paper cups Manufacture[2016-03-01]


The base paper for paper cups are called "cup board" and are made on special multi ply paper machines and have a barrier coating for waterproofing. The paper needs high stiffness and strong wet sizing. The cup board grades have a special design for the cup manufacturing processes. The mouth roll forming process requires good elongation properties of the board and the plastic coating. A well formed mouth roll provides good stiffness and handling properties in the cup. The basis weights of the cup boards are 170–350 g/m2.

To meet hygiene requirements, paper cups are generally manufactured from virgin (non-recycled) materials.[citation needed] The one exception to this rule is when the paper cup features an extra insulating layer for heat retention, which never comes into contact with the beverage, such as a corrugated layer wrapped round a single-wall cup.
