  1. 1. PACKAGINGBag-on-Valve – Optimal Solutionfor Pharma ProductsWith the total separation ofproduct and propellant, a bag withsuperior barrier properties, andcomplete oxygen protection, Bag-on-Valve is the optimal solutionfor pharmaceutical and healthproducts. Many products can bemade in a sterile presentation.Sterility is guaranteed – even whenthe can has been opened and usedfrequently over a long period oftime. With tax-based healthcare servicesburdened by increasingly higher costsfor pharmaceuticals and the ever-more stringent regulation governingthe introduction of a new drug onthe market, there is a growing trendmoving from prescription (Rx) to non-prescription, over-the-counter (OTC)products.
