Biodegradable Blown Film Extrusion

Blown Film Extrusion

Blown Film Extrusion is a process that employs materials such as PLA, PBAT, corn starch, calcium carbonate, and other biodegradable substances to manufacture vest bags and trash bags. This method offers significant advantages, including complete degradability and environmental sustainability. The die-head features an internal 8-hole inflow feed design, specifically optimized for processing biodegradable materials like PLA and PBAT in blown film extrusion applications.

Blown Film Extrusion technologies are rapidly evolving, providing new solutions for sustainable packaging.

Biodegradable plastic bags are capable of decomposing into carbon dioxide, water, methane, and other natural compounds, thereby reintegrating into the carbon cycle within a specified timeframe and under particular environmental conditions.

This makes Blown Film Extrusion a crucial part of modern ecological initiatives.
