Biodegradable Blown Film Extrusion
The process of Biodegradable Blown Film Extrusion utilizes materials such as PLA, PBAT, corn starch, calcium carbonate, and various other biodegradable compounds for the production of vest bags and trash bags. Its primary benefits include complete degradability and environmental sustainability. The die-head is designed with an internal 8-hole inflow feed structure, specifically optimized for the production of film using biodegradable materials like PLA and PBAT in blown film extrusion applications.
Plastic bags that are biodegradable can break down into carbon dioxide, water, methane, and other natural substances, thereby integrating into the carbon cycle over a defined timeframe and under specific environmental conditions.
