crops, instead favoring the businesses of American expats and Japanese immigrants, as well as ensuring that the bulk of the abaca harvests were exported to the United States" for use in military initiatives.

A manila folder is a file folder designed to contain documents, often within a filing cabinet. It is generally formed by folding a large sheet of stiff card stock in half, sized so that full sheets of printer paper can fit inside without folding. Like manila envelopes, folders are traditionally buff, but other colors are occasionally used to differentiate categories of files.
The manila envelope, a close relative of the folder, often has a mechanism on the closing flap that allows it to be opened without damaging the envelope so that it can be reused. There are two main methods to achieve this. The first incorporates a metal clasp with two prongs, which are put through a reinforced eyelet in the flap and then bent apart to hold, while the other has a cardboard button secured tightly on the flap and a piece of string fastened on the envelope body (or the reverse arrangement) is wound around it to form a closure. In a more general sense, similar envelopes made of brown, unbleached paper, used for cheapness, are also described as manila envelopes.
Abacá (Spanish), Musa textilis, is a species of banana endemic to the Philippines. The plant grows to 13–22 feet (4.0–6.7 m), and averages about 12 feet (3.7 m). The plant, also known as Manila hemp, has great economic importance, being harvested for its fiber, also called Manila hemp, extracted from the leaf-stems.
Manila is the capital of the Philippines.
Papermaking is the manufacture of paper and cardboard, which are used widely for printing, writing, and packaging, among many other purposes. Today almost all paper is made using industrial machinery, while handmade paper survives as a specialized craft and a medium for artistic expression.
Pulp is a fibrous lignocellulosic material prepared by chemically, semi-chemically or mechanically producing cellulosic fibers from wood, fiber crops, waste paper, or rags. Mixed with water and other chemicals or plant-based additives, pulp is the major raw material used in papermaking and the industrial production of other paper products.
Kenaf [etymology: Persian], Hibiscus cannabinus, is a plant in the family Malvaceae also called Deccan hemp and Java jute. Hibiscus cannabinus is in the genus Hibiscus and is native to Africa, though its exact origin is unknown. The name also applies to the fibre obtained from this plant. Kenaf is one of the allied fibres of jute and shows similar characteristics.
Fiber crops are field crops grown for their fibers, which are traditionally used to make paper, cloth, or rope.
Hemp, or industrial hemp, is a plant in the botanical class of Cannabis sativa cultivars grown specifically for industrial and consumable use. It can be used to make a wide range of products. Along with bamboo, hemp is among the fastest growing plants on Earth. It was also one of the first plants to be spun into usable fiber 50,000 years ago. It can be refined into a variety of commercial items, including paper, rope, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food, and animal feed.
A manila folder is a file folder designed to contain documents, often within a filing cabinet. It is generally formed by folding a large sheet of stiff card in half. Though traditionally buff, sometimes other colors are used to differentiate categories of files.
Kraft paper or kraft is paper or paperboard (cardboard) produced from chemical pulp produced in the kraft process.
Cotton paper, also known as rag paper or rag stock paper, is made using cotton linters or cotton from used cloth (rags) as the primary material. Prior to the mid-19th century, cotton paper was the main form of paper produced, with pulp paper replacing cotton paper as the main paper material during the 19th century. Although pulp paper was cheaper to produce, its quality and durability is significantly lower. Although pulp-paper quality improved significantly over the 20th century, cotton paper continues to be more durable, and consequently important documents are often printed on cotton paper. Different grades of cotton paper can be produced.
Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, rags, grasses, or other vegetable sources in water, draining the water through a fine mesh leaving the fibre evenly distributed on the surface, followed by pressing and drying. Although paper was originally made in single sheets by hand, almost all is now made on large machines—some making reels 10 metres wide, running at 2,000 metres per minute and up to 600,000 tonnes a year. It is a versatile material with many uses, including printing, painting, graphics, signage, design, packaging, decorating, writing, and cleaning. It may also be used as filter paper, wallpaper, book endpaper, conservation paper, laminated worktops, toilet tissue, currency, and security paper, or in a number of industrial and construction processes.
Tree-free paper, or tree-free newsprint, is described as an alternative to wood-pulp paper due to its raw material composition. It is claimed to be more eco-friendly when considering the product's entire life cycle.
Deinking is the industrial process of removing printing ink from paperfibers of recycled paper to make deinked pulp.
Paper is a thin nonwoven material traditionally made from a combination of milled plant and textile fibres. The first paper-like plant-based writing sheet was papyrus in Egypt, but the first true papermaking process was documented in China during the Eastern Han period, traditionally attributed to the court official Cai Lun. This plant-puree conglomerate produced by pulp mills and paper mills was used for writing, drawing, and money. During the 8th century, Chinese paper making spread to the Islamic world, replacing papyrus. By the 11th century, papermaking was brought to Europe, where it replaced animal-skin-based parchment and wood panels. By the 13th century, papermaking was refined with paper mills using waterwheels in Spain. Later improvements to the papermaking process came in 19th century Europe with the invention of wood-based papers.
Wood-free paper is paper created exclusively from chemical pulp rather than mechanical pulp. Chemical pulp is normally made from pulpwood, but is not considered wood as most of the lignin is removed and separated from the cellulose fibers during processing, whereas mechanical pulp retains most of its wood components and can therefore still be described as wood. Wood-free paper is not as susceptible to yellowing as paper containing mechanical pulp. Wood-free paper offers several environmental and economic benefits, including reduced deforestation, decreased energy consumption, and improved waste management. The term Wood-free paper can be rather misleading or confusing for someone unfamiliar with the papermaking process because paper is normally made from wood pulp derived from trees and shrubs. However, wood free paper does not mean that the paper in question is not made from wood pulp but it means that the lignin in the wood fiber has been removed by a chemical process.
The History of Papermaking in New York had its beginnings in the late 18th century, at a time when linen and cotton rags were the primary source of fibers in the manufacturing process. By 1850 there were more than 106 paper mills in New York, more than in any other state. A landmark in the history of papermaking in the United States was the installation of the first Fourdrinier machine in the country at a mill in Saugerties, New York, in 1827. Papermaking from ground-wood pulp began in New York in 1869, with the establishment of the Hudson River Pulp & Paper Company in Corinth and also with the work of Illustrious Remington and his sons in Watertown. The innovation and success of the Remingtons spurred further development of the industry in the state.
Hollingsworth & Vose Company (H&V) is a global manufacturer of nonwoven materials and engineered papers used in filtration, energy, and industrial applications. The firm is a privately held business founded in 1843; its headquarters are in East Walpole, Massachusetts, USA.
Shives, also known as shoves, boon or hurd, are the wooden refuse removed during processing flax, hemp, or jute, as opposed to the fibres (tow). Shives consist of "the woody inner portion of the hemp stalk, broken into pieces and separated from the fiber in the processes of breaking and scutching" and "correspond to the shives in flax, but are coarser and usually softer in texture". Shives are a by-product of fiber production.
Hemp paper is paper varieties consisting exclusively or to a large extent from pulp obtained from fibers of industrial hemp. The products are mainly specialty papers such as cigarette paper, banknotes and technical filter papers. Compared to wood pulp, hemp pulp offers a four to five times longer fibre, a significantly lower lignin fraction as well as a higher tear resistance and tensile strength. Because the paper industry's processes have been optimized for wood as the feedstock, production costs currently are much higher than for paper from wood.
The Paper Mill Homburg, built in 1807, is located in Triefenstein-Homburg am Main. It was used until 1975 for the commercial production of paper and cardboard and was renovated 1994 to 1997 as a paper mill museum. The production facilities with original machines and equipment are preserved.
