Hdpe Blown Film Machine uses and structural features
- Jan 28, 2019 -

HDPE blown film machine is mainly used for blowing high density polyethylene, low density polyethylene and linear low density polyethylene plastic film. At present, the machine has been widely used in the packaging of household and industrial products such as food, clothing, textiles and daily necessities. . The raw materials are formulated to produce a pearl film and a degradation film. This machine is the most widely used machine on the market and is the first choice for the blown film factory.


Generally, the main structural components of the HDPE blown film machine include: an extruder, a machine head, a die, a cooling device, a foam stabilization frame, a herringbone plate, a traction roller, and a winding device. In its structure, the screw and barrel parts are made of high-quality alloy steel, which is nitrided and precision machined. It has high hardness, strong corrosion resistance and durability.


The die of HDPE blown film machine is specially treated by hard chrome plating and adopts spiral mandrel structure design, which can make the melt material evenly extruded. The blown film has good surface finish, and the structure of air-cooling device is labyrinth type. Evenly. The winding device adopts pressure friction winding or center winding, and is adjusted by a torque motor, which is smooth in winding and convenient in changing rolls.
