ABA Co-extrusion blown film machine has its advantages over one layer blown film machine for certain applications like garbage bags, shopping bags, and T-Bags that are higher in thickness or require more film strength. In markets such as Australia and the UK, producing larger-sized garbage bags with ABA co-extrusion lines has become the industrial standard.

Benefits of ABA co-extrusion blown film machines:

• Cost-saving: virgin material is applied mainly on the outer (thin) layers which is relatively a small percentage of the film composition. These thin layers can cover the middle layer well enough for a shiny film surface and good sealing

• Stronger: higher resistance compared to single-layer films of the same thickness.

• Better material mixing: produce better quality film, especially when using recycled pellets. The same result as ABC.

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 color masterbatch, LLDPE, and a larger percentage of HDPE. The B layer can be used with a larger percentage of CaCO3 with HDPE raw material. In-house recycled pellets can also be used in 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 economical compared to an ABC three layer machine as it has one extruder less.
