ABA blown film machine

Producing T-shirt bags with 3 layer blown film machine 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 ABA 3 layer 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.
