Introduction: The Environmental Protection Wave Drives the Explosive Demand for Biodegradable Granulator Machines
Global plastic restriction policies are being implemented at an accelerated pace, making biodegradable film plastic granulator machines the fastest-growing segment in the plastic machinery industry. According to Global Info Research, the global biodegradable plastic market size is projected to exceed 20 billion USD by 2025, driving an annual growth rate of 12% in granulator machine demand. Chinese suppliers such as Zhuhai Keying and Nanjing Jiant have achieved breakthroughs in PLA/PBAT co-extrusion granulation technology, with equipment exports accounting for 28% of the market.
Core Technology Breakthroughs and Equipment Selection Guidelines
1. Processing Challenges and Solutions for Biodegradable Materials
- Twin-screw extrusion technology: Utilising a co-rotating design ensures uniform melting of materials like PLA/PHA, with biodegradation rates reaching 95%.
- Low-temperature control system: Precision PID temperature control modules maintain temperature differences within ±1℃, preventing thermal decomposition of heat-sensitive materials.
- Raw material compatibility: Supports co-extrusion granulation of six types of biodegradable resins, including PLA, starch-based materials, and PBAT.
2. Energy-saving and intelligent upgrades
- 30% energy savings: Integrated servo drive and heat recovery system, with power consumption per ton ≤280 kWh.
- Smart interlocking solution: Operates in tandem with the cast film extrusion production line (internal link) to achieve one-stop production from pellets to film.

Key Factors in Procurement Decisions and Risk Mitigation
1. Certification and Compliance Requirements
- EU EN 13432 and US ASTM D6400 certifications are mandatory qualifications for exports.
- An online quality inspection system must be installed to ensure melt index fluctuations ≤5%.
2. Long-Term Operational Cost Optimisation
- Select modular design equipment for easy upgrading to a cast film extrusion production line integrated unit.
- Prioritise suppliers with remote maintenance systems, with a response time of ≤4 hours for faults.
Future Trends and Industry Opportunities
- Policy-driven: China's 14th Five-Year Plan requires that biodegradable plastic production capacity account for 15% by 2025.
- Technology integration: AI vision inspection systems have improved particle defect detection accuracy to 99.3%.
- Emerging markets: Southeast Asia's demand for biodegradable films is growing at an annual rate exceeding 20%, driving a surge in particle machine exports.
