Abstract
A polyethylene composition which when made into a film layer having a thickness of about 1 mil exhibits a machine direction (MD) 1% secant modulus of ≥190 MPa and an oxygen transmission rate (OTR) of ≥650 cm3 per 100 inch2 per day, and when made into a film layer having a thickness of about 2 mil exhibits a seal initiation temperature (SIT) of ≤100° C. and an area of hot tack window (AHTW) of ≥160 Newtons·° C.
