    摘要: A cast multilayer film having a core layer made from ICP polypropylene having a thickness of at least 34% of the cast multilayer film, a first layer adjacent to the core layer and a second layer adjacent to the core layer each made from metallocene-based polyethylene (mPE) and having a thickness of from 1 to 33% of the cast multilayer film. The cast multilayer film has increased stiffness without substantial loss of optical, barrier and strength properties as compared with a film of total equal thickness made from the mPE of the first and second layers. The cast multilayer film has increased optical, barrier and strength properties without substantial loss of stiffness as compared with a film of total equal thickness made from the ICP of the core layer.
