Heading: Rexam’s V1 and V2 Tubes

Text: After MWV began marketing the NoC® tube in late 2005, Rexam obtained a sample from one of its customers. Rexam analyzed the sample and obtained the commercially available EFEP from Daikin. In May 2006, Rexam launched its first invisible tube, the “V1” tube. In 2008, after learning of MWV’s patent applications, and in particular the claims’ crystallinity limitations, Rexam worked to develop a tube with an XRD crystallinity higher than 13%. It eventually settled on blending together different grades of EFEP to produce the “V2” tube, which Rexam contends has an XRD crystallinity of greater than 13%.
