| Producing Packaging Bag Three Layer ABA 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 Packaging Bag Three Layer ABA Blown Film Machine, 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 Packaging Bag Three Layer ABA Blown Film Machine the past 3 years to stay competitive in the local market. The Packaging Bag Three Layer ABA 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 amount of raw material, another advantage of Packaging Bag Three Layer ABA Blown Film Machine is that the produced 3 layer film is 30% stronger than mono layer. The Packaging Bag Three Layer ABA Blown Film Machine is also more economic comparing to an ABC layer machine as it has one extruder less. POLYSTAR, a Taiwanese manufacturer of Packaging Bag Three Layer ABA Blown Film Machine 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. |  |

| Packaging Bag Three Layer ABA Blown Film Machine Technology: Thinner, stronger film at lower production cost | |
 | The Packaging Bag Three Layer ABA Blown Film Machine 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. |

| In June, the film producer located in Mashhad, Iran has added the 4th POLYSTAR line for the production of garbage and T-shirt bags. Numerous film and bag producers have acquired the ABA blown film technology in recent years as a replacement of monolayer machines for bag production, largely because a high percentage (up to 50~70%) of CaCO3 compounds can be used in the B (middle) layer of the film, while the inner and outer (A-A) layers can be filled with virgin material to maintain good quality of the film surface. This significantly cuts down the usage of virgin raw material and thus reduces production cost. The popular usage of Packaging Bag Three Layer ABA Blown Film Machine for T-shirt and general packaging bag production has first started in Turkey in 2005, and has seen significant growth in the neighboring Russian market (in which POLYSTAR now holds over 50% of the market share for ABA) since 2011 and now in Iran as well in this region. POLYSTAR will install 3 more ABA machines in Iran this August along with other projects under production. As the cost of raw material fluctuates frequently, the ABA machines add great advantage and flexibility (comparing to mono layer, single extruders) for the bag producers – with the option of using high % CaCO3 compounds or recycled material in the middle layer. The Packaging Bag Three Layer ABA Blown Film Machine consists of two extruders to produce 3-layer film. The most common ones today are the combination of a 45mm extruder together with a 55mm to produce 500~1000mm film width, and a 55/65mm extruder combination to produce 1100 up to 1400mm film in width, particularly for the production of T-shirt bag and garbage bags. The B (middle) layer, which makes up about 60~75% of the film composition, usually consists of 60~70% CaCO3 compounds. Recycled pellets (from in-house waste) can also be added to the blend. The re-designed screw helps to achieve maximum efficiency during the film production process. A better extrusion mixing is able to produce outstanding film quality, even when working with 40~70% CaCO3 and recycled material in the mixture. A main focus for POLYSTAR: Packaging Bag Three Layer ABA Blown Film Machine POLYSTAR has put a major emphasis on the re-designing and manufacturing of ABA blown film extruders in recent years. As of June 2016, 135 sets of POLYSTAR Packaging Bag Three Layer ABA Blown Film Machine have been installed worldwide, particularly in countries where monolayer film production has become competitive. POLYSTAR provides high customization on the Packaging Bag Three Layer ABA Blown Film Machine depending on customer’s requirement, space and budget concerns. The main advantages of the Packaging Bag Three Layer ABA Blown Film Machine are:
