Product Description

Our company  research and development of super high speed film blowing machine, improved more suitable for raw material (secondary recycled materials) base on the Taiwan technology, screw segment compression, shear mixing advanced technology has applied for national patent, good shear and mixing the plastic is fully plastified, enhanced the thin film vertically and horizontally tension,as principle of the production increasing,  brightness and the feel of the film can meet the demand of bag market.
In some markets such as Turkey, Thailand and Vietnam where T-shirt bag production has become extremely competitive, film producers are now replacing their existing mono layer extruders with ABA 3 layer co extrusion blown film machines, mainly to save production cost. One of the biggest T-shirt bag producers in Vietnam has already replaced half of its mono layer extruders with ABA machines in the past 3 years to stay competitive in the local market.

The A-B-A blown film machine consists of two extruders, normally of two different sizes. The most common ones today are the combination of a 45mm screw diameter together with a 55mm for T-shirt bag production. For garbage bags, normally a 55mm screw diameter with a bigger 65mm is used. In the A-A outer layer, normally 20% of CaCO3 is used, with some additional of color masterbatch, LLDPE and a larger percentage of HDPE. The B layer can be used with larger percentage of CaCO3 with HDPE raw material. In-house recycled pellets can also be used to the mixture. 

Besides reducing a significant amount of raw material used in the formula, another advantage of the ABA machine is that the 3 layer film that it produces is 30% stronger than film produced by a mono layer extruder. The ABA machine is also much more economic comparing to an ABC three layer machine as it has one extruder less.

CHSJ-50/65 ABA Three Layers Co-extrusion FilmBlown Machine adopts special co-extrusion A+B+A film blowing die and has uniquefeatures in the production of HDPE, LDPE and LLDPE material. The physical strength of the film is enhancedthrough multiple-layer 

CHSJ-T ABA Three Layers Co-extrusion FilmBlown Machine adopts special co-extrusion A+B+A film blowing die and has uniquefeatures in the production of HDPE, LDPE and LLDPE material.
The physical strength of the film is enhancedthrough multiple-layer co-extrusion; the application of one host machine tosupply materials for inner and outer layers can reduce the configuration of theother host to cut cost, save energy and lower consumption.
Low pressure polyethylene (HDPE) and linearlow density polyethylene (LLDPE) are new varieties of polyethylene in theinternational market.
It has advantages of impact strength,penetration resistance, environmental stress crack resistance, and lowtemperature resistance, especially it can be used to make micro-thin films (the film strength of 0.015 mm film is as much as that of 0.03mm high-pressurepolyethylene film).
Because of its low cost, it is widely used inthe production of films. It can blow 3 kinds of polyethylene film including lowpressure, high pressure and linear low density film.
It can blow films with new materials as wellas reworked plastics with stable performance and reliable quality. This machineset applies a extruder with a special screw structure; advanced screw die head,flexible colling wind ring, and reasonable fixed iris structure can ensure agood proportion of 3 mixed polyethylene materials.
It is wrong to think that the three-layerco-extrusion machine will result in huge power consumption.
The three-layer co-extrusion machine onlyneeds two hosts: one is for the inner layer and the outer layer (A layer) andthe other is for the interlayer (B layer).
Reworked materials or other affordablematerials like 50% calcium carbonate can be used without affecting thestrength, weldability, printing properties of the products; and the coolingbecomes faster and the yield is higher because of the calcium carbonate or lowpressure polyethylene in the interlayer. 
Reduce the electricity consumption of each ton of film-the maximum energy saving can be 200 kwh/ton
Increase the efficiency of production per unit time.
Cut the raw material cost and improve the product quality. 
The cylinder and screw of this extruder are made of superior alloy steel through nitrogen treatment and precision finishing with the optimal hardness and corrosion resistance.
Scientifically designed, this kind of screw has many advantages like high production capacity and plasticization.
This machine set is used to blow low-density polyethylene (LDPE) and linear low density polyethylene (LLDPE) plastic film to produce various food and clothing packaging bags, garbage bags and vest bags for civil and industrial packaging uses.
