Abstract

Διαδικασίες για την παραγωγή μιας όδευσης πλαστικού φιλμ στην οποία η αρχική όδευση του φιλμ από θερμοπλαστικό πολυμερισμένο υλικό στη βάση πολυαιθυλενίου, στο οποίο περιέχονται 1 μέχρι 70 μέρη βάρους πολυπροπυλενίου σε 100 μέρη βάρους πολυαιθυλενίου, διέρχεται μετά τη θέρμανση του μέσα από μια ψυχόμενη οπή κυλίνδρων. Στην αρχική διαδικασία το υλικό θερμαίνεται μέχρι το σημείο τήξης του βασικού υλικού (πολυαιθυλένιο) όχι όμως και το σημείο τήξης του πολυπροπυλενίου.
