发明名称 MULTILAYER FILM STRUCTURES HAVING IMPROVED SEAL AND TEAR PROPERTIES
摘要 A multilayer film structure having at least two layers wherein the first layer comprises poly(ethylene) having a density range from about 0.93 g/cc to 0.97 g/cc; and a second layer comprising poly(ethylene) having a density range from 0.89 g/cc to 0.93 g/cc wherein the second layer is capable of forming a heat seal. The multilayer film structure is capable of being laminated to another film structure or a packaging film component. The packages of the present invention are useful for the packaging of flowable materials.
