Abstract

Una pellicola di resina sintetica termoretraibile ad almeno tre strati, con uno strato centrale sostanzialmente in polietilene lineare a bassissima densità (V L D PE), cioè di peso specifico minore od al massimo uguale a 0,908, e con gli strati esterni formati da una miscela di un copolimero di propilene e di almeno un additivo.
