Gerresheimer Showcases New Multilayer Plastic Container at CPhI

Gerresheimer will be presenting the first multilayer design in injection blow molding at CPhI. The company says that it is the first plastic container with a multilayer structure manufactured in an injection blow molding process. Test results of the new multilayer plastic container show that it offers sensitive pharmaceuticals extra protection against moisture vapor and oxygen permeability.

Pharmaceutical products risk degradation due to exposure to moisture vapour and oxygen. These drugs, therefore, require effective protection in the form of suitable packaging solutions, explains Niels Düring, Global Executive Vice President Plastic Packaging of Gerresheimer, in a press statement. “That’s why we have extended our established range of Duma-family products to include an additional product with improved barrier properties for enhanced and more reliable content protection."

US 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. Moreover, there is no need for changes on the filling line.
