[0002] PE packaging bags are plastic packaging bags made of polyethylene. Polyethylene, referred to as PE, is a thermoplastic resin made by polymerization of ethylene, usually in the form of transparent plastic bags. PE bags are widely used in the packaging of clothing, bags, electronic products and other commodities because of their odorless, non-toxic and plastic-like properties. When PE packaging bags are produced, they will be cut after production to make their size fit the size of the packaged product.

[0003] When cutting PE packaging bags, in order to improve the cutting efficiency, the PE packaging bags are generally placed on a conveyor belt and cut while being transported. However, after the cutting is completed, due to the small weight of the PE packaging bags, it is easy for them to fall off the conveyor belt during transportation, causing pollution or damage.
