Characteristics of Blown Film Unit Industry in Dalian

Features of Blown Film Unit Industry in Dalian

As a core city in Northeast China’s old industrial base, Dalian boasts a long-established and solid equipment manufacturing industry. As an important category of plastic processing machinery, blown film units occupy a pivotal position in Dalian’s industrial layout. Supported by technical expertise, geographical advantages and favorable policies, the local industry has formed distinct characteristics and become a key player in China’s blown film equipment sector.

 1. Solid Industrial Foundation & Rich Technical Experience

Dalian’s machinery manufacturing dates back to the early days of the People’s Republic of China, with abundant experience accumulated in precision machining, hydraulic transmission and automatic control.

Backed by such strengths, the local blown film unit industry has grown steadily. Core components including screws and dies reach leading domestic machining precision. Local manufacturers are capable of producing large-scale units with a width over 10 meters to meet demands for professional packaging films. Their equipment features outstanding stability, with service life over 20% longer than the industry average.

Since the 1990s, renowned local machinery enterprises have focused on R&D of blown film equipment. Their self-developed three-layer co-extrusion blown film units meet international standards in terms of film thickness uniformity and tensile strength.

2. Specialized Product Upgrade Focused on High-value Fields

Against rising market requirements for packaging materials, local manufacturers have shifted from low-end general-purpose equipment to professional dedicated units.

- **Pharmaceutical & Food Industry**: Sterile blown film units equipped with online detection systems are developed for clean production, suitable for producing PVDC fresh-keeping films and EVOH barrier films.

- **Eco-friendly Sector**: Units applicable to biodegradable materials such as PLA and PBAT are developed to solve processing difficulties, gaining growing domestic market share.

- **Specialized Packaging**: Low-temperature resistant high-barrier blown film units are launched for e-commerce cold chain packaging to ensure fresh food preservation during transportation.

 3. Industry-university-research Cooperation Accelerates Technical Upgrading

Dalian University of Technology, Dalian Polytechnic University and other research institutions provide strong technical support. Enterprises jointly build R&D centers with universities to tackle core technologies.

The electromagnetic induction heating system co-developed by local firms and Dalian University of Technology replaces traditional resistance heating, cutting energy consumption by over 25% and obtaining national patents.

With IoT technology applied, the equipment realizes remote monitoring, automatic parameter adjustment and fault early warning, raising production efficiency by 15% and reducing defective product rate by 10%.

4. Prominent Global Layout Supported by Port Advantages

As a major northern port city, Dalian enjoys convenient import and export conditions, driving steady growth in blown film unit exports.

Products are exported to Northeast Asia, Southeast Asia, the Middle East and part of European markets. High-precision and stable local blown film units have become designated supplies for many packaging enterprises in South Korea.

Enterprises participate in international exhibitions such as K Show and China International Plastics Exhibition to boost global brand influence and expand overseas market share steadily.

5. Complete Industrial Chain with Obvious Cluster Effect

A full-fledged industrial chain for blown film units has taken shape in Dalian and surrounding areas.

Local suppliers provide professional molds, motors and integrated control systems, enabling quick response to customized demands and shorter equipment delivery cycles.

Plastic processing industrial clusters in nearby Yingkou and Panjin offer vast application markets, forming a sound closed loop covering equipment R&D, production and application.

 6. Policy Incentives Boost Green Industrial Transformation

Northeast revitalization strategies and environmental policies fuel industrial development.

Governmental subsidies for technical renovation and R&D funds encourage enterprises to upgrade equipment.

In response to plastic restriction policies, enterprises accelerate the R&D of processing equipment for degradable materials to seize market opportunities.

Energy-saving blown film units are entitled to tax preferences, promoting the industry toward low energy consumption and low carbon emission.

 Conclusion

Thanks to solid industrial foundation, targeted product positioning, collaborative innovation mechanism, global layout and complete supporting chain, Dalian’s blown film unit industry has formed unique competitive edges. Driven by intelligent and green development trends, the industry will keep upgrading and underpin the high-quality development of China’s plastic processing industry.
