Global environmental awareness has prompted the manufacturing industry to transition towards green production. The need for "carbon reduction" in the CFV stages has led the global blown film manufacturing industry to pursue sustainable development solutions. Chyi Yang's 5-layer / 7-layer co-extrusion blown film machines have become a key player in today's green supply chain due to their three key advantages: "Big Data Analysis," "Precision Formulation and Calculation Functions," and "Recycled Waste Technology Innovations" in their multi-layer blown film machines. The international blown film manufacturing market also recognizes the indispensability of Chyi Yang in the trend of carbon reduction.
