2025-05-15 17:52
In 2025, the global packaging industry is accelerating its transition to energy saving, and power saving stretch film machines have become the core equipment for cost reduction and efficiency in the manufacturing industry by virtue of intelligent frequency conversion technology and heat recovery system. According to international market data, the proportion of electric energy consumption in the procurement cost of this equipment is as high as 42%, and Chinese manufacturers have improved the comprehensive energy efficiency to an industry-leading level by integrating servo drive modules.
Power-saving stretch film machine core technology breakthroughs
Three energy-saving modules work
- Frequency conversion servo drive system: dynamically adjust the motor speed to match the production load, reducing idling energy consumption by 18%-25%
- Film Thickness Adaptive Algorithm: Adjust the tension in real time by laser thickness gauge, reduce the breakage loss of ultra-film below 12μm
- Waste Heat Recycling Device: Recover the braking energy for the raw material preheating, shorten the start-up time by more than 30%.

Global Market Landscape and Key Technology Streams
Analysis of Taiwan's Technology Advantages
Taiwan manufacturers such as TW Packaging have developed low-friction guide roller technology, which enables PE film production speed to be increased to 350m/min, while maintaining ±0.8% tension stability. Its equipment is adapted to the characteristics of highly elastic film materials, which differentiates it from the generic designs of China stretch film machine manufacturers.
Innovative Supply Chain Practices in China
- Raw Material Pre-treatment System: Integrated online inspection module for plastic pelletizer ensures that the moisture content of granules is ≤0.3%, reducing energy consumption in the rewinding process
- Intelligent O&M Network Remote diagnostic service: Mainstream manufacturers provide remote diagnostic service, with fault response time compressed to less than 2 hours.
Six Evaluation Dimensions for Purchasing Decision
Verification of Energy Efficiency Certification System
- Verification of EU ERP Lot9 or US Energy Star certification labels
- Require suppliers to provide energy consumption test reports under full/no load conditions
Equipment linkage compatibility test
- Verify data interaction protocol with stretch film rewinder
- Ensure support for OPC UA or Modbus industrial communication standards
Full Life Cycle Cost Measurement
