Multilayer polypropylene/polyethylene film with improved adhesion |
摘要 |
<p>The present invention relates to a multilayer structure comprising at least a first layer which predominantly comprises polypropylene and at least a second layer which is adjacent to the first layer and which predominantly comprises polyethylene having a density less than 0.935 g/cm 3 , the multilayer structure being characterized by having improved adhesion between the first and second layers. The improved adhesion is obtained by incorporating at least 5% by weight of a polyethylene resin having a density of 0.940 g/cm 3 or greater into the first layer, the second layer or both layers.</p> |
