The paper cards are folded vertically once and horizontally twice to wrap single or multiple packages of knitted socks, and then the paper cards are taped together. This process is called waist sealing. The knitted socks after waist sealing are then bagged. Therefore, the waist seal of knitted socks is an important part of knitted sock packaging and determines the quality of knitted sock packaging.
