Cardboard

== Description ==
The standard definition is a stiff pasteboard that is thicker than 0.006 inches. However, over the years, the term 'cardboard' has been used for many materials that vary greatly in type and stability. Early cardboards and most current brown cardboards are produced from wood pulp or recycled papers and as such often contain high amounts of lignin with acidic pH levels. High quality archival cardboard, also called Pasteboards, are made from rag pulp and have a low acid content. They are considered durable and permanent and are used for mounting prints, drawings and watercolors. Inferior grades of cardboard, such as corrugated board, are made from coarsely ground sulfite treated wood pulp. The grayish unbleached pulp is pressed into a thick sheet. Cardboard is moisture sensitive, may swell and buckle when wet, as well as emit organic acid volatiles. This type of cardboard is most often found in commercial shipping and packaging boxes. Because of these problems, many cardboard packaging materials are coated which makes recycling difficult.
Reinforced paper playing cards were first made in Frances in 1751, while the first cardboard box was produced in England in 1817. Corrugated cardboard was patented in 1871.
