POLYETHYLENE TYPE RESIN AND METHOD FOR PRODUCING THE SAME, AND INFLATION FILM USING THE SAME AS BASE MATERIAL
摘要
A polyethylene type resin, characterized in that it has a density of 940 to 970 kg/m<sp>3 </sp>and a long relaxation time component index of 1.5 to 10. The polyethylene type resin exhibits good extrusion characteristics and bubble stability during inflation forming, and also provides an inflation film which is excellent in impact resistance and the balance of physical properties in particular such as uniformity in thickness and further is reduced in the formation of fish eyes.
