PLASTAR launches advanced five-layer co-extrusion blown film production line

PLASTAR has launched a new generation of five-layer co-extrusion blown film production lines, aiming to support packaging manufacturers with higher production efficiency, better material utilization and significantly reduced energy consumption.

 

The line's five-layer co-extrusion architecture supports flexible material formulations – combining virgin resin with recycled content or producing functional barrier layers while maintaining film strength, barrier properties and optical performance.

 

This modular structure directly supports the industry's transition to circular packaging systems and helps manufacturers keep up with changing regulatory requirements.

 

Fully automatic air ring technology

 

A key feature of the system is PLASTAR's fully automatic air ring technology. This technology integrates 120 independently controlled air volume adjustment units, which can accurately and real-time adjust the air flow distribution around the film bubble.

 

The result is a film thickness tolerance of ±3‰, a scrap rate reduction of more than 3%, and quantifiable improvements in overall material efficiency and production consistency.

 

Unlike traditional blown film systems that usually rely on semi-automatic cooling control in a limited area, PLASTAR's intelligent air ring greatly improves process stability while reducing reliance on manual operations.

 

Traditional systems often face the problem of inconsistent bubble stability and require frequent manual adjustments; in contrast, PLASTAR's solution provides continuous closed-loop control, lower energy consumption, and higher production repeatability.

 

Complementing this design is a dual-motor edge-tracking automatic wind ring – a patented dual-motor edge-tracking wind ring system, which further reduces mechanical complexity and power consumption.
