Advantages of ABA Multilayer Blown Film Machine
In some markets such as Türkiye, 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 costs. 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.
ABA multilayer blown film machine produces 30% stronger film
Two Extruders, Three Layers
The A-B-A multilayer blown film line 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 a larger percentage of CaCO3 with HDPE raw material. In-house recycled pellets can also be used for the mixture.
Enhanced Film Durability, 30% Stronger Than Monolayer Flim
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 the 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.
World-leading Multilayer Blown Film Machine Manufacturer
POLYSTAR, a Taiwanese manufacturer of blown film machines has shifted its main focus onto making and re-engineering ABA technology because it has noticed this big shift in market trend in many countries where it exports to. In Russia, for example, the mono-layer blown film market is almost dead for POLYSTAR, despite the fact that it used to sell at least 50 mono-layer blown film machines to the market annually for almost a decade. Instead, 90% of the blown film machines that POLYSTAR has sold to Russia since 2010 has been the ABA type. One of the leading and largest film and bag producers in St. Petersburg (Russia) currently with 60 sets of POLYSTAR's mono-layer blown film machines, has also been very active in upgrading their machines to the ABA type from mono-layer extruders.
