ABA Three Layer Co-extrusion Machine
Multilayer co-extrusion designed for the flexible packaging industry
The A-B-A multilayer blown film line consists of two extruders, normally of two different sizes. 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 a larger percentage of CaCO3 with HDPE raw material. In-house recycled pellets can also be used for the mixture.
With the ABA structure, the final film rolls are stronger than monolayer blown films, which means that it would be more suitable to be produced into shopping bags for its higher tear resistance.
