Title (EN) MULTILAYER FILM WITH SEPTUM LAYER
(FR) FILM MULTICOUCHE DOTÉ D’UNE COUCHE MEMBRANE
Abstract:
(EN) 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.
(FR) La présente invention concerne un film multicouche souple permettant de former un récipient définissant une chambre étanche aux liquides destinée à stocker un liquide. Le film comprend une première couche (1) et une seconde couche (2). La première couche (1) est une couche barrière, une couche PCTFE par exemple, qui est disposée vers l’intérieur de la seconde couche (2) si on l’observe dans une direction partant de la chambre du récipient obtenue à partir du film multicouche. La seconde couche (2) est une couche membrane, une couche TPE par exemple, possédant des propriétés d’auto-étanchéité permettant d’assurer une étanchéité autour d’une aiguille hypodermique pénétrant ledit film. Ainsi observée dans la direction mentionnée ci-dessus, une surface plus interne (5) du film est soudable sur elle-même et est obtenue de préférence à partir d’une couche soudable (3) comprenant du PE et/ou du PP.
