The barrier pressure pack (BPP) system is a patented high-tech development from ХХХ. Up to now this system was only available as an unshaped cylindrical container. Due to modern can shaping technology the BPP system can now be presented in a design which ensures utmost shelf impact. The inner bag and the can are firmly connected to each other in the upper can area. The cavity between the pouch and the can bottom is used for holding the pressure medium. During use the inner bag is completely compressed with an emptying rate of up to 95 % of the filled substance. The glued-in aluminium pouch ensures the absolute separation of the filling good and propellant whilst providing the most effective diffusion barrier of all comparable systems. The aluminium pouch remains cylindrical in the shaped area. The shaped area of the can body provides a better grip for the consumer, even in a humid environment.
