Title (EN) A PLANT AND METHOD FOR MAKING A PLASTIC FILM
(FR) INSTALLATION ET PROCÉDÉ DE FABRICATION D'UN FILM PLASTIQUE
Abstract:
(EN) A plant (10) for making a plastic film (11), in particular tubular or in a flat sheet, preferably intended for making sacks, bags and the like, comprising means (12) for forming the film (11) in the form of a bubble (15) starting with a respective molten mass of plastic material, which is fed to the forming means (12) by corresponding means (14) for extruding a relative raw material (13), which comprise a compounding extruder (18).
(FR) L'invention concerne une installation(10) de fabrication d'un film plastique (11), en particulier une feuille tubulaire ou plate, destinée de préférence à fabriquer des sacs, des poches et des articles similaires, comprenant un moyen (12) de formation du film (11) sous la forme d'une bulle (15) à partir d'une masse fondue respective de matière plastique, qui est introduite dans le moyen de formation (12) par un moyen correspondant (14) pour l'extrusion d'une matière première relative (13), qui comprend une mélangeuse-extrudeuse(18).
