Document Type and Number:

WIPO Patent Application WO2006102152

Kind Code:

A8

Abstract:

The present invention relates to film layers and compositions having improved hot tack properties. The compositions comprise at least one ethylene/a-olefin interpolymer, wherein the ethylene/a-olefin interpolymer may have, for example, a Mw/Mn from about 1.7 to about 3.5, at least one melting point, Tm, in degrees Celsius, and a density, d, in grams/cubic centimeter, wherein the numerical values of Tm and d correspond to the relationship: Tm > -2002.9 + 4538.5(d) - 2422.2(d)2.
