摘要：
The present invention relates to film layers and compositions having improved hot tack properties. The compositions comprise at least one ethylene/α-olefin interpolymer, wherein the ethylene/α-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.
