摘要:
PROBLEM TO BE SOLVED: To provide a polypropylene based resin laminated film having a matte feeling and high fusion sealing strength. SOLUTION: The polyolefinic resin laminated film is composed of at least two polyolefinic resin layers containing at least a seal layer and a printing layer. The printing layer comprises a resin containing 95 wt.% or above of a propylene based block copolymer (C) and in the dispersion state of the elastomer component in the printing layer, the length ratio in the length/thickness direction in an MD direction is 2.5 or below and the circle equivalent diameter of the elastomer component of the printing layer is 0.5-2.0 μm.
