Pressboard

Pressboard is a class of cellulose-based material constructed of several layers (plies) of paper which, when compressed using a combination of heat and pressure, form a stiff, dense material in a range of weights.[1] Pressboard has been widely used in traditional school and office products such as spiral-bound notebooks and three-ring binders, but its unique physical characteristics lend itself readily to a variety of end-uses, including (but not limited to) document storage, filing supplies (classification and file folders), report covers, folding cartons, tags, labels, and industrial applications.[2][3][4] It is commonly used to make the back panels of radios and some televisions. Pressboard may be converted using a number of different techniques (scoring, folding, die-cutting), and accepts a range of value-add decorating techniques (coating, foil-stamping, screen-printing, and embossing). Pressboard may contain recycled fiber content (including post-consumer waste), and is typically itself recyclable and biodegradable, making it an environmentally-sound choice for those seeking an alternative to petroleum-derived substrates. Pressboard has also been made from cornstalks.[5]
