Abstract

Cette invention concerne un film multicouche à orientation biaxiale et à thermorétractabilité uniaxiale, destiné à être utilisé en tant que film de surenveloppe pour des paquets de tabac ou des boîtes de cigarettes. Ce film est formé d'une couche centrale contenant du polypropylène constituant au moins 70 % en poids dudit film multicouche et d'au moins une couche protectrice contenant de la polyoléfine, située adjacente à ladite couche centrale. Pour préparer ce film, on oriente biaxialement un coextrudat puis on oriente ce dernier en l'étirant de 10 à 40 % dans le sens machine. La couche centrale contient du polypropylène isotactique et un modificateur qui réduit la cristallinité du centre contenant du polypropylène. Ces modificateurs peuvent être sélectionnés dans le groupe formé par polypropylène atactique, polypropylène syndiotactique, copolymère d'éthylène propylène syndiotactique, copolymère de propylène-butène-1 syndiotactique, therpolymère d'éthylène-propylène-butène syndiotactique et de polyéthylène à faible densité linéaire. La couche protectrice peut être sélectionnée dans le groupe formé par polypropylène, copolymère d'éthylène-propylène, polyéthylène et therpolymère d'éthylène-propylène-butène-1 et contient de l'huile de silicone.
