Film Blowing Machine
Introduction
A Film Blowing Machine is industrial equipment used to convert plastic resin (such as HDPE, LDPE, LLDPE, or PP) into continuous plastic film rolls through extrusion and air inflation.
The final film is widely used for plastic bags, packaging materials, food packaging, industrial wrapping, and agricultural films.

Machine Types
Single Layer Film Blowing Machine
A single-extruder machine designed to produce basic plastic film with stable thickness for general packaging applications at the lowest investment cost.
Double Layer Co-Extrusion Machine
A two-extruder system that combines different materials to produce stronger film with improved barrier performance and higher durability.
ABA Film Blowing Machine
A three-extruder co-extrusion machine (A-B-A structure) that uses recycled material in the core layer to significantly reduce raw material cost while maintaining high surface quality.
High-Speed Film Blowing Machine
An upgraded industrial system equipped with high-efficiency cooling and traction units to achieve continuous high-output production with stable film quality.
Applications
Plastic Bag Production
Manufacturing shopping bags, garbage bags, and retail bags in large quantities.
Food Packaging
Produces film for frozen food and fresh produce with stable sealing performance.
Industrial Packaging
Used for pallet wrapping, machinery protection, and export cargo packaging.
E-commerce & Logistics
Widely used for courier bags, mailing bags, and shipping protection films.
Agriculture Film
Produces greenhouse and mulch film for moisture retention and crop protection.
Buying Guide
When selecting a film blowing machine, key factors include:
- ✓ Production capacity (small / medium / large scale)
- ✓ Film width requirement (up to 2000mm+)
- ✓ Material type (LDPE, HDPE, LLDPE, PP)
- ✓ Layer structure (single, ABA, multi-layer)
- ✓ Automation level (manual / semi / fully automatic)
