Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a tube cloth cutting device for plastic woven bags. Background Art

[0002] Woven bags, also known as snakeskin bags, are a type of plastic bag used for packaging. Their raw materials are generally polyethylene, polypropylene and other chemical plastic raw materials. Woven bags are mainly made of polypropylene as the main raw material, which is extruded and stretched into flat yarns, and then woven, knitted and made into bags. The main raw material produced abroad is polyethylene. Woven bags have a wide range of uses, mainly used for the packaging and packaging of various items, and are widely used in industry.
