    摘要: A flexible multilayer film for forming a container defining a liquid-tight chamber for storing a liquid. The film comprises a first layer (1) and a second layer (2). The first layer (1) is a barrier layer, eg. a PCTFE layer, which is arranged inwardly of the second layer (2) as seen in a direction from the chamber of the container formed from the multilayer film. The second layer (2) is a septum layer, eg. a TPE layer, having self-sealing properties so as to seal around a hypodermic needle penetrating said film. As seen the above direction an innermost surface (5) of the film is weldable onto itself and is preferably made of a weldable layer (3) comprising PE and/or PP.
