Abstract
A polyethylene composition may include one or more types of ethylene-alpha-olefin copolymers. In the polyethylene composition, a successive self-nucleation and annealing (SSA) thermogram representing a relationship between heat flow and temperature satisfies Equation 1:0.16≤B/A≤0.4. In Equation 1, A means an area for an entire temperature region in the SSA thermogram, and B means an area for a temperature region of 128° C. or higher in the SSA thermogram. A biaxially stretched film may include the polyethylene composition.
