Clariant specializes in protective packaging technologies, including multi-layer extrusion blow molded pharmaceutical containers. 

In order to inhibit the oxidation of sensitive drugs, our barrier bottles are engineered with six layers, one of which includes Ethylene Vinyl Alcohol (EVOH). Oxy-Guard® bottles effectively block oxygen ingress by a factor of 100 compared to regular bottles and also provide an excellent barrier against moisture. The six-layer structure can also incorporate a UV barrier, as well as customer-specific resins and design characteristics.

Clariant works with customers to customize performance parameters, materials and bottle design.

For a complete solution, Oxy-Guard bottles can be used in conjunction with PharmaKeep® oxygen absorbers which absorb the oxygen contained in the container headspace after drug filling and the small amount of oxygen that may still permeate into the container during shelf life.
