Product Description
Twin Head Blown Film Machine - Designed for HDPE and LDPE bag producers
Twin Head Blown Film Machine
  • Monolayer (1 Layer)
  • Two Die Heads, Single Screw
  • Film Width from 150~650mm
  • Extruder Dia: 45mm, 55mm, 75mm
  • Material: HDPE,LDPE
  • Output: 30~140 kg/hr
  • Works with virgin, recycled and CaCO3

POLYSTAR has installed more than 300 sets of its twin head blown film machines in many leading T-shirt bag makers' factory in many countries.

Normally when producing film rolls for T-shirt bag conversion which ranges from 300~700mm 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 offers an economic alternative and has a much faster return on investment comparing to a blown film machine installed with internal bubble cooling system (IBC). In the twin head blown film machines, 1 die head can reach much higher output with a bigger extruder (such as 65mm or 75mm in diameter) even when producing smaller width film. It is especially effective for T-shirt bag makers who are looking for machine with higher output but lower cost. 

Comparing to extruders with a single die head, the twin die extruders can achieve higher production capacity when producing film roll that are small in width, as the high extrusion output is dispersed into two separate channels of the die heads instead of one. 

Polystar designs and customizes this type of twin head blown film machine with different screw diameter and roller width depending on the customers’ requirement. Available in screw diameter of 55mm, 60mm, 65mm and 75mm and film width from 400mm up to 1000mm on each winder. The double head blown film machine 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. Polystar uses Siemens/ABB energy saving motors for the extruders which can reduce energy consumption up to 5%.

Polystar has installed more than 200 sets of the double-head blown film machine in Latin American in more than 15 countries throughout Central and South America.

Company Introduction
POLYSTAR’s twin (two) head blown film machine is very popular amongst bag producers of T-shirt, supermarket, flat, garbage and bottom-sealed bags (ranges from 200~600mm in width, in HDPE and LDPE). This high speed line provides a much faster return on investment comparing to a blown film machine equipped with IBC. In the double head blown film machines, one can reach much higher output even when producing at small film width. It is the perfect choice for bag makers who are looking for less expensive machines with higher output and good film quality.
