Description

Technical Field

[0001] The utility model relates to the technical field of sealing threads, in particular to an environment-friendly sealing thread. Background Technique

[0002] The principle of the sealing thread is to fasten the wrapped articles and containers to achieve sealing and prevent the influence of external factors on the articles.

[0003] At present, for the sealing thread on the market, during the packaging process, the wound sealing thread is wound around a winding roller to achieve the packaging of the sealing thread. When in use, the winding roller with the wound sealing thread is directly sleeved on the spool of the equipment. However, the existing winding roller for the sealing thread cannot rotate by itself during the process of winding and using the sealing thread. As a result, when using the sealing thread, it is necessary to rely on the pulling force of the sealing thread to drive the winding roller to rotate, which easily leads to the breakage of the sealing thread.

[0004] Therefore, we propose an environment-friendly sealing thread to solve the above-mentioned existing problems. Content of the Utility Model
