PROPYLENE TERPOLYMER AND HEAT SEAL FILMS MADE THEREFROM
A propylene terpolymer is constructed that is particularly well suited for use in heat seal applications. The propylene terpolymer, for instance, can be used to form a heat seal layer on a multilayer film. The heat seal layer can be used to bond two opposing layers of film together for forming packages and other articles. The propylene terpolymer is formed with an increased random ethylene distribution that results in reduced polymer crystallinity, reduced melting temperature, and lower heat seal temperature.

HIGH CRYSTALLINE OLEFIN POLYMER FOR HIGH SPEED SPINNING
A polymer composition includes a low ethylene random copolymer that can be used to form a meltspun or spunbond article at high spinning velocities. The polymer composition has a low xylene soluble content, a high crystallinity, or both, while having reduced spin-break at high spinning velocities. The polymer composition also exhibits good fiber tenacity and fabric softness.
