POLYETHYLENE-BASED RESIN FOR FORMING INFLATION FILM AND INFLATION FILM USING THE SAME AS BASE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a polyethylene resin giving an inflation film having excellent balance in physical properties such as shock resistance and little in one- sided wall thickness, and an inflation film having excellent balance in the physical properties produced by using the resin as a base material.;SOLUTION: The polyethylene resin for forming an inflation film has a soluble-material ratio in boiling hexane of ⊖1.5 mass % and a polydispersibility index of 30-60 at 190°C, and satisfies at least one out of the features that the rate of change of peak rations in the molecular weight distribution before and after granulation is ≥10%, and that the peak ratio in the molecular weight distribution before granulation is ≤0.8.;COPYRIGHT: (C)2002,JPO
