RG-C series high and low pressure film blowing machine
RG-C series high and low pressure film blowing machine


High and low pressure film blowing machine is suitable for high density polyethylene (HDPE), low density polyethylene (LDPE) and linear low density polyethylene (LLDPE) plastic film, widely used in food, clothing, textiles, daily necessities and other public goods and industrial goods packaging. The raw material can produce pearlescent film and degradable film through prescription. The machine is the most widely used equipment in the market and is the first choice for the blowing film factory.


1. screw and barrel are made of 38CRMOAL alloy steel. They are treated by nitriding and precision machining. They are of high hardness, corrosion resistance and durability.

2. die hard chromium plating, the structure of the spiral mandrel, extrusion of uniform melt, blown film is good finish, air-cooled device structure for the maze, the wind evenly.

3. roll take device adopts pressure friction winding or central take-up, adopt torque motor adjustment, winding up flat, easy to change volume.

Usage method:

Check the temperature controlled condition, heating appliances in good condition, pay attention to adjust the heating temperature in the index range in time.

Check the traction speed control film thickness

3 to observe and adjust the film thickness uniformity, folding size standard.

The inspection of the air storage cylinder pressure is not too high, but due to standby pressure.

The check and control the ratio of raw materials mixed evenly.

The inspection of raw materials has no impurities, especially should check with the iron magnet.

But check the gear box and the air compressor cylinder lubricating oil lubrication.

The regular inspection of the operating temperature of the motor and mechanical transmission.
