Background technique

At present, plastic flat wire drawing units manufactured, sold and used at home and abroad generally use polypropylene resin (PP) or polyethylene (PE) as raw materials to manufacture flat wire, and then weave them into woven bags for packaging. The wire drawing unit cannot use other resins as raw materials to produce woven bags.

Now all walks of life and people's lives have a great demand for woven bags. Therefore, those skilled in the art are researching and exploring the use of other resins as raw materials to produce woven bags, one is to improve its performance, and the other is to reduce production costs. Examples include polyethylene terephthalate (PET) and other recycled plastics. The mechanical properties of PET are better than that of PE. If PET is used as raw material to make flat yarn into woven bags, the strength of the woven bag can be doubled. If recycled plastic is used as raw material to make flat yarn, a large amount of PET mineral water bottle waste can be recycled. As raw materials, flat yarn is used to produce woven bag packaging items, which greatly saves the cost of raw materials, achieves waste recycling and reuse, reduces production costs, and reduces the impact of plastic waste on the environment.

However, these resins are difficult to process in wire drawing, so there is no production equipment capable of processing these resins.
