This film blowing machine is very suitable for running LDPE materials, it can improve the film strength and quality. If we use air chiller with blower, it will cool the film bubble faster and improve the transparency more.
● There is gusset and embossing roller on traction. So it can do shopping bag film rolls also. The gusset parts is designed from Taiwan. It is very easily to operate.
● The double rewinder is controlled by inverter, and there are 5 pcs cutting knife. So it can run back to back rolls.
● For the film blowing machine blower, we use inverter control. So it can make machine more quietly and accurate.
