Multilayer Film With Septum Layer
First Claim
1. A flexible multilayer film for forming a container defining a liquid-tight chamber for storing a liquid, said film comprising a first layer and a second layer, said first layer being a barrier layer and arranged inwardly of said second layer as seen in a direction from the chamber of the container formed from the said film, said second layer being a septum layer having self-sealing properties so as to seal around a hypodermic needle penetrating said film, and as seen in the above direction an innermost surface of said film being weldable.

Abstract
A flexible multilayer film for forming a container defining a liquid-tight chamber for storing a liquid is described here. The film comprises a first layer (1) and a second layer (2). The first layer (1) is a barrier layer, for example, 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, for example, a TPE layer, having self-sealing properties so as to seal around a hypodermic needle penetrating said film. As seen in 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.
