Three-to-Seven-layer co-extruding die head adopts the internationally advanced superposed die heads,of which each layer can heat and receive thermal insulation medium independently and insulate the heat effectively, which is good for blowing and making plastic film with difference temperature .The die head is of advanced construction and even arrangement of sprue-runner that can ensure the steady fluid and even thickness of film.

The traction system adopts+360°swing and uniform rotation in level direction to meet the requirements for high precision and high speed printing .The cooling system in IBC is an internationally  advanced technology today .The syetem adopts four ultrasonic wave probes to count the tested information,and at the same time,to guarantee the size of the film bubble steadily while replacing the  hot air in the film bubble through the contorl and regulation of in-out air output .It can increase the production output as well as its transparency and added value.

Computer control system.

USE:

Three-to-Seven-layer co-extruding upper traction rotation blown film machine until is developed and researched according to the market demands at the basis of domestic and foreign advanced technology .It is applied to packing with medium-high film .The film is of well barrier property ,retaining freshness,moisture-proof,frost prevention ,oxygen proof and oil-proof .So it can be widely applied to the light-weight packing,such as fresh fruits,meat,pickles,fresh milk,drink,medicine,etc.
