The history of cardboard cores and cardboard tubes as a form of packaging is closely linked to the development of paper manufacturing since cardboard, or paperboard, can be regarded simply as a form of thick paper. According to tradition, the first paper was first made in 105 AD by Ts'ai Lun a servant of the Chinese emperor Ho Ti.  The earliest record describes how he "made paper by pulping fishing nets and rags. Later, he used the the fibres of plants which were boiled and made into a mash. They were  then stirred into a pulp and spread on a frame. When it had formed a thin tissue, it was pressed with heavy weights to make paper.
Hope I helped.
