The epitaxial crystallization of LDPE on highly oriented iPP films was studied by means of electron microscopy. The electron microsraphs of LDPE/iPP layered films indicate that after heat treatment and recrystallization, a thin layer of LDPE can form a cross-hatched lamellar structure on the oriented iPP films. The LDPE lameliae incline ±40°to the drawing direction of iPP film. Electron diffraction patterns confirmed that the caxes of LDPE are ±50° apart from the c axes of iPP.The contact planes are (010) of iPP and (100) of LDPE.
