Rotary Die Head Blown Film Line
The rotary die head blown film line mainly works to blow a variety of plastic laminated films made of LDPE, HDPE as well as LLDPE. These PE films are widely employed as raw materials to make packaging bags for liquid, printing substrate, export product, industrial product, and so on.
The barrel and screw of the extruder adopted by the PE film blowing machine are both manufactured from 38CRMOAIA alloy steel with optimum hardness and durability due to the nitrogen treatment and precision finishing. The auxiliary equipment of the blown film line is equipped with platform type working table, making operation more convenient. In addition, it is also equipped with the forming ring. The winding part of the blown film line is characterized by double film winding as well as double cutting blades. The winding operation is driven by the torque motor, thus ensuring appropriate tension, neat roll winding and easy roll changing.
