In 2013 the development of child resistant cartons containing blister strips in a tray was started. Mid 2014 different sizes of Locked4Kids packaging was tested by Belgian testing institute BVI. With excellent results. A so called range certification was granted. It means that all sizes between the smallest and largest tested carton were automatically certified and there is no need to apply for certification every time a different size is demanded. Provided of course that the desired size stays within the certified range.
