摘要：
A composition comprising high density polyethylene (HDPE), calcium phthalate and a metal stearate is provided. Film that is prepared from this composition has excellent barrier properties—especially a low water vapor transmission rate (WVTR)—and is suitable for the preparation of packaging for dry foods such as crackers and cereals.
