Document Type and Number:
Japanese Patent JP3142396
Kind Code:
B2
Abstract:
PURPOSE: To provide a composite polyolefin film for print laminate which is excellent in heat laminate aptitude for print laminate printing paper.
CONSTITUTION: In a composite film wherein a polyolefin thermofusible resin (layer B) is laminated on one side of a cast film (layer A) having polypropylene as a main component, a surface glossiness of the layer A is 110% or higher and its mean refractive index is within a range of 1.500-1.5080.
