Types of Paper Media
Paper is often characterized by weight. The weight assigned to a paper is the weight of a ream (500 sheets) of varying “basic sizes”, before the paper is cut into the size it is sold to end customers.
Density of Paper:The density of paper ranges from 250 kg/m3 (16 lb/ft3) for tissue paper to 1500 kg/m3 (94 lb/ft3) for some speciality paper. Printing paper is about 800 kg/m3 (50 lb/ft3).

Bank paper is a thin strong writing paper of less than 50g/m2 commonly used for typewriting and correspondence.
Bond paper is a high quality durable writing paper similar to bank paper but having a weight greater than 50 g/m2.It is used for letterheads and other stationery and as paper for electronic printers. Widely employed for graphic work involving pencil, pen and felt-tip marker. It is largely made from rag pulp which produces a stronger paper than wood pulp.
A book paper (or publishing paper) is a paper which is designed specifically for the publication of printed books. Traditionally, book papers are off white or low white papers (easier to read), are opaque to minimize the show through of text from one side of the page to the other and are (usually) made to tighter caliper or thickness specifications, particularly for case bound books. Typically, books papers are light weight papers 60 – 90gsm and often specified by their caliper/substance ratios (volume basis).
Construction Paper / Sugar Paper
Construction paper or sugar paper, is a type of coarse colored paper typically available in large sheets. The texture is slightly rough, and the surface is unfinished. Due to the nature of the source material from which the paper is manufactured, small particles are visible on the paper’s surface.
Cotton paper is made from 100% cotton fibers. Cotton paper is superior in both strength and durability to wood pulp-based papers, which may contain high concentrations of acids.May also be known as cotton rag or ragged paper.
Cotton fiber papers is known to last several hundred years without fading, discoloring, or deteriorating; so is often used for important documents such as the archival copies of dissertation or thesis. As a rule of thumb, each percentage point of cotton fiber, a user may expect one year of resisting deterioration by use (the handling to which paper may be subjected).(reference – Southwest Paper Co). Legal document paper typically may contain 25% cotton.Cotton paper is also used in banknotes.
Electronic Paper/ E- Paper
Electronic Paper is a display technology designed to mimic the appearance of ordinary ink on paper.Electronic paper reflects light like ordinary paper and is capable of holding text and images indefinitely without drawing electricity, while allowing the image to be changed later.E-paper can be crumpled or bent like traditional paper. Pixels on e-paper are image stable, or bistable, so that the state of each pixel can be maintained without a constant supply of power.
Inkjet paper is paper designed for inkjet printers, typically classified by its weight, brightness and smoothness, and sometimes by its opacity.
Photo paper is a category of inkjet paper designed specifically for reproduction of photographs. The best of these papers, with suitable pigment-based ink systems, can match or exceed the image quality and longevity of traditional materials used for printing color photographs, such as Fuji CrystalArchive (for color prints from negatives) and Cibachrome/Ilfochrome (for color prints from positive transparencies). For printing monochrome photographs, traditional silver-based papers are widely felt to retain some advantage over inkjet prints.
Kraft paper is paper produced by the Kraft process from wood pulp. It is strong and relatively coarse. Kraft paper is usually a brown colour but can be bleached to produce white paper. It is used for paper grocery bags, multiwall sacks, envelopes and other packaging.
Laid paper is a type of paper having a ribbed texture imparted by the manufacturing process.Laid paper is still commonly used by artists as a support for charcoal drawings.
Tyvek / Tyvex
Tyvek is a brand of flash spun high-density polyethylene fibers, a synthetic material; the name is a registered trademark of the DuPont Company. The material is very strong; it is difficult to tear but can easily be cut with scissors or any other sharp object. Water vapor can pass through Tyvek, but not liquid water, so the material lends itself to a variety of applications: medical packaging, envelopes, car covers, air and water intrusion barriers (housewrap) under house siding, labels, wristbands, mycology, and graphics. Tyvek is sometimes erroneously referred to as “Tyvex.”
A paper towel is a disposable product made of paper. It serves the same general purposes as conventional towels, such as drying hands, wiping windows and dusting. Because paper towels are disposable, they are often chosen to avoid the contamination of germs.
Wallpaper is material which is used to cover and decorate the interior walls of homes, offices, and other buildings; it is one aspect of interior decoration. Wallpapers are usually sold in rolls and are put onto a wall using wallpaper paste.Wallpapers can come either plain so it can be painted or with patterned graphics. Wallpaper printing techniques include surface printing, gravure printing, silk screen-printing, and rotary printing.”Wallpaper” is also a term for computer wallpaper.
Washi or Wagami is a type of paper made in Japan. Washi is commonly made using fibers from the bark of the gampi tree, the mitsumata shrub (Edgeworthia papyrifera), or the paper mulberry, but also can be made using bamboo, hemp, rice, and wheat. Washi comes from wa meaning Japanese and shi meaning paper, and the term is used to describe paper made by hand in the traditional manner.Washi is generally tougher than ordinary paper made from wood pulp, and is used in many traditional arts.
Wax paper (also called waxed paper) is a kind of paper that is made moisture proof through the application of wax.The practice of oiling parchment or paper in order to make it semi-translucent or moisture-proof goes back at least to medieval times. Thomas Edison claimed to have invented wax paper in 1872, but what he really invented was a cheap and efficient means to manufacture such paper.Wax paper is commonly used in cooking, for its non-stick properties, and wrapping food for storage, as it keeps water out or in. It is also used in arts and crafts.
Wove paper is a writing paper with a uniform surface, not ribbed or watermarked.
Coated paper is paper which has been coated by an inorganic compound to impart certain qualities to the paper, including weight and surface gloss, smoothness or ink absorbency. Kaolinite is the compound most often used for coating papers used in commercial printing. One function of coating is to protect against ultraviolet radiation.
