Duma Twist-Off Protect
Extra Protection against Moisture Vapor and Oxygen Permeability
Gerresheimer AG presents with Duma Twist-Off Protect a new multilayer plastic container which offers sensitive pharmaceuticals extra protection against moisture vapor and oxygen permeability. It is the first plastic container with a multilayer structure manufactured in an injection blow molding process.
Gerresheimer has extended its established range of Duma-family products to include an additional product with improved barrier properties for enhanced and more reliable content protection. U.S. Pharmacopeia MVT (WVP) USP 38 <671> and Oxygen Transmission Rate OTR: ASTM F 1307 tests confirm that the container admits far lower levels of moisture vapor and oxygen than other standard solutions in the market.
Compared to extrusion blow molded containers it provides extremely good barrier properties due to a better control of geometry and thickness distribution. Duma Twist-Off Protect is fully compatilble with high-performance Duma Twist-Off closures (TE/CR/SF closures with and without desiccant) and the existing Duma Twist-Off range. At the same time there is no need for changes on the filling line.
