Abstract

Film coestruso termoretraibile a tre strati dei quali lo strato intermedio è costituito da polietilene lineare a bassa densità o da polietilene lineare a media densità eventualmente addizionati con resine idrocarboniche idrogenate o altre resine, mentre i due strati esterni sono costituiti da polipropilene oppure da copolimero etilene-propilene addizionati con resine dello stesso gruppo impiegato nello strato intermedio.
