Biaxially oriented Nylon 66 film has been developed by a new tubular process. The relationship between the structure resulting from the manufacturing conditions and properties have been examined. A key technology of manufacturing is quenching of the melt, because of the high rate of polymer crystallization. The properties of biaxially oriented Nylon 66 film are found to be determined mainly by the degree of polymerization, the molecular and hydrogen bond plane structure, orientation within the film, and the degree of crystallinity. Toughness and high thermal resistance are also properties of this film. Therefore, applications for packaging have been examined, and a “retortable pouch” seems especially promising.
