Machine Introduction
A monolayer blown film extrusion machine is a type of equipment used for the production of single-layer plastic films. The process begins with feeding Plastic granules into Hopper Loader and further granules extruded and melted with a continuous stream and pushed to die which shapes the melted plastic into a tubular form . The tubular film is inflated using compressed air , This process, known as bubble inflation or air cooling, stretches the film to the desired dimensions and cools it. The cooling process solidifies the molten plastic into a stable film .
Cygnet Manufactured Monolayer blown film machines can handle various types of plastic resins, including Low Density Polythene (LDPE), High Density Polythene (HDPE),Compostable (PLA –PBAT ) and others. The choice of resin depends on the desired properties of the film, such as transparency, strength, barrier characteristics, and heat resistance.
Cygnet Machinery Supplied Monolayer blown film machines are more affordable compared to multilayer machines. They are suitable for applications where the specific properties of a single-layer film are sufficient for packaging requirements, thus reducing production costs , designed for high-speed production, offering excellent output rates and productivity.

Major Components
- Extruder : Monolayer blown film machines is equipped with single extruder, responsible for melting and extruding a specific polymer. The extruder are equipped with Gravimetric Hopper loader, temperature control, melt pressure monitoring, and melt filtration systems to maintain optimal processing conditions for each material.
- Extrusion Die Design : A specially designed die which is a critical component of a Mono layer blown film machine. It is designed to shape the melted polymer streams into a single layer structure. The die is designed to ensure uniform layer with controlling bubble system. Cygnet Machinery offers both segments in Die a Rotating and Fix Spiral Type .
- Winding Systems : Advanced winding system provided equipped with automatic edge alignment systems and tension control mechanisms, are employed to improve winding quality and consistency. Cygnet machinery supplies Mono layer blown film machines with advanced control and PLC systems. These systems enable operators to set and adjust process parameters such as melt temperature, extrusion rates, layer thickness ratios, and air pressures. Real-time monitoring of parameters such as , bubble diameter, and cooling conditions allows for precise control and quality assurance.
