1. A polyethylene having an alpha transition temperature of 120° C. or more, and
a crystalline region ratio on a temperature rising elution fractionation (TREF) graph of 12.5% or less, wherein the crystalline region ratio is obtained by dividing a graph area of a crystalline region having an elution temperature or more by a total graph area in percentage, wherein the elution temperature is a splitting point corresponding to a smallest peak between two highest peaks,
wherein the polyethylene is an ethylene homopolymer.
