Pressboard
Pressboard is a class of cellulose-based material constructed of several layers of paper which, when compressed using a combination of heat and pressure, form a stiff, dense material in a range of weights. 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 document storage, filing supplies, report covers, folding cartons, tags, labels, and industrial applications. It is commonly used to make the back panels of radios and some televisions. Pressboard may be converted using a number of different techniques, and accepts a range of value-add decorating techniques. Pressboard may contain recycled fiber content, and is typically itself recyclable and biodegradable, making it an environmentally-sound choice for those seeking an alternative to petroleum-derived substrates.
