Patent

CA 2353953

The invention relates to a film composite for packaging purposes. Said film composite efficiently blocks the passage of water vapour and gas after sterilisation in a water bath or in water vapour at temperatures of more than 90 °C, and comprises a film consisting of polyethylene terephthalate (PET) with a coextruded layer consisting of polyethylene-2,6-naphthalate (PEN) on at least one side. The film has a 10 nm to 200 nm thick ceramic layer on at least one of the sides that are coated with PEN, said layer being produced by simultaneously vaporizing silicon dioxide (SiO2) and metallic silicon in a vacuum. The layer consists of SiO x, x being a number between 0.9 and 2. The composite film blocks the passage of water vapour and gases to a large extent after sterilisation in a water bath or in water vapour at temperatures of more than 90 ° C.

L'invention concerne un film composite destiné à des fins d'emballage. Ce film composite bloque efficacement le passage de la vapeur d'eau et de gaz après stérilisation dans un bain d'eau ou de la vapeur d'eau à des températures supérieures à 90 DEG C, et comprend un film de polyéthylène téréphthalate (PET) doté d'une couche de polyéthylène-2,6-naphthalate (PEN) coextrudée sur au moins une face. Le film a une couche céramique qui a une épaisseur de 10 nm à 200 nm et est produite par vaporisation simultanée de dioxyde de silicone (SiO2) et de silicone métallique sous vide, sur au moins une des faces revêtues de PEN. Cette couche consiste en SiOx, x valant un nombre de 0.9 à 2. Le film composite bloque largement le passage de la vapeur d'eau et de gaz après stérilisation dans un bain d'eau ou de la vapeur d'eau à des températures de plus de 90 DEG C.--
