Nanotec and Mitsubishi Gas Chemical Corporation of Japan jointly developed PAXD6/nano-clay barrier M9, called Imperm, for the core of a three-layer PET bottle. Imperm is said to have a 100-fold lower oxygen transmission rate than PET, 50% and 70% higher than the standard PAMXD6 rejection rate for carbon dioxide and oxygen, respectively, and beer in a three-layer (PET/M9/PET) beer bottle. It can reach 180 days. US Honeywell is currently working on the development of a nylon nanocomposite Aegi OX with high barrier properties at the same cost as glass, which can reduce the oxygen transmission rate (OTR) of PA6 by 100 times and the oxygen infiltration rate. Almost zero. Using it as the core of a three-tiered beer bottle, the life of the loaded beer is 180 days. Polyvinyl alcohol (PVA) membranes have a very high barrier to gases and have a barrier to oxygen of about 1000 times that of conventional polyethylene membranes and 300 times that of polypropylene membranes. Barrier properties are comparable to EVOH but much cheaper. British Environmental Polymer Group announced that it has achieved a dry extrusion blown film. 75 Inch Conference Interactive Whiteboard As a 75 inch conference all-in-one machine, 75 inch Conference Interactive Whiteboard, microphones and conference software.
