Roll packaging is a container made by winding semi-finished products or products from various processes in textile and chemical fiber production. For example, tube yarn, bobbin, hank yarn, silk cake, warp beam, etc. The roll pack with increased capacity is called "large roll pack".

The tubes, strips, shafts, etc. used for winding products are called "packaging containers". Twisted yarn refers to a small circular tool with a diameter of about 50cm that is used to shape the yarn.
