Brochure
A Blown Film Machine is an advanced plastic extrusion system designed to manufacture thin plastic films through the blown film extrusion process. It is widely used in the packaging and flexible film industry to produce high-quality polyethylene films in tubular form, which can be slit or sealed depending on application requirements.
The machine converts thermoplastic raw materials—typically polyethylene resins—into continuous film by melting, extruding, inflating, cooling, and winding the material into rolls. Blown film technology is preferred for its versatility, excellent mechanical strength, uniform thickness distribution, and cost-effective production capabilities.
Two Layer & Three Layer Film Plant
Mono Layer Blown Film Machine

FAQs – Two Layer & Three Layer Film Plant
What is a Blown Film Machine?
A Blown Film Machine is an extrusion system used to manufacture plastic films by melting polymer resin and inflating it into a thin tubular bubble, which is then cooled and wound into rolls.
What materials can be processed in a Blown Film Machine?
Common materials include:
- LDPE (Low-Density Polyethylene)
- LLDPE (Linear Low-Density Polyethylene)
- HDPE (High-Density Polyethylene)
- HM-HDPE
Reprocessed / Recycled materials (depending on configuration)
What is the difference between Mono, 2-Layer, and 3-Layer machines?
- Mono Layer: Single material layer, suitable for basic packaging.
- 2-Layer (A+B): Improved strength and sealing properties.
- 3-Layer (A+B+A / A+B+C): Better mechanical strength, durability, and performance for advanced packaging.
What is the typical film thickness range?
Most blown film machines produce films between 20 to 200 microns, depending on die size, material, and machine configuration.
