Normally when producing film rolls for nylon bag conversion which ranges from 6"~15"(INCH) in width, it is difficult to achieve higher output by using a bigger extruder for such small film width unless the blown film extruder is equipped with an internal bubble cooling. The Twin head blown film machine for nylon bag offers an economic alternative and has a much faster return on investment comparing to an extrusion making machine installed with IBC system (Optional). In Twin head blown film machines for nylon bags, one die head can reach much higher output with a bigger Extrusion when producing smaller width film, especially effective for nylon bag makers who are looking for a machine with higher output but lower cost. Compared to extruders with single die head, the Twin head blown film machine for nylon bags can achieve higher production capacity when producing film roll that is small in width, as the high extrusion output is dispersed into two separate channels of the die heads instead of one. DIPO designs and customizes this Twin head blown film machine for nylon bags with different screw diameters and roller width, depending on the customers’ requirement. The Twin head blown film machine for T shirt bag also allows producers to switch between HDPE and LDPE production as well as producing different film width on the same machine on each winder simultaneously. A special screw design is used to provide good mixing and stable output for both HDPE and LDPE material. Bimetallic treatment is applied to process a higher percentage of recycled material and CaCO3 compound. DIPO uses Siemens/ABB energy saving motors for the Twin head blown film machine for T shirt bags, reducing energy consumption by up to 5%.
