Stronger, higher film resistance: Comparing to mono layer film products with the same thickness
Cost saving: Virgin material is applied mainly on the outer (thin) layers which is relatively a very small percentage of the film composition
Better material mixing: With co-extrusion to produce better quality film
Main Usage & Applicationof Garbage Bag ABA Blown Film Extruder
For the production of T-shirt bags, garbage bags and shrink film (for bottle wrapping)
60% CaCO3 compounds or recycled material can be used in the middle layer
Thin outer layers with virgin material to cover the film surface so that it still looks good and shinny despite the usage of secondary grade material in the middle layer

Producing T-shirt bags with Garbage Bag ABA Blown Film Extruder significantly reduces cost
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 Garbage Bag ABA Blown Film Extruder, mainly to save production cost. One of the biggest T-shirt bag producers in Vietnam has already replaced half of its mono layer machine with Garbage Bag ABA Blown Film Extruder in the past 3 years to stay competitive in the local market.
The Garbage Bag ABA Blown Film Extruder 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 amount of raw material, another advantage of Garbage Bag ABA Blown Film Extruder is that the produced 3 layer film is 30% stronger than mono layer. The Garbage Bag ABA Blown Film Extruder is also more economic comparing to an ABC layer machine as it has one extruder less.
POLYSTAR, a Taiwanese manufacturer of Garbage Bag ABA Blown Film Extruder has shifted its main focus onto re-engineering ABA technology because it has noticed this big shift in market trend in many countries where it exports to.
POLYSTAR has recently installed 22 sets of mono layer machines in Yangon, Myanmar in a newly-established film production factory. However, this type of set up is only in where labor cost is still low. In markets where labor cost is higher and more competitions exist, producers must find a way to lower their production cost to increase profit margin.
Garbage Bag ABA Blown Film Extruder Technology: Thinner, stronger film at lower production cost
The Garbage Bag ABA Blown Film Extruder offers more flexibility on film formula. The three layer film is 30% stronger than mono layer film, and production cost can be saved up to 50%. Based on the unique screw design, up to 60% CaCo3 can be added to machine with excellent mixing effect.
By using the gravimetric 4 components dosing unit, operator is capable to control the accuracy of formula when mixing main material resins (either virgin or recycled) together with additives, fillers, and masterbatches.
