Blends of polypropylene and ethylene copolymer and films made from the blend. |
摘要 |
<p>A composition of matter comprises a blend of propylene homopolymer or copolymer, and ethylene copolymer. Ethylene vinyl acetate copolymer (EVA), very low density polyethylene (VLDPE), and ethylene alpha olefin copolymer are preferred ethylene copolymers. VLDPE with a high molecular weight (low melt index), and with a broad molecular weight distribution (high flow rate ratio) is preferred. A multilayer film comprises a first layer comprising a propylene homopolymer or copolymer, or blend, and at least one outer sealable layer.</p> |
