In particular the NMMO technology has inspired new developments, recognizing that the cellulose/NMMO/water solution can be considered in many aspects as a melt. As an example, cellulose has been shaped by a blown-film process similar to conventional thermoplastics [33,34]. A schematic of the blow-extrusion process is shown in Figure 3.8. 

From hardware and materials through processing and properties, this book is intended to provide the reader with a comprehensive understanding of blown film extrusion through a useful balance of theory and practice. Included in this book are the answers to why effects behave the way that they do in the blown film process, so you can improve your ability to troubleshoot and improve systems. At the same time, current practices and equipment are emphasized to keep readers up-to-date with the most productive and efficient technology.

Blown-Film Processes. Bubble orientation technology permits simultaneous biaxial orientation directly from the melt (24) or by inflation of a quenched tube. With homogeneous films, the latter method may give films of slightly different properties than those of films produced on tenter frames. Melt orientation is less effective and properties are different because of lower orientation. 

Multilayer films are produced by both cast- and blown-film coextrusion. One of the key enabling technologies in the manufacture of these multilayer films has been preencapsulation of the VDC resin (205). Preencapsulation means that the VDC resin extrudate is completely encapsulated with a more thermally stable polymer, such as an ethylene-vinyl acetate copolymer, prior to entering the coextrusion die. Using this technique, the VDC resin is not directly exposed to the...
