Three-to-Seven-Layer Co-extruding Traction

■Three-to-Seven-layer co-extruding die head adopts the interna-tionally advanced superposed die heads, of which each layer can heat and receive thermal insulation medium independently and can insulate the heat effectively, which is goog 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 isand internationally advanced technology today, The system 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 tot air in the film bubble through the control and regulation of in-out air output. It can increase the production output as well as its transparency and added value.
■Computer control system.

■Three-to-Seven-layer co-extruding upper traction rotation blown film machine unit is developed and researched according to the marketdemands 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.

OPTIONAL EQUIPMENT:
1.AUTO AIR RING(AUTO ADJUST THE THICKNESS OF FILM)
2.IBC FILM BUBBLE INNER COOLING SYSTEM
3.AUTO MEASURE THE THICKNESS OF FILM ON LINE 
4.COMPUTER CONTROL SYSTEM、
