Patent

CA 2534562

The present invention relates to thermoplastic structures wherein the inner sealant layer of said structure comprises a polyethylene having a density from about 0.88 to about 0.96 and wherein the polyethylene is processed at a temperature ranging from about 150~F to about 500~F in order to prevent the release of extractable materials. The thermoplastic structures can be used independently to form a flexible packaging film or can be affixed to a second film structure or substrate to form a flexible packaging film. The flexible packaging films can be used for forming containers for the storing and transporting of organoleptic sensitive products.

L'invention concerne des structures thermoplastiques dans lesquelles la couche d'étanchéité intérieure comprend un polyéthylène d'une densité comprise entre environ 0,88 et environ 0,96 et dans lesquelles ce polyéthylène est traité à une température comprise entre environ 150 ·F et environ 500 ·F afin d'empêcher la libération de matériaux extractibles. Ces structures thermoplastiques peuvent être utilisées indépendamment pour former un film d'emballage flexible ou peuvent être fixées à une deuxième structure de film ou substrat de film pour former un film d'emballage flexible. Ces films d'emballage flexibles peuvent être utilisés pour former des contenants destinés au stockage et au transport de produits dont les propriétés organoleptiques peuvent être affectées.
