摘要: Barrier films are prepared from a blend of two high density polyethylene blend components and a high performance organic nucleating agent. The two high density polyethylene blend components have substantially different melt indices. Large reductions in the moisture vapor transmission rate of the film are observed in the presence of the nucleating agent when the melt indices of the two blend components have a ratio of greater than 10/1. The resulting barrier films are suitable for the preparation of packaging for dry foods such as crackers and breakfast cereals.

摘要: The disclosure provides an ethylene copolymer having a density of from 0.912 g/cm3 to 0.925 g/cm3, a melt flow ratio (I21/I2) of from 20 to 30, and a normal comonomer distribution profile in a GPC-FTIR analysis, wherein the normal comonomer distribution profile has a slope of from −3.5 to −7.5, where the slope is defined as the number of short chain branches per 1000 carbons at a molecular weight of 300,000 minus the number of short chain branches per 1000 carbons at a molecular weight of 30,000. The ethylene copolymers have improved bulk density and when made into film, provide good physical properties.
