多层聚烯烃薄膜及其制造方法与含有该薄膜之物件（一）;MULTILAYERED POLYOLEFIN FILMS, METHODS OF MANUFACTURE THEREOF AND ARTICLES COMPRISING THE SAME

摘要

本发明于此揭示出一种多层膜，其包含二层外层，其中每层外层皆包含聚乙烯；二层连结层(tie layer)，其中每层连结层皆包含一结晶嵌段复合物，其中每层连结层皆具有一第一面及一第二面，其等系彼此相对的，及其中每层连结层的第一面接触至少一层外层；及一核心层，其中该核心层包含聚丙烯，其中每层连结层的第二面接触该核心层，及其中该核心层具有厚度大于该多层膜的总厚度之50%。; where each outer layer comprises polyethylene; two tie layers; where each tie layer comprises a crystalline block composite; where each tie layer has a first face and a second face that are opposed to each other, and where the first face of each tie layer contacts at least one outer layer; and a core layer; where the core layer comprises a polypropylene; where the second face of each tie layer contacts the core layer; and where the core layer has a thicknesses that is greater than 50% of the total thickness of the multilayer film.
