工作原理：挤出吹膜是指在一定温度，一定剪切力的作用下使塑胶熔体连续的通过口模被挤出,由压缩空气吹胀，风环冷却和变频牵引而获得的双折塑胶薄膜的工艺过程。
Working principle: Under certain temperature and certain shear force, the plastic melt is continuously extruded through the die, and is blown by the compressed air, the air ring cooling and the frequency conversion traction. Then Obtained bifocal plastic film process.
