Product Configuration

1. High capacity and lower energy consumption: One extruder drives two die heads, producing nearly as much as two single machines with the same screw specifications. The motor, heating, and gearbox of the main machine are shared, spreading out energy use, so the electricity consumption per kilogram of film is noticeably lower than with two separate blowers, making it really energy-efficient.
2. Saves labor and factory space. You only need one operator to monitor two film bubble lines, cutting labor costs in half compared to two separate machines. The integrated layout takes up less workshop space, making it perfect for bag processing factories with limited space.
3.Flexible production, can handle multiple specifications with the same material. Under the premise of using the same raw material, the two die heads can be configured with different die sizes, allowing the production of two different film widths at the same time (for example, one making 25cm vest bags film, the other making 40cm flat bags film); or both lines can produce the same specification for large-scale production, adapting to order combinations.

What is a single screw double die head film blowing machine?
It is a mono-layer blown film machine that uses one extruder to feed two die heads at the same time. This allows bag makers to produce two film tubes or two film widths in one production run, instead of running two separate machines.
How does one extruder drive two die heads?
The single screw plasticizes and meters the material, and the melt is split to supply both die heads. The machine is designed for stable output to each die head, so both films can be produced simultaneously from the same material recipe.
What are the main benefits compared with a single die head machine?
The double die head design helps cut labor and energy costs per kilogram of film, produces two film widths at once, and reduces the floor space needed compared with installing two separate lines. It is a practical choice for bag makers who want higher output without doubling machine count.
What materials and film products can it produce?
As a mono-layer blown film machine, it is suitable for common polyolefin film production such as LDPE, LLDPE, and HDPE bags and packaging films. The exact material and product mix depends on the screw design and die head configuration selected for your application.
