[0002] Pearl cotton is a soft and elastic material. Bags made from it can protect the contents and are widely used for packaging mobile phones, instruments, meters, hardware lighting, and handicrafts. Pearl cotton packaging bags are made by melting and cutting double layers of pearl cotton using a bag-making machine. This involves using a high-temperature cutter to simultaneously cut and weld.
