Abstract

Procédé de production d'un film ou d'une feuille de matière thermoplastique orientée à couches multiples. Il consiste à faire passer le film ou la feuille initial dans une ou plusieurs paires de rouleaux presseurs dont la température est réglée à une valeur inférieure au point de ramollissement de celle des résines thermoplastiques des différentes couches présentant la température de ramollissement la plus basse, de manière que la feuille initiale soit laminée à un rapport supérieur à 1,5 et que sa transparence en soit améliorée. Domaine d'application : production de feuilles stratifiées en matière thermoplastique orientée.A process for producing a multi-layered oriented thermoplastic film or sheet. It consists in passing the initial film or sheet through one or more pairs of pressure rollers whose temperature is set to a value lower than the softening point than that of the thermoplastic resins of the different layers having the lowest softening temperature, from so that the initial sheet is laminated at a ratio greater than 1.5 and its transparency is improved. Field of application: production of laminated sheets of oriented thermoplastic material.
