Allied Development Corp. publishes “Barrier Materials for Rigid Packaging 2013 to 2017”, a global industry report which provides in-depth analyses of the barrier materials that are used for the production of rigid barrier packages. The study focuses on seven materials that provide desirable low-level oxygen transmission rates (OTR) between zero and 77.5cc/m²/day (5 cc/100 in²/day). The principal barrier materials reported on in the study include glass containers, PET resin, steel sheet, aluminum sheet, transparent oxide-coated containers, EVOH resin, and nylon resin
