Yongbang designs blown film extrusion lines and automatic bag making machines for flexible packaging producers, supporting LDPE, HDPE, LLDPE, recycled and biodegradable materials.
Our blown film machines cover a full range of solutions from basic single-layer to three layer coextrusion, meeting various film production needs. It can blow produce LDPE, HDPE, LLDPE and other raw material films, suitable for scenarios such as food, clothing, industrial packaging, etc.
Double-Vent Air Ring
Ensures uniform cooling and consistent film thickness.
PLC Monitoring System
Real-time control of extrusion volume and thickness.
Multi-Layer Co-Extrusion
Produces composite films for enhanced performance.
We not only provide high-performance blown film machines, but also build a full industry chain solution from film production to bag making.
Our bag making machines provide a complete range of solutions from high-speed T-shirt bag production to precision flat-bottom and side-seal bag manufacturing. Designed to handle materials including LDPE, HDPE, and biodegradable PBAT, they meet the diverse needs of retail, food packaging, and industrial sectors.
Servo Motor Drive:
