Three Layer Film Blowing Machine

Three Layer FilmBlowing Machine

LPDE film has advantages ofexcellent transparency and great heat sealing ability, but poor heat-resistantability is its disadvantage. LLDPE has advantages of strong toughness andexcellent cold-resistant ability, but its transparency is not good. HDPE filmhas advantages of excellent heat-resistant ability and strong mechanicalproperty, but its transparency is not good either. So it will be ideal if thereis a kind of film which has all the advantages mentioned above. Actually our three layer filmblowing machine can produce this kind of multi-function plastic film which hasadvantages of excellent transparency, heat-resistant and cold-resistant abilityas well as strong mechanical property by blowing LDPE, HDPE and LLDPE materialsand extruding them together.

Highefficient and energy-saving extruders are installed to improve productionefficiency and reduce production cost. Advanced IBC bubble inner cooling systemis also installed to produce excellent transparency and better physicalproperty plastic film. Compared with other film blowing machines, it is moreconvenient to maintain three layer film blowing machine and our machine canprevent leaking materials. Repeated horizontal swing rotation of tractionmachine takes place of rotation of die, and die structure is simplified. Thenmaterial leakage caused by the rotation of die, difficulty of sealing andmaintenance are avoided. And the problem of unequal dimension of film issolved, thus ensuring excellent flatness.

Besides,high precision bending radius control system can regulate air flow rate bycontrolling fan speed, and small bending radius error can be acquired. Highprecision mold and high efficiency wind cooling system can ensure that filmthickness is uniform and machine production efficiency is high. And three layerfilm blowing machine is widely used to produce compound film basement, film forholding liquid, shrink film, protective film, cable film, polymer adhesivefilm, multi-function wrapping film and other film, and can meet therequirements of high precision and high speed color printing, compound andpainting products.
