Many factories face unstable film quality and rising production costs, which ultimately delay delivery schedules. A high-performance blown film machine is an effective solution to these challenges.
Blown film machines vary greatly in speed, material adaptability, and film stability. Chaoxin offers HDPE/LDPE/LLDPE high-speed and ultra-high-speed models with outstanding energy efficiency, durability, and operational stability. Understanding each machine’s strengths and limitations helps you select the ideal model for packaging, agricultural, or industrial film production.
Blown film machines are the core equipment for plastic film production and are widely used in food packaging, agricultural cover films, retail bags, and industrial packaging. As the market demands thinner, stronger, and higher-quality films, choosing the right machine becomes essential for improving stability, reducing energy consumption, and achieving long-term cost efficiency. Zhejiang Chaoxin Machinery Technology Co., Ltd. provides complete solutions—from standard blown film machines to advanced ultra-high-speed models—supported by precision manufacturing, strict quality control, and internationally certified components to ensure durability and high performance.
Chaoxin Blown Film Machine
Chaoxin blown film machines support HDPE/LDPE/LLDPE film production and serve as the primary equipment for general packaging applications.
Key advantages include:
Equipped with GE, Siemens, and Brook motors for strong torque and stable speed.
Energy-saving system that significantly reduces energy consumption per kilogram of film.
Three-year warranty on core components, supporting long-term high-load operation.
International-brand electrical components such as ABB, Omron, and Schneider for enhanced stability and durability.
Self-developed bimetallic screws (30:1 & 32:1) designed for higher plasticizing efficiency, greater output, and superior film stability.
Optimized air ring, precision die head, and efficient cooling structure, enabling consistent production of micron-level films.
Patented five-roller traction system, which enhances film flatness and ensures tidy and stable winding.
Improved die-flow design ensures uniform film thickness—ideal for packaging film, T-shirt bags, garbage bags, protective films, agricultural films, and more.
How to Choose the Right Blown Film Machine for Your Business
Selecting the right blown film machine requires evaluating production goals, materials, application scenarios, film performance, and investment budget.
1. Production Capacity Requirements
Ultra-high output: Choose Chaoxin high-speed or ultra-high-speed blown film machines.
2. Film Application
Different end uses require different machine configurations:
Shrink film
Agricultural film
Courier/express bags
Liquid packaging bags
Industrial packaging bags
T-shirt bags
Garbage bags
Biodegradable films and bags
3. Material Compatibility
For recycled or mixed materials: Choose multi-layer co-extrusion technology for better stability.
For 100% virgin raw materials: High-speed and ultra-high-speed machines achieve maximum efficiency.
