Blown film extrusion is one of the most significant polymer processing methods. Several billion pounds of polymer, mostly polyethylene, are processed annually by this technique. While some applications for blown film are quite complex, such as scientific balloons, the majority of products manufactured on blown film equipment are used in commodity applications with low profit margins: grocery sacks, garbage bags, and flexible packaging. Consequently sophisticated hardware, materials, and processing methods have been developed to yield film at very high output rates with both low dimensional variation and consistent solid-state properties.AcknowledgementsMaterials for Blown Film
