Characteristics of plastic woven bags

Plastic flat wire, which is the basic material for producing plastic woven fabric. The flat yarn is melt-extruded into a film from a specific variety of polypropylene and polyethylene resin, and then cut into strips longitudinally, and the strips are simultaneously heated and drawn. After final setting, it is finally wound into a flat yarn ingot for weaving the braid.
The flat yarn process, also known as the yarn making process, is the first process of plastic braid production and the most important process.
The flat yarn production process is divided into two types according to the film formation method. The tube film and the film are divided according to the cooling method after film formation, air cooling, water cooling and intercooling. According to the drawing heating method, there are hot plates, hot rolls, hot air, press The spindle winding is divided into a group, a concentrated cycloid winding, a single spindle winding, and a magnetic torque winding.
