摘要： This invention pertains to a sealant film composition comprising at least two ethylene polymer component materials. One aspect of the invention relates to a multilayer structure having balanced sealant properties and comprising a sealant layer and a polypropylene layer, wherein the sealant layer comprises and is made from a polymer composition having particular molecular weight characteristics and a second ethylene polymer. A preferred embodiment of the present invention pertains to a medium density polyolefinic film and composition characterized by an excellent balance of a low seal initiation temperature and improved film modulus. The film and composition is comprised of and made from at least one lower density homogeneously branched ethylene polymer and at least one higher density heterogeneously or homogeneously branched ethylene polymer. The invention is particularly useful in those applications requiring fast seal times and good packaging dimensional stability such as, for example, cook-in packaging, hot-fill packaging, flowable material pouches, compression fill packaging, shrink film packaging and barrier shrink film packaging as well as biaxially oriented polypropylene (BOPP) film structures.

摘要： The present invention relates to nonwoven webs or fabrics. In particular, the present invention relates to nonwoven webs having superior abrasion resistance and excellent softness characteristics. The nonwoven materials comprise fibers made from of a polymer blend of isotactic polypropylene and reactor grade propylene based elastomers or plastomers together with from 100 to 2500 ppm (by weight of the fiber) of a slip agent. The isotactic polypropylene can be homopolymer polypropylene, and/or random copolymers of propylene and one or more alpha-olefins. The reactor grade propylene based elastomers or plastomers have a molecular weight distribution of less than about 3.5, and a heat of fusion less than about 90 joules/gm. In particular, the reactor grade propylene based elastomers or plastomers contains from 3 to 15 percent by weight of units derived from an ethylene and a melt flow rate of from 2 to 200 grams/ 10 minutes. Erucamide is the preferred slip additive.
