Abstract

Procédé de fabrication de feuilles plastiques en gaine renforcées par une couche de bandelettes enroulées en spirale autour de la feuille en gaine qui vient d'être extrudé, suffisamment consolidée par refroidissement Une couche adhésive extérieure en matière élastomère non réticulable est coextrudée en même temps que la feuille en gaine 1 en matériau thermoplastique, puis les bandelettes de renforcement 2 sont enroulées en spirale autour de l'ensemble. Cette feuille d'emballage à haute résistance, des sacs à haute résistance et des sacs conteneurs à grande capacité.Manufacturing process of sheathed plastic sheets reinforced with a layer of strips spirally wound around the sheathed sheet which has just been extruded, sufficiently consolidated by cooling An outer adhesive layer of non-crosslinkable elastomer material is coextruded at the same time as the sheath sheet 1 of thermoplastic material, then the reinforcing strips 2 are wound in a spiral around the assembly. This high strength packaging foil, high strength bags and large capacity container bags.
