PROCEDE DE PRODUCTION D'UNE FEUILLE EN MATIERE THERMOPLASTIQUE ET FEUILLE OBTENUE PAR CE PROCEDE.

摘要

A method for producing a linear low density polyethylene (LLDPE) film by slot-die extrusion from an extrudate having an inherent draw resonance tendency whereby draw resonance is eliminated in the production of film at high speeds. Film of commercially uniform gauge thickness is obtained having significantly improved strength over films formed by conventional slot-die extrusion of LLDPE.
