Iran – LDPE/HDPE T-shirt bag 3 layer blown film machine a new trend for bag makers
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 LDPE/HDPE T-shirt bag 3 layer 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 LDPE/HDPE T-shirt bag 3 layer blown film machine in Iran this August along with other projects under production. As the cost of raw material fluctuates frequently, the LDPE/HDPE T-shirt bag 3 layer blown film machine 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.
In markets where the price of HDPE raw material has increased significantly, LDPE/HDPE T-shirt bag 3 layer blown film machine provides a great advantage in terms of lowering production cost and increasing product quality and competitiveness, especially for 15 ~ 30 micron in HDPE. Virgin material is applied mainly on the A-A (inner and outer) layers, which are relatively a very small percentage of the film composition with the ratio of approximate 1:6:1 (inner: middle: outer)
Besides a standard and economic, simple ABA model, POLYSTAR also offers more advanced optional upgrades such as precise gravimetric dosing system, extrusion control and fully automatic cutting and winding to enhance the performance and quality of the film production.
