发明名称 Multi-layered polyolefin laminated film.
摘要 <p>A three-layered laminated film consisting essentially of (A) a center layer consisting of a crystalline low molecular weight polyolefin having an intrinsic viscosity of 0.5 to 1.4 and (B) two surface layers disposed on both sides of the center layer and each consisting of a crystalline polyolefin (b) having a melting point higher than that of the crystalline low molecular weight polyolefin (a), whereby the thickness of the center layer (A) accounts for 30 to 98 %, especially 50 to 85 %, of the total thickness of the laminated film. The invention also relates to applications of the laminated film.</p><p>The laminated film of the invention has excellent finger-tearability and high toughness but little tendency to curl, to whiten when torn, to get turbid and fibrillated, and so forth. The laminated film is effectively used as an adhesive tape or other applications.</p>
